        <title>VIDEO POSTED! Details about the BerryBot3D</title>
        <description>First off a special thanks to:
John and Steve, SeeMeCNC (http://shop.seemecnc.com/)
Johann (http://reprap.org/wiki/Rostock)
Zack, Inventables (https://www.inventables.com/)

The BerryBot3d: 
A one off, designed by Werner Berry 
Platen 14&quot;
Build volume 2460 sq inches.  About 6 times the build volume of the Replicator 2 
Zero lash ball joints fully capable of 50 micron LH prints.
The hot end can be popped off the magnets (disconnected) and reinstalled in less than 15 seconds.  Nice for working on or color changes.
Filament reel mounted on top the top deck out of the way (Horizontally)
A simple minimal part count filament feeder that is mounted with magnets and can be removed in less then 10 seconds.
All aluminum frame designed with maximum cooling of the stepper motors and electronics.
A long cable attached LCD SD card control panel also mounted with magnets removable or mounted in 2 seconds.  I love magnets!
A fully adjustable preload, highly efficient, inexpensive, structural linear rail system. 
A rapid heat 110 volt platen.
Easy micro adjustable top limit switches.

When I was about 6 years old my Mom came back from Switzerland where she was visiting family.  She brought  me back the coolest woodworking tool kit.  I have been building things ever since.  I love building things just like all of you.  I had mastered woodworking and had my own cabinet shop at age 15.  When I was somewhere around 16-17 I purchased a welder and felt like I was reborn!  This new medium to work with was awesome!!  In the past week I have had the same kind of feelings playing with my printer.  I can hardly sleep because I am dreaming all night long about what I can do with this new dimension.
The feature I am most proud of is my magnetic joints, end effector/ hotend.  It does look cool but my main design criteria were to build the most precision I could within a reasonable budget.  When you see how simple this is you will want to give it a go.  The magnetic balls are very very strong http://www.fridgedoor.com/maspd03.html  the cost is around $30 for all twelve.  The beautiful thing is that there is virtually no play and so few parts.  You can get an Idea of how is works watching this video. [url=http://youtu.be/hHdPz895r8g]Watch the BerryBot3D in action[/url]
The scockets at the ends of the carbon fiber are equally simple.  You could make them with a hand drill and ½ ball end mill.  I got these from McMaster Carr: 91259A546   By the way I had some carbon fiber tube left over from RC modeling.  I could have just as well used an inexpensive lightweight aluminum tube.  The magnetic ball rides on a Teflon bearing pad. With 2-3 pounds of force there is almost no measurable friction. Something that I think is important to pay attention to is the positioning of the balls when JB welding them to the aluminum sockets so that they are located naturally north or south on the poles. You can feel the difference it in the way of counter force if they are not in alignment. When you watch it in action you can see that they move so little I am thinking they will last for years. Then the bearing replacement is nothing more than a small Teflon disk I punch out of this material I purchased from McMaster Carr: 76025A333 It’s enough for material for 10 lifetimes! I believe there is nothing that will come close to giving the precision the magnet joints can provide for so little money?
When I get more time I will post some more details pics and video links.
Happy Building!

            <description><![CDATA[ Well it is just a prototype with issues. The base is too big and the effector arms too short. I cant use the whole table radius because of it. If I move the head close to the max radius, one arm is too stretched and I loose precision. Instead of 360mm diameter I can use only 280mm dia with good precision. However it is still a lot of room to print. I will try to use smaller pulleys or go for 1/32 microstepping.<br />
I am not satisfied with the bowden so I have placed the extruder directly on the effector, making much better prints. I have a bulldog xl which is very heavy, but the magnets can still hold the 609 grams effector! Now I work on a new extruder using geared nema11 stepper, something similar to the latest Werners extruder.]]></description>

I did it a couple of years ago for another work not a 3D printer.<br />
<br />
The heating wire is inside a mill in a 6 mm 50x50cm alluminium plate. It is feed with 220 volts and reached over 100 ° C.<br />
The thermocouple, the white wire in the image,  is  inside a hole close to the upper side of plate.<br />
<br />
Of course you need a cnc mill to make it because it is important  that the heating wire is inside a mill to dissipate heat, if you simply glue it it will have a low eficiency, will overheat and burn,<br/>]]></description>

