<hr />
<div>So what do you need and where do you get the parts?<br />
<br />
Part quantities and suggested suppliers are in the [[Mendel assembly data sheet]].<br />
<br />
From the BOM you'll see that you need to get hold of about 10 different types of materials. '''Before you buy anything''', here is some important information you should know, including a [[#Costing|cost breakdown]] at the end:<br />
<br />
== Bar ==<br />
<br />
All bar is ø 8 mm diameter.<br />
Generally you can survive just fine on “Bright Zinc Plated" (BZP).<br />
BZP is better than Bright Mild Steel (BMS) as BMS will rust unless coated with oil.<br />
A2 steel will feel nicer and be straighter, but is more expensive. <br />
It is best to buy in 1m lengths and then cut to size.<br />
See the [[Mendel assembly data sheet]] for the number of 1m lengths needed.<br />
<br />
== Bearings ==<br />
<br />
Mendel does not impart big loads on any of the bearings, therefore high specification bearings are not at all needed. Get the cheapest ones you can.<br />
<br />
== Belt ==<br />
<br />
Make sure you get a Contitech Synchroflex tooth profile, or an equivalent, which allows enough room for chunky teeth. For example, HTD (round profile) does not allow enough room for teeth on a tight diameter.<br />
<br />
RepRap attempts to print its own parts wherever possible. This includes toothed drive pulleys. 5 mm pitch (or imperial equivalent XL pitch, 0.2") belts have been investigated because at the time of research a 5 mm pitch was the most achievable to print. See the [[Mendel assembly data sheet]] for the belt specifications.<br />
<br />
Belt need to be split to a width of 5mm. This can be achieved using the [[Belt splitter jig]] (two reprapped parts).<br />
<br />
== Extruder parts ==<br />
<br />
The extruder design is frequently updated: check the [[Mendel extruder|Mendel extruder page]] for the latest procurement/preparation documentation.<br />
<br />
== Fasteners ==<br />
<br />
Cheap BZP parts are fine. <br />
<br />
Mendel uses two different types of nut: nylock and standard. As an alternative to nylocks, however, you may prefer to use standard nuts and use a thread locker compound, for example brand name LocTite 243, and apply a small amount where ever a nyloc is called for. A [http://en.wikipedia.org/wiki/Thread-locking_fluid thread locker] is a compound that sets in the absence of air.<br />
<br />
== Motors ==<br />
<br />
Mendel has been designed to cater for either NEMA 17 or NEMA 14 specification stepper motors. Buy whichever is easier and cheaper for you. If going for the smaller NEMA 14 motors, aim for the high torque option. You need approximately 1400 g.cm of holding torque or more to be safe.<br />
<br />
== PCB/Electronics ==<br />
<br />
You’ll need a fully assembled electronics kit (the assembly directions here support [http://dev.www.reprap.org/bin/view/Main/Generation3Electronics Generation 3 electronics]). You can buy these ready assembled, or as a kit that you can [http://dev.www.reprap.org/bin/view/Main/HotplateReflowTechnique solder up yourself].<br />
<br />
== Thin sheet ==<br />
<br />
This is needed for the optoswitch flags. <br />
Thickness must be less than 2 mm.<br />
You will need a minimum total area of 8 cm x 5 cm.<br />
Material must be opaque to infra-red light (the optoswitch uses IR light).<br />
Material must be pliable (easy to bend into shape).<br />
Aluminium sheet is good. Some New Zealanders have been known to use beer cans, which are easy to cut with ordinary scissors...<br />
<br />
== Reprapped parts ==<br />
<br />
[[Image:total-build-in-440x440-envelope.PNG|thumb|Mendel's reprapped parts]]<br />
<br />
You need to get hold of a set of reprapped parts. Many people will be upgrading to Mendel from RepRap Version I "Darwin". Darwin can print all Mendel's parts. So can all the commercial RepRap-derived machines available from the suppliers on the [http://reprap.org/bin/view/Main/PartsSupplies Get-a-RepRap-Kit page]. There is a [http://dev.forums.reprap.org/list.php?94 page on the RepRap forums] where people offer reprapped parts for sale, and [http://dev.forums.reprap.org/list.php?95 another forum page where people post wanted notices]. Finally, if you know someone with a RepRap who could print the parts for you, offer them some beer...<br />

<br />
A small list of commercial Rapid Prototyping Services is [http://reprap.org/bin/view/Main/PartsSupplies here], but be warned, RP bureaus generally charge extortionate rates.<br />
<br />
== Thick Sheet ==<br />
<br />
Sheet must range between 4 mm - 6 mm thickness.<br />
You will need a minimum total area of 42 cm x 40 cm.<br />
'''Your sheet must be flat as this is what you’ll be printing on!''' <br />
MDF (Medium Density Fibre Board) is definitely best as it laser cuts or saws easily and is usually very flat. It is also cheap.<br />
Plywood is a good option if you require extra strength in your machine, but is harder to work with, either with a saw or a laser cutter.<br />
If using polymer make sure it is flat. Cast polymer is the flattest, but may not laser cut as well as extruded polymer. However, extruded polymer is typically not flat.<br />
When storing sheets always store them face down on a flat surface. Stacking them at an angle on their side will ruin their flatness.<br />
<br />
== Studding ==<br />
<br />
All studding (''i.e.'' threaded rod) is M8. <br />
BZP is fine.<br />
It is best to buy in 1m lengths and then cut to size. <br />
See the [[Mendel assembly data sheet]] for required lengths.<br />

