The heated be I bought from Think3DPrint3D won't fit between the bolt heads holding the bed to its chassis. So I've ordered some countersunk screws to repleace the hex headed ones.by MichaelShillabeer - Reprappers

Extruder completed and wired to RAMPS Heater reaching operating temperature and thermistor reading ok. Nearly complete! Need to fit heated bed and get a piece of glass. End stops need checking too. X and Y don't stop carriage from moving. Z does.by MichaelShillabeer - Reprappers
The extruder is nearly complete. My resistor is smaller than the hole in the heater block, so I've made a brass wrapper using an offcut of brass from an etched model railway kit. The wrapper doesn't completely surround the resistor incase of expansion. Has anybody connected the resistor to the two threaded bars? 1: as a physical support and 2: as a power sourceby MichaelShillabeer - Reprappers
It won't be working by the 2nd just found I forgotten to buy fire cement and kapton tape for the hot end! The thermistor I bought won't fit into the 1.5mm hole in the heater block. Michaelby MichaelShillabeer - Reprappers
I didn't receive a response to my question about cutting the belt, so went ahead and cut it with no adverse effects. Progress has been positive with the RAMPS and Arduino fitted. Stepper motors and end stops wired to RAMPS. I've installed Tonokip firmware and have got the X, Y and Z axis all moving using Printrun I've tried using the newer Marlin firmware with Printrun but get "Error:0 : Extby MichaelShillabeer - Reprappers
Its nearly a year since I last posted and I still haven't finished... In my defence I have built a T gauge model railway which won Hornby Magazine's 3 foot challenge Prior to that I did do some work on my Mendel RAMPS board assembled Stepper motor and belt installed on x axis X and Y axes fitted to frame I'm eager to finish the project now - I want to print a model railway viaduct. Just reaby MichaelShillabeer - Reprappers
Closer examination of the PCBs that I purchased shows that one of them is a mirror image of what I think it should be! The PCB is etched so that all components fit onto the track side. I'd planned to fit the sockets for the Pololus onto the track side as per the photo on the RepRap website but don't want to fit everything like this. So I'm going back to my original RAMPS plan and have orderedby MichaelShillabeer - Reprappers
I'm working away from home this week, so packed my box of RepRap parts. Last night in the hotel I assembled three opto endstops. I drilled the PCBs, cut the PCBs to size and soldered all the components. Tonight I plan to work on the Pololu PCBs.by MichaelShillabeer - Reprappers
This afternoon I've: Assembled the Z Axis Lead Screws Fitted an Optoswitch Mount Fitted Idler Pulleys to the lead screw bases I trimed the spring so that it is flush with the optoswitch mount. The washers for the idler pulleys needed a flat filing so that they would fit next to each other. Photos of the above are on Flickr Two different sizes of drive pulley are in my kit. Which size should Iby MichaelShillabeer - Reprappers
I completed a few tasks over the weekend: Thread locked the A frame Completed the Y Axis Chassis Completed the Y Axis Idler Bracket Started the Y Axis Motor Mount To avoid confusion as to what has already been locked with thread lock, I marked each locked nut with a drop of ink. This was suggested by colleague (Tom Lee) who's building a RepRap. The penny washers I'm using needed a flat filing sby MichaelShillabeer - Reprappers
I went to Adrian's talk in Bath last night and saw working RepRaps for the first time! Adrian's talk and seeing RepRaps in action has inspired me to get mine working... In the meantime, some more components have arrived: Single row header sockets for the Pololu stepper drivers from Spiratronics Right angled SIL header plugs for the Pololu stepper drivers from Rich Electronics MOSFETS, resisby MichaelShillabeer - Reprappers
hello I saw this on the Register this morning: Printable Transistors How long before printing an MCU? Best regards Michaelby MichaelShillabeer - General
Its been a while since I posted here or done anything on my RepRap. I've moved house and RepRap now has its own desk space. However, I've bought some more parts too: Extruder HotEnd Set from the_reprap_kit_store PCBs for opto endstops and Adrian's cooler running Pololu from WolfSigns Custom Stickers&Clothing - please note that these PCBs aren't drilled or cut to size Resistors, capacitoby MichaelShillabeer - Reprappers
My Mendel has been on hold while I completed some model railway projects for a competiton. However, I've taken the components into work for lunchtime assembly :-) Y Bearing 180s assembled today.by MichaelShillabeer - Reprappers
Is the meet still going to happen? Thanks Michaelby MichaelShillabeer - West of England RUG
Progress continues - more photos on Flickr All X axis components assembled and Y axis started - very fiddly putting the washers and bearings into the recess in the Y Bearing 360 - see photo I haven't read all the instructions ahead of time... found that I've got the new X axis motor mount and that the screws I have are too long. Shorter ones ordered. Also found that I need some grub screws tooby MichaelShillabeer - Reprappers
hello I've just ordered an insert from Maritime Models It cost £3.19 including postage and packing. Michaelby MichaelShillabeer - General Mendel Topics
Started assembling the X axis this weekend - more photos on Flickr I inadvertantly used lock nuts for the caged nuts but can't see this being a problem. I mis-folded one of the thin sheets the wrong way, so the subsequent re-fold is a little weak. These end stop sensors seem a little feeble compared to the rest of the design.by MichaelShillabeer - Reprappers
Pololu Stepper drivers received. Thick and thin sheet order from The RepRap Kit Store Plus I've assembled the framework - see some pictures on my Flickr site. Next stage is to square the axes, check the dimensions and apply threadlock to the nuts.by MichaelShillabeer - Reprappers
Sadly no actual progress this week but found some Pololu Stepper Drivers in stock in the UK at SK Pang so got an order in quickly! Just had an email to confirm dispatch.by MichaelShillabeer - Reprappers
oops, forgot that 'P' in RAMPS is for Pololu Got my Arduino Mega though :-) Everywhere seems to have the Pololu's on back order though :-( None in stock on Pololu's website. Is there any stock in the UK? This is why I was looking at alternatives. If I go this route I'll think of a new board name.by MichaelShillabeer - Reprappers
Thanks Cefiar and Rich. RAMPS is clearer in my mind now. Bought an iron from Argos for £4.49 at the weekend for toner transfer. I've done some more thinking about RAMPS. Investigated stepper motor drivers and looked at: * DRV8821 - 1/8th step 1.5A drive two motor drives * DRV8824 - 1/32nd step 1.6A output single motor drive * DRV8811 - 1/8th step 2.5A output single motor drive The stepper motorby MichaelShillabeer - Reprappers
I've got the Arduino Mega now and have purchased a Maplin pcb etching kit to make a RAMPS. I've been thinking about how to use a single sided pcb. The connectors between the boards require the copper side of the pcb to be on the outside of the Arduion / RAMPS sandwich which puts the components on the inside which is not good for cooling the stepper drivers. Putting the copper side on the insidby MichaelShillabeer - Reprappers
Not much Mendel time this weekend :-( However, cut some more rod and had a think about the electronics. I considered Gen 3 and Gen 6, but dismissed them because I'd like to do some assembly and these appear to be virtually all surface mount components and I'm put off by the component size! I've settled on buying a Arduino Mega from D-Robotics and building a RAMPS circuit to interface the Mendeby MichaelShillabeer - Reprappers
Hello After seeing a commercial 3D print at work I went searching for info about them. I found RepRaps on eBay and decided to build one. So far I've purchased: * Stainless steel bar bought cut to size from The Metal Factory * Nuts, screws and washers came from Screwfix, Toolstation and Boltbase * Bearings from Thing Farm * Belts from Belting Online * Stepper motors from Zapp Automation * Studdby MichaelShillabeer - Reprappers