<br />
Hi, your design looks remarkably close to Werner's. Any idea on the dimensions - of the carriage and the effector. Correct me if i say that their arms have been bent at 45 degrees. I plan to make one for myself. I have got the makerslide. Have made a base for myself. I was experimenting with printed effectors but I really want to make one out of aluminium.</div></blockquote>
<br />
My angle is about 39°. First I tried to design the correct arm length to reach the biggest possible radius when moving around the platen. Then I was trying to get the best rod alignment when the head plate is in the middle, this gives you the angle of the bends. I wanted the biggest possible area on the magnets for moving the joints for each direction.]]></description>

            <description><![CDATA[ Hey Werner,<br />
<br />
I was wondering about what you have been working on over the past few months? <br />
<br />
It's been a while since you last posted a video. Any further news/developments with the BerryBot3D? A while ago you mentioned starting a Google Group for people who want to build their own BerryBot. I am looking to build a delta bot and I really want to build a BerryBot3D (:D It would be great if you could let us know what you are up to!<br />
<br />
I am a big fan of your work :)<br />
<br />
Thanks,<br />

            <description><![CDATA[ Hi<br />
I was thinking how to make the bowden shorter without loading too much the print head. I really don`t know how bad it is with hysteresys because I am just designing a berrybot style printer, so I have no experience yet. Just an idea - another stepper could move the extruder in Z axis... not sure if the firmware would support this. This way the bowden could be shorter. Just an idea...]]></description>

One wrinkle with steppers is the electrical specs make a difference and need to be suited to the driver. I'm just guessing but I would think most steppers in the range we're dealing with would probably work with the standard drivers.<br />
<br />
Regarding the mount size difference, I think you will be facing that regardless of the geared stepper you use. I bought two different NEMA 17 versions and while they both have a similar mount pattern, they are quite different from a direct drive NEMA 17 mount pattern. It shouldn't be too big a feat to adapt things to match. If it is a big deal, then find a friend or neighbor who is skilled in that field to help. They will be a helpful future asset to have in your arsenal anyway.]]></description>

            <description><![CDATA[ Hi<br />
<br />
My magnets arrived two days ago from <a href="http://www.supermagnete.com" target="_blank"  rel="nofollow">www.supermagnete.com</a> <br />
They're awesome!<br />
<br />
Regarding geared stepper, I've been considering to order a NEMA14 5:1 [<a href="http://www.omc-stepperonline.com/gear-51-planetary-gearbox-for-nema-14-geared-stepper-motor-p-136.html" target="_blank"  rel="nofollow">www.omc-stepperonline.com</a>]<br />
instead of NEMA11 5:1 [<a href="http://www.omc-stepperonline.com/gear-51-planetary-gearbox-for-nema-11-geared-stepper-motor-p-33.html" target="_blank"  rel="nofollow">www.omc-stepperonline.com</a>]<br />
Both have same declared weight but the second one is slightly shorter that might be better for the mass balance of the end effector. (Not sure if it matters so much)<br />
It is cheaper and has a lot of more torque (more electrical consumption also)<br />
Cons are that the mounting dimensions are not the same.<br />
What do you think?<br />
<br />