These pages will show you how to build the mechanical structure of RepRap Version II "Mendel". Check out the [[Mendel Overview|overview]] to get a fast introduction to Mendel's design. The [[Mendel assembly data sheet]] has been designed to provide all the procurement and assembly data you need, and can be relied upon if you prefer not to follow instructions. However, it's recommended that you do assembly in the order of the list below.<br />

<br />
The machine on the right is the RepRap printer, which we call "Mendel" after the [http://en.wikipedia.org/wiki/Gregor_Mendel father of genetics]. It's the second, new-improved version: small enough to fit on your desk, but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers or online, and parts which it can make for itself - all the translucent structural components you can see.<br />
<br />
In the picture, behind the machine, you can see the RepRap software which you can use to print [http://www.thingiverse.com your thing]. We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.<br />
<br />
You will find directions to all the files in the relevant instructions.<br />

== Mendel vs. Darwin ==<br />
<br />
Mendel is the latest generation RepRap machine. Mendel supersedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity for tool changing (to follow very shortly)<br />
* Lighter and more portable<br />
<br />
This video illustrates these improvements:<br />
<br />
<videoflash type="vimeo">6983001|640|480</videoflash><br />
<br />
For a numerical comparison [http://blog.reprap.org/2009/09/darwin-vs-wedge-numbers.html see this blog post].</div>Skinnyedhttps://reprap.org/mediawiki/index.php?title=Mendel_assembly_data_sheet&diff=3097Mendel assembly data sheet2009-10-20T22:33:21Z<p>Skinnyed: </p>

<br />
If you are prepared to share any improvements you find along the way please register with the wiki now: there is a spam-prevention cooling period after registration. We ''greatly'' appreciate any improvement on assembly data - particularly towards better, cheaper, local suppliers. Your contributions will improve the experience for all the builders that follow you.<br />
<br />
''Please do not create additional spreadsheets, simply update to the existing data sheet. This keeps the data central.''<br />
<br />
When updating the spreadsheet, please remember that this is a public document and ensure that your additions are:<br />
<br />
* Efficient to navigate<br />
* Thorough and correct (use the 'insert note' feature over cells where appropriate)<br />
* Hyperlinked where possible<br />
* For supplier's parts please display the link as the part number, this way if the link dies the part can still be traced manually with the part number on the supplier's site.<br />

Roll the frame onto its back, and position the x-axis into the top end.<br />
Thread the z-bars through the leadscrew base, x-axis and top-clamp.<br />
Fasten z-bars.<br />
<br />
[[Image:installing-x-axis-assembly.PNG|500px]] <br />
<br />
With the frame still on its back, slide the partly assembled z-leadscrew through the leadscrew base and screw into the M8 trapped nut on the x-axis.<br />
Screw in until bearing sits flush in leadscrew base.<br />
Fasten with caps.<br />
<br />
[[Image:installing-z-leadscrew.PNG|500px]]<br />
<br />
Complete the leadscrew assembly with the parts which were temporarily removed in the initial assembly. <br />
Repeat for other side.<br />
<br />
[[Image:z-leadscrew-assembly.PNG|500px]] <br />
<br />
Keep frame on its back.<br />
Whilst still keeping the x-axis at the top end of the leadscrews, rotate the leadscrews until the x-axis is approximately square.<br />
Better calibration will be achieved later, however, both leadscrews should turn fairly freely.<br />
Attach the z-belt.<br />

Wind x-axis down to the bed, as this will get in the way.<br />
Wind by lifting the frame up to pull the z-belt.<br />
Do not let nozzle closer than 1 cm to bed – if the bed slides around before calibration it may damage the nozzle by scraping against it.<br />
Position circuit board at the top of the front side, as high as possible (1).<br />
Use four bolts per clamp and fasten securely as this element improves chassis rigidity (2).<br />

<br />
[[Image:Carriage-upper-assembly.PNG|500px|border]]<br />
<br />
Assemble the two halves together (3) using 6 M4x40 caps (don't forget the optoflag!). Tighten the middle two caps, keep the outer two pairs loose. When fully assembled use a piece of ø8 mm bar to set the distances between the bearings. Slide the bar between the bearings and tighten/slacken the outer two pairs of M4x40 caps to achieve a smooth, low resistance, running fit.<br />

Assembly is also compatible for NEMA 14 motors.<br />
<br />
'''For all axis motors''' you'll need to file your own flats onto the drive shafts. There's a few essential tips for doing this:<br />
<br />
* Put blue-tak/tape around the base of the drive shaft to prevent alloy filings getting dragged into the bearings (the motor's magnets will try to suck them in!)<br />
* The flat should extend down the shaft to ~ 3mm from the face of the motor. <br />
* The depth of the flat depends on your drive pulley hole profile, so have a good look before you do this. <br />
* Ensure flat depths are even or you'll get a wobbly drive pulley.<br />
* The fit should be tight so that it won't come off on its own, but not too tight or you'll split the drive pulley. <br />
* When pushing the drive pulley onto the motor shaft make sure the rear of the shaft is supported so that you can lightly tap the pulley with a hammer. Failure to support the back of the motor shaft will result in a broken motor. <br />
* While you're tooled up you may as well do all the motors in one shot.<br />
<br />

Fit bars. Make sure the bars do not touch the bearings.<br />

<hr />
<div>== Time and place ==<br />
<br />
After preparing materials, the assembly should take a weekend.<br />
You will need at least 2 square meters of assembly space, some good tunes and copious amount of tea.<br />
<br />
== Assembly data sheet ==<br />
<br />
The [[Mendel assembly data sheet]] enables the experienced ‘bot assemblers to survive with the spreadsheet alone. However, if this is your first time, the following pages will lead you through the assembly from start to finish, referring to the spreadsheet where appropriate. <br />
<br />
== Jig and Measurement distances ==<br />
<br />
[[Image:Jigging.jpg|300px|right|border|Using a spacer bar to calibrate the y-axis]] <br />
<br />
Your machine will need careful calibration during assembly. Two different techniques are required: jigging and measuring. Jigged distances will be labelled on diagrams with a “'''J'''”, and measured distances will be labelled on diagrams with an “'''M'''”. You will need refer to the [[Mendel assembly data sheet]] for the value of these distances.<br />
<br />
=== Jigging ===<br />
<br />
Use spacer bars to calibrate common distances. A good arrangement for the y-axis jig is to tape a longer bar over the top of the spacer bar (see pic) to achieve a perpendicular alignment. The top bar only has to be longer by ~10 mm at each end. This arrangement is not necessary for the other two frame jigs.<br />
<br />
=== Measuring ===<br />
<br />
Best use a zero ended rule if you have one, but an everyday ruler or tape measure will suffice.<br />
<br />
== Important assembly notes ==<br />
<br />
<br />
<br />
* Always use plain nuts in captive nut traps in RP parts. Never use nylocks as the rotation force might strip the flats in the trap.<br />
* Apart from the above case, use nylocks wherever possible as this reduces the likelihood of fasteners loosening due to vibration.<br />
* Don’t skimp on washers for the same reason as above.<br />
* Fully tighten all nuts as you assemble unless instructed to do otherwise.<br />
* Always enclose a bearing with a standard washer each side to ensure smooth running (see pic).<br />

<hr />
<div>Once you’ve got your raw stock, you need to prepare some of it:<br />
<br />
== Bar ==<br />
<br />
Check the [[Mendel assembly data sheet]] for specifications.<br />
Cut the bar to size using a hack saw and tape measure.<br />
Use soft vice pads so as not to damage the bar surface or threads.<br />
If using mild steel, oil immediately to avoid rusting.<br />
File off all burrs.<br />
<br />
== Belt ==<br />
<br />
Check the [[Mendel assembly data sheet]] for specifications.<br />
Use the [[Belt splitter jig]] to cut the widths you need.<br />
'''Do not break the z-belt loop – this needs to be continuous!'''<br />
<br />
== Extruder parts ==<br />
<br />
The extruder design is frequently updated: check the [[Mendel extruder|Mendel extruder page]] for the latest procurement/preparation documentation.<br />
<br />
== Thin sheet ==<br />
<br />
[[Image:Opto-flag-templates.jpg|thumb|Optoswitch templates from thin sheet]]<br />
<br />
To prepare your optoswitch flags you need to drill and cut the sheet to shape using tin snips/scissors, depending on sheet thickness. <br />
Either use the dimensions shown [[media:Opto-flag-templates.png|here]] or print a template from the [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/cartesian-robot-m4/imported-custom-parts/thin-sheet-templates dxf file]. (Make sure your printer doesn’t scale the template! Measure the reference dimension after printing to check).<br />
<br />
== Reprapped parts ==<br />
<br />
Clean out all holes and remove support material if necessary.<br />
<br />
== Thick sheet ==<br />
<br />
Thick sheet components are best cut on a laser cutter.<br />
<br />
This [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/cartesian-robot-m4/imported-custom-parts/thick-sheet-templates zip file] contains dxf’s for all individual sheet components, including a dxf of them all grouped together for a one-shot cut.<br />
<br />
If doing manually, or using a hacksaw or - better - a fretsaw, apologies. Whilst it is still possible, the author admits it will not be easy. One of the drawbacks of making the design compact was increasing complexity, and the y-chassis has many complex cutting features in it. Add +0.4 mm on to all nominal hole diameters to ensure a clearance fit for bolts. For example a hole for an M4 bolt should be drilled to 4.4 mm (though 4.5mm will also suffice).<br />
<br />
== Studding ==<br />
<br />
Same as bar.<br />

<hr />
<div>So what do you need and where do you get the parts?<br />
<br />
Part quantities and suggested suppliers are in the [[Mendel assembly data sheet]].<br />
<br />
From the BOM you'll see that you need to get hold of about 10 different types of materials. '''Before you buy anything''', here is some important information you should know, including a [[#Costing|cost breakdown]] at the end:<br />
<br />
== Bar ==<br />
<br />
All bar is ø 8 mm diameter.<br />
Generally you can survive just fine on “Bright Zinc Plated" (BZP).<br />
BZP is better than Bright Mild Steel (BMS) as BMS will rust unless coated with oil.<br />
A2 steel will feel nicer and be straighter, but is more expensive. <br />
It is best to buy in 1m lengths and then cut to size.<br />
See the [[Mendel assembly data sheet]] for the number of 1m lengths needed.<br />
<br />
== Bearings ==<br />
<br />
Mendel does not impart big loads on any of the bearings, therefore high specification bearings are not at all needed. Get the cheapest ones you can.<br />
<br />
== Belt ==<br />
<br />
Make sure you get a Contitech Synchroflex tooth profile, or an equivalent, which allows enough room for chunky teeth. For example, HTD (round profile) does not allow enough room for teeth on a tight diameter.<br />
<br />
RepRap attempts to print its own parts wherever possible. This includes toothed drive pulleys. 5 mm pitch (or imperial equivalent XL pitch, 0.2") belts have been investigated because at the time of research a 5 mm pitch was the most achievable to print. See the [[Mendel assembly data sheet]] for the belt specifications.<br />
<br />
Belt need to be split to a width of 5mm. This can be achieved using the [[Belt splitter jig]] (two reprapped parts).<br />
<br />
== Extruder parts ==<br />
<br />
The extruder design is frequently updated: check the [[Mendel extruder|Mendel extruder page]] for the latest procurement/preparation documentation.<br />
<br />
== Fasteners ==<br />
<br />
Cheap BZP parts are fine.<br />
<br />
== Motors ==<br />
<br />
Mendel has been designed to cater for either NEMA 17 or NEMA 14 specification stepper motors. Buy whichever is easier and cheaper for you. If going for the smaller NEMA 14 motors, aim for the high torque option. You need approximately 1400 g.cm of holding torque or more to be safe.<br />
<br />
== PCB/Electronics ==<br />
<br />
You’ll need a fully assembled electronics kit (the assembly directions here support [http://dev.www.reprap.org/bin/view/Main/Generation3Electronics Generation 3 electronics]). You can buy these ready assembled, or as a kit that you can [http://dev.www.reprap.org/bin/view/Main/HotplateReflowTechnique solder up yourself].<br />
<br />
== Thin sheet ==<br />
<br />
This is needed for the optoswitch flags. <br />
Thickness must be less than 2 mm.<br />
You will need a minimum total area of 8 cm x 5 cm.<br />
Material must be opaque to infra-red light (the optoswitch uses IR light).<br />
Material must be pliable (easy to bend into shape).<br />
Aluminium sheet is good. Some New Zealanders have been known to use beer cans, which are easy to cut with ordinary scissors...<br />
<br />
== Reprapped parts ==<br />
<br />
[[Image:total-build-in-440x440-envelope.PNG|thumb|Mendel's reprapped parts]]<br />
<br />
You need to get hold of a set of reprapped parts. Many people will be upgrading to Mendel from RepRap Version I "Darwin". Darwin can print all Mendel's parts. So can all the commercial RepRap-derived machines available from the suppliers on the [http://reprap.org/bin/view/Main/PartsSupplies Get-a-RepRap-Kit page]. There is a [http://dev.forums.reprap.org/list.php?94 page on the RepRap forums] where people offer reprapped parts for sale, and [http://dev.forums.reprap.org/list.php?95 another forum page where people post wanted notices]. Finally, if you know someone with a RepRap who could print the parts for you, offer them some beer...<br />
<br />
* Part files for the cartesian robot are available [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/cartesian-robot-m4/printed-parts here].<br />
* Part files for the Mendel extruder are available [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/extruders/pinch-wheel/wedge-604 here].<br />
<br />
Check the thumbnail for a visual glossary of all the RP parts.<br />
<br />
[[Image:printed-parts-glossary.PNG|thumb|Reprapped parts glossary]]<br />
<br />
A small list of commercial Rapid Prototyping Services is [http://reprap.org/bin/view/Main/PartsSupplies here], but be warned, RP bureaus generally charge extortionate rates.<br />
<br />
== Thick Sheet ==<br />
<br />
Sheet must range between 4 mm - 6 mm thickness.<br />
You will need a minimum total area of 42 cm x 40 cm.<br />
'''Your sheet must be flat as this is what you’ll be printing on!''' <br />
MDF (Medium Density Fibre Board) is definitely best as it laser cuts or saws easily and is usually very flat. It is also cheap.<br />
Plywood is a good option if you require extra strength in your machine, but is harder to work with, either with a saw or a laser cutter.<br />
If using polymer make sure it is flat. Cast polymer is the flattest, but may not laser cut as well as extruded polymer. However, extruded polymer is typically not flat.<br />
When storing sheets always store them face down on a flat surface. Stacking them at an angle on their side will ruin their flatness.<br />
<br />
== Studding ==<br />
<br />
All studding (''i.e.'' threaded rod) is M8. <br />
BZP is fine.<br />
It is best to buy in 1m lengths and then cut to size. <br />
See the [[Mendel assembly data sheet]] for required lengths.<br />

Make sure you get a Contitech Synchroflex tooth profile, or an equivalent, which allows enough room for chunky teeth. For example, HTD (round profile) does not allow enough room for teeth on a tight diameter.<br />
<br />
RepRap attempts to print its own parts wherever possible. This includes toothed drive pulleys. 5 mm pitch (or imperial equivalent XL pitch, 0.2") belts have been investigated because at the time of research a 5 mm pitch was the most achievable to print. See the [[Mendel assembly data sheet]] for the belt specifications.<br />
<br />
Belt need to be split to a width of 5mm. This can be achieved using the [[Belt splitter jig]] (two reprapped parts).<br />
<br />
== Extruder parts ==<br />
<br />
The extruder design is frequently updated: check the [[Mendel extruder|Mendel extruder page]] for the latest procurement/preparation documentation.<br />
<br />
== Fasteners ==<br />
<br />
Cheap BZP parts are fine.<br />
<br />
== Motors ==<br />
<br />
Mendel has been designed to cater for either NEMA 17 or NEMA 14 specification stepper motors. Buy whichever is easier and cheaper for you. If going for the smaller NEMA 14 motors, aim for the high torque option. You need approximately 1400 g.cm of holding torque or more to be safe.<br />
<br />
== PCB/Electronics ==<br />
<br />
You’ll need a fully assembled electronics kit (the assembly directions here support [http://dev.www.reprap.org/bin/view/Main/Generation3Electronics Generation 3 electronics]). You can buy these ready assembled, or as a kit that you can [http://dev.www.reprap.org/bin/view/Main/HotplateReflowTechnique solder up yourself].<br />
<br />
== Thin sheet ==<br />
<br />
This is needed for the optoswitch flags. <br />
Thickness must be less than 2 mm.<br />
You will need a minimum total area of 8 cm x 5 cm.<br />
Material must be opaque to infra-red light (the optoswitch uses IR light).<br />
Material must be pliable (easy to bend into shape).<br />
Aluminium sheet is good. Some New Zealanders have been known to use beer cans, which are easy to cut with ordinary scissors...<br />
<br />
== Reprapped parts ==<br />
<br />
[[Image:total-build-in-440x440-envelope.PNG|thumb|Mendel's reprapped parts]]<br />
<br />
You need to get hold of a set of reprapped parts. Many people will be upgrading to Mendel from RepRap Version I "Darwin". Darwin can print all Mendel's parts. So can all the commercial RepRap-derived machines available from the suppliers on the [http://reprap.org/bin/view/Main/PartsSupplies Get-a-RepRap-Kit page]. There is a [http://dev.forums.reprap.org/list.php?94 page on the RepRap forums] where people offer reprapped parts for sale, and [http://dev.forums.reprap.org/list.php?95 another forum page where people post wanted notices]. Finally, if you know someone with a RepRap who could print the parts for you, offer them some beer...<br />
<br />
* Part files for the cartesian robot are available [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/cartesian-robot-m4/printed-parts here].<br />
* Part files for the Mendel extruder are available [https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/solid-models/extruders/pinch-wheel/wedge-604 here].<br />
<br />
Check the thumbnail for a visual glossary of all the RP parts.<br />
<br />
[[Image:printed-parts-glossary.PNG|thumb|Reprapped parts glossary]]<br />
<br />
A small list of commercial Rapid Prototyping Services is [http://reprap.org/bin/view/Main/PartsSupplies here], but be warned, RP bureaus generally charge extortionate rates.<br />
<br />
== Thick Sheet ==<br />
<br />
Sheet must range between 4 mm - 6 mm thickness.<br />
You will need a minimum total area of 42 cm x 40 cm.<br />
'''Your sheet must be flat as this is what you’ll be printing on!''' <br />
MDF (Medium Density Fibre Board) is definitely best as it laser cuts or saws easily and is usually very flat. It is also cheap.<br />
Plywood is a good option if you require extra strength in your machine, but is harder to work with, either with a saw or a laser cutter.<br />
If using polymer make sure it is flat. Cast polymer is the flattest, but may not laser cut as well as extruded polymer. However, extruded polymer is typically not flat.<br />
When storing sheets always store them face down on a flat surface. Stacking them at an angle on their side will ruin their flatness.<br />
<br />
== Studding ==<br />
<br />
All studding (''i.e.'' threaded rod) is M8. <br />
BZP is fine.<br />
It is best to buy in 1m lengths and then cut to size. <br />
See the [[Mendel assembly data sheet]] for required lengths.<br />
<br />
<br />
== Costing ==<br />
<br />

The machine on the right is the RepRap printer, which we call "Mendel" after the father of genetics. It's the second, new-improved version: small enough to fit on your desk, but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers or online, and parts which it can make for itself - all the translucent structural components you can see.<br />

We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395.

== Mendel vs. Darwin ==<br />
<br />
Mendel is the latest generation RepRap machine. Mendel supersedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity of tool changing (to follow very shortly)<br />
* Lighter and more portable<br />

Mendel is the latest generation RepRap machine. Mendel supersedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity of tool changing (to follow very shortly)<br />
* Lighter and more portable<br />

The machine on the right is the RepRap printer, which we lovingly call "Mendel". It's the second, new-improved version: small enough to fit on your desk but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers, and parts which it can make for itself - all the translucent structural components.<br />
<br />
In the picture, behind the machine, you can see the RepRap software which you can use to print [http://www.thingieverse.com your thing]. We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.<br />

== Mendel vs. Darwin ==<br />
<br />
Mendel is the latest generation RepRap machine. Mendel supercedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity of tool changing<br />
<br />

The machine on the right is the RepRap printer, which we lovingly call "Mendel". It's the second, new-improved version: small enough to fit on your desk but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers, and parts which it can make for itself - all the translucent structural components.<br />
<br />
In the picture, behind the machine, you can see the RepRap software which you can use to print [http://www.thingieverse.com your thing]. We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.<br />

Assemble the lower carriage first (1). Note trapped nuts.<br />
<br />
[[Image:Carriage-lower-assembly.PNG|500px|border]]<br />
<br />
Then assemble the upper carriage (2).<br />
<br />
[[Image:Carriage-upper-assembly.PNG|500px|border]]<br />
<br />
Assemble the two halves together (3) using 6 M4x40 caps (don't forget the optoflag!). Tighten the middle two caps, keep the outer two pairs loose. When fully assembled use a piece of ø8 mm bar to set the distances between the bearings. Slide the bar between the bearings and tighten/slacken the outer two pairs of M4x40 caps to achieve a smooth, low resistance, running fit.<br />
<br />
[[Image:Carriage-without-extruder-assembly.PNG|500px|border]]<br />
<br />
Finally assemble the extruder (4).<br />

<br />
Assembly is also compatible for NEMA 14 motors.<br />
<br />
'''For all axis motors''' you'll need to file your own flats onto the drive shafts. There's a few essential tips for doing this:<br />
<br />
* Put blue-tak/tape around the base of the drive shaft to prevent alloy filings getting dragged into the bearings (the motor's magnets will try to suck them in!)<br />
* The flat should extend down the shaft to ~ 3mm from the face of the motor. <br />
* The depth of the flat depends on your drive pulley hole profile, so have a good look before you do this. <br />
* Ensure flat depths are even or you'll get a wobbly drive pulley.<br />
* The fit should be tight so that it won't come off on its own, but not too tight or you'll split the drive pulley. <br />
* When pushing the drive pulley onto the motor shaft make sure the rear of the shaft is supported so that you can lightly tap the pulley with a hammer. Failure to support the back of the motor shaft will result in a broken motor. <br />
* While you're tooled up you may as well do all the motors in one shot.<br />
<br />
[[Image:x-motor-bracket-assembly.PNG|500px]] <br />
<br />
Fit bars. Make sure the bars do not touch the bearings.<br />

For all axis motors you'll need to file your own flats onto the drive shafts. When doing this, put blue-tak/tape around the base of the shaft to prevent alloy filings from the shaft getting dragged into the bearings (the motor's magnets will try to suck them in!). The flat should extend down the shaft to ~ 3mm from the face of the motor. The depth of the flat depends on your drive pulley hole profile, so have a good look before you do this. hHe fit should be tight, but not so tight that the drive pulley splits when you push it on.<br />

When pushing the drive pulley onto the motor shaft make sure the rear of the shaft is supported so that you can lightly tap the pulley with a hammer. Failure to support the back of the motor shaft will result in a broken motor. <br />

<div>This page describes how to wire up RepRap Version II "Mendel".<br />
<br />
[[Image:wiring-diagram.png|900px]]<br />
<br />
This is the overall Mendel wiring diagram; click the image for a full-resolution version. The wiring diagram is stored as an [[http://cadsoft.de/ Eagle]] schematic in the [[http://reprap.svn.sourceforge.net/viewvc/reprap/trunk/mendel/electronics/mendel-wiring-diagram.sch?view=log RepRap subversion repository here]]. Check that link for the latest revisions and corrections. In the diagram above multi-way connections are shown as thick lines with a number next to them. The number is the number of wires in the connection. Single wires are thin and unnumbered.<br />
<br />
One Mendel will need:<br />
<br />
* A [http://dev.www.reprap.org/bin/view/Main/Motherboard_1_2 RepRap Motherboard],<br />
* A [[Mendel USB and power connector]],<br />
* 3 [http://dev.www.reprap.org/bin/view/Main/Stepper_Motor_Driver_2_3 RepRap Stepper drivers],<br />
* 3 [http://dev.www.reprap.org/bin/view/Main/OptoEndstop_2_1 RepRap Opto Endstops], and<br />
* As many [http://dev.www.reprap.org/bin/view/Main/Extruder_Controller_2_2 RepRap extruder controllers] as you have extruders.<br />
<br />
Follow those links for details on the individual printed circuit boards.<br />
<br />
The power wiring is not shown on the diagram for clarity, but it is very simple. The 12 volts from the [[Mendel USB and power connector]] is connected in parallel to the three stepper driver boards and to all the extruder controller boards. The Motherboard does not need to be connected to Mendel's internal power connectors. It is powered by the USB connection from the computer.<br />
<br />
The extruders are connected in parallel to the RS485 and to the SDA and SCL ports on the Motherboard. The system only has four connectors for these on the Motherboard, but you can chain these together up to any reasonable number (in theory it should be possible to drive 64 extruders at once...).<br />

The machine on the right is the RepRap printer, which we lovingly call "Mendel". It's the second, new-improved version: small enough to fit on your desk but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers, and parts which it can make for itself - all the translucent structural components.<br />
<br />
In the picture, behind the machine, you can see the RepRap software which you can use to print [http://www.thingieverse.com your thing]. We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.<br />

== Mendel vs. Darwin ==<br />
<br />
Mendel is the latest generation RepRap machine. Mendel supercedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity of tool changing<br />
<br />

<div>Mendel uses a thermoplast extruder based on RepRap's [http://reprap.org/bin/view/Main/ThermoplastExtruder_2_0 Thermoplast Extruder Version 2.0]. The principle is exactly the same, but a redesign has condensed the RP parts into one component ([[Mendel materials procurement#Reprapped parts|click here]] for instructions on how to get hold of RepRapped parts). The non-RP parts remain the same, therefore please refer to the [http://reprap.org/bin/view/Main/ThermoplastExtruder_2_0 Thermoplast Extruder Version 2.0] documentation to assemble the non-RP components. The rest of this page will deal with the new assembly only.<br />

<hr />
<div>So what do you need and where do you get the parts?<br />
<br />
Part quantities and suggested suppliers are in the [[media:Mendel-m4-assembly-data-sheet.ods|assembly data sheet]] in [[http://www.openoffice.org/ Open Office format]] on the the '''Bill of Materials (BOM)''' tab. ''Please feel free to upload suggestions for supply, whether you are a supplier or a builder, by adding new columns to the spreadsheet.'' Please ensure your additions are efficient, thorough and fully linked.<br />
<br />
From the BOM you'll see that you need to get hold of about 10 different types of materials. '''Before you buy anything''', here is some important information you should know, including a [[#Costing|cost breakdown]] at the end:<br />
<br />
== Bar ==<br />
<br />
All bar is ø 8 mm diameter.<br />
Generally you can survive just fine on “Bright Zinc Plated" (BZP).<br />
BZP is better than Bright Mild Steel (BMS) as BMS will rust unless coated with oil.<br />
A2 steel will feel nicer and be straighter, but is more expensive. <br />
It is best to buy in 1m lengths and then cut to size.<br />
See the [[media:Mendel-m4-assembly-data-sheet.ods|assembly data sheet]] for the number of 1m lengths needed.<br />
<br />
== Bearings ==<br />
<br />
Mendel does not impart big loads on any of the bearings, therefore high specification bearings are not at all needed. Get the cheapest ones you can.<br />
<br />
== Belt ==<br />
<br />
Make sure you get a Contitech Synchroflex tooth profile, or an equivalent, which allows enough room for chunky teeth. For example, HTD (round profile) does not allow enough room for teeth on a tight diameter.<br />
<br />
RepRap attempts to print its own parts wherever possible. This includes toothed drive pulleys. 5 mm pitch (or imperial equivalent XL pitch, 0.2") belts have been investigated because at the time of research a 5 mm pitch was the most achievable to print. See the [[media:Mendel-m4-assembly-data-sheet.ods|assembly data sheet]] for the belt specifications.<br />
<br />
Belt need to be split to a width of 5mm. This can be achieved using the [[Belt splitter jig]] (two reprapped parts).<br />
<br />
== Extruder parts ==<br />
<br />
The extruder design is frequently updated: check the [[Mendel extruder|Mendel extruder page]] for the latest procurement/preparation documentation.<br />
<br />
== Fasteners ==<br />
<br />
Cheap BZP parts are fine.<br />
<br />
== Motors ==<br />
<br />
Mendel has been designed to cater for either NEMA 17 or NEMA 14 specification stepper motors. Buy whichever is easier and cheaper for you. If going for the smaller NEMA 14 motors, aim for the high torque option. You need approximately 1400 g.cm of holding torque or more to be safe.<br />
<br />
== PCB/Electronics ==<br />
<br />
You’ll need a fully assembled electronics kit (the assembly directions here support [http://dev.www.reprap.org/bin/view/Main/Generation3Electronics Generation 3 electronics]). You can buy these ready assembled, or as a kit that you can [http://dev.www.reprap.org/bin/view/Main/HotplateReflowTechnique solder up yourself].<br />
<br />
== Thin sheet ==<br />
<br />
This is needed for the optoswitch flags. <br />
Thickness must be less than 2 mm.<br />
You will need a minimum total area of 8 cm x 5 cm.<br />
Material must be opaque to infra-red light (the optoswitch uses IR light).<br />
Material must be pliable (easy to bend into shape).<br />
Aluminium sheet is good. Some New Zealanders have been known to use beer cans, which are easy to cut with ordinary scissors...<br />
<br />
== Reprapped parts ==<br />
<br />
[[Image:total-build-in-440x440-envelope.PNG|thumb|Mendel's reprapped parts]]<br />
<br />
You need to get hold of a set of reprapped parts. Many people will be upgrading to Mendel from RepRap Version I "Darwin". Darwin can print all Mendel's parts. So can all the commercial RepRap-derived machines available from the suppliers on the [http://reprap.org/bin/view/Main/PartsSupplies Get-a-RepRap-Kit page]. There is a [http://dev.forums.reprap.org/list.php?94 page on the RepRap forums] where people offer reprapped parts for sale, and [http://dev.forums.reprap.org/list.php?95 another forum page where people post wanted notices]. Finally, if you know someone with a RepRap who could print the parts for you, offer them some beer...<br />

<br />
A small list of commercial Rapid Prototyping Services is [http://reprap.org/bin/view/Main/PartsSupplies here], but be warned, RP bureaus generally charge extortionate rates.<br />
<br />
== Thick Sheet ==<br />
<br />
Sheet must range between 4 mm - 6 mm thickness.<br />
You will need a minimum total area of 42 cm x 40 cm.<br />
'''Your sheet must be flat as this is what you’ll be printing on!''' <br />
MDF (Medium Density Fibre Board) is definitely best as it laser cuts or saws easily and is usually very flat. It is also cheap.<br />
Plywood is a good option if you require extra strength in your machine, but is harder to work with, either with a saw or a laser cutter.<br />
If using polymer make sure it is flat. Cast polymer is the flattest, but may not laser cut as well as extruded polymer. However, extruded polymer is typically not flat.<br />
When storing sheets always store them face down on a flat surface. Stacking them at an angle on their side will ruin their flatness.<br />
<br />
== Studding ==<br />
<br />
All studding (''i.e.'' threaded rod) is M8. <br />
BZP is fine.<br />
It is best to buy in 1m lengths and then cut to size. <br />
See the [[media:Mendel-m4-assembly-data-sheet.ods|assembly data sheet]] for required lengths.<br />

<br />
The machine on the right is the RepRap printer, which we lovingly call "Mendel". It's the second, new-improved version: small enough to fit on your desk but with a print volume large enough for you to make big things (see [[#Mendel specifications|specifications below]]). The machine is made up of bits bought in from local suppliers, and parts which it has made itself - all the translucent structural components.<br />
<br />
In the picture, behind the machine, you can see the RepRap software which you can use to print [www.thingieverse.com your thing]. We give this, and the designs for the machine away, free - it's all open source. Though you do have to buy in some standard components from... well, whoever you want... which can cost up to £395. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.<br />

== Mendel vs. Darwin ==<br />
<br />
Mendel is the latest generation RepRap machine. Mendel supercedes the first version, which we call Darwin. [http://dev.www.reprap.org/bin/view/Main/RepRapOneDarwin For RepRap Version I "Darwin" instructions follow this link.]<br />
<br />
Mendel has the following key improvements over Darwin:<br />
<br />
* Bigger print area, smaller machine footprint<br />
* Improved constraint on the z-axis to eliminate jamming<br />
* Better axis efficiency<br />
* Simpler assembly<br />
* Capacity of tool changing<br />
<br />
This video illustrates these improvements:<br />