            <description><![CDATA[ I agree with Eric I think. I can't be sure since I've never had a Bowden extruder and in fact I'm barely scratching the surface with my one printer build as it is, but it seems like the hysteresis would be an issue.<br />
<br />
Regarding steppers, the 5:1 ratio is similar to the gear ratios folks are getting with their printed gear set drive systems (i.e. Wades extruder), so it seems just right. 10:1 <i>might</i> work but would be on the extreme end and is well outside the envelope of the successful Wades extruder ratios, so unless you are already getting good results as a beginner, then reserve that kind of experimentation for a later theory or something. Anything beyond that, and maybe within that even, will have the torque but not the speed necessary to reliably do filament retracting and un-retracting. And on a Bowden type, you really need some speed to deal with the hysteresis I think.<br />
My direct drive 1:1 cold end doesn't seem to have any problems pushing filament (though I have a few other unrelated problems) with a NEMA 17 stepper. A gear stepper will have more torque than direct drive so I would confidently try a much smaller frame gear reduction stepper if I had the desire. I'd be tempted to even try a NEMA 8 if it helps to bring down weight on a non-Bowden (direct) system. Note that the driver board makes quite a difference on how well the motors perform. For example I have a little CNC engraver I built and at first I tried a cheap 3-axis stepper driver board off eBay. It kind of worked, but didn't have much torque and had other little issues, and after a while it just seemed to get worse so I replaced it with a Gecko driver and that made the first board look horrible in comparison. I have a ramps board &amp; the little Pololu drivers for my 3D printer and it seems to work OK with my NEMA 17 steppers. I haven't done any systematic testing or anything because it seems to work fine so I don't know how it would compare to a Gecko drive, but I suspect it's probably somewhere in-between. It's adequate for the purpose. Just some FYI.<br />
edit to add: I like the idea of the gear reduction for more precision on feeding filament. I'm not sure if that matters significantly compared to variations in filament diameter through a spool, even though my spools seem pretty decent on roundness and diameter. But a gear reduction seems like it would have to perform better. My 1:1 extruder drive spins so slowly it is pretty much holding torque most of it's time. I think it would be better if the motor actually spun a bit.<br />
<br />
Regarding the magnets, I got them from <a href="http://www.magnet4less.com/product_info.php?cPath=1_14&amp;products_id=223" target="_blank"  rel="nofollow">magnet4less.com</a> for about $2.50 each. <a href="https://www.amazingmagnets.com/show-decimal-s500d.aspx" target="_blank"  rel="nofollow">Amazing Magnets</a> has them for about the same price.<br />
 I don't know Gauss from guess so I can't offer any learned opinions about magnet specs.. But I would think any of these Neodymium magnets will have similar strength and be just as effective.<br />
<br />
On a side note of my own, I made a list of the stuff I need to aquire to pull off building one of these printers. I'm also considering a lithographic/resin system for the higher resolution. So I'm still weighing which direction I want to send my efforts and time. I'm a cheap bastage though so I imagine in the end I'll probably build a BerryBot of my own since it will be 1/10 the cost of a resin printer. I'll probably wait for new ideas and plans on resin printers to evolve so the price comes down to a more reasonable point. They've come a long way up in quality and down in cost over the past couple years and I'm guessing that trend will continue pretty dramatically over the next couple years.<br />
<br />
edit to add: I got to digging in my pile o' stuff and I think my decision just became easier. I built my printer about a year and a half ago and bought enough to make three because some friends thought they might want one too and making three is just a little tougher than making one (setup is most of the battle). Well their interest faded. So I just found that I have 10-feet of maker slide and plenty of V-roller kits. I was just looking up that stuff on instructables's page and vaguely remembered maybe having the rollers so decided to review my inventory. That sure makes things cheaper. I also have plenty of regular NEMA 17 steppers for the positioning, some adequate 3/8 o.d. tubing and the magnets and geared steppers I just bought, so my major remaining components are hot and cold ends (probably machine myself), electronics, plates and stuff (definitely machine myself), and... uhhhh... that's just about it isn't it? Looks like I might get this going with less than $100 more investment. Kind of a no-brainer.<br />
Hoarding pays off again.]]></description>

Eric: What would be the proper differential for a geared-stepper motor if it is to be applied to a bowden-style extruder? Would NEMA11's still be enough or would 14's or maybe even 17's be better?

<br />
Hey New, I assume that you plan on using this bowden extruder on the huge BerryBot printer that you were talking about building, am I right? <br />
<br />
Since you said that the distance fro the extruder to the hot end would be about 4.5' to 5' long I really don't think that you should use a bowden extruder. In a bowden cable that long the hysteresis would likely lead to miserable print quality. Since you are going to build a large machine, I recommend that you stick with a direct drive extruder like Werner Berry's that uses a 5:1 geared Nema 11 stepper. The geared Nema 11 is not very heavy and on a large deltabot the added moving mass would not be a problem. Plus, using a direct drive extruder will save you the infinite headache of trying to calibrate a 5' bowden cable ;)<br />
<br />
Werner reported great results using his new compact direct drive extruder. You should also check out his videos on his YouTube channel as I think they will really help you with your build. <br />
<br />

Good Luck!<br />

<br />
There is a trade off between torque and speed. I think vinny is talking about the 5:1 geared Nema 11 steppers that Werner uses for his direct drive 1.75mm extruder. In this case, the 5:1 ratio gives the right balance between torque and speed. A 10:1 ratio would give better torque (more extrusion force) but the max speed would decrease. You just have to find the right balance between torque and speed that suits your application. <br />

            <description><![CDATA[ I just recently stumbled on Mr. Berry's delta design. I make things for a living and I am thoroughly encouraged by the clever ideas. I just dig the heck out of this stuff.<br />
<br />
Who knows if I'll ever build one, but I did build an Ord bot a while back and just recently dug it back out to blow off the dust and attempt to tweak it for success. I think it's very possible that I will eventually steal Werner's ideas and make one for myself. I usually add a few ideas of my own, but this one is already so well thought out that I don't see any obvious things to change or add.<br />

            <description><![CDATA[ Hi Guys,  I am in the process of designing/building a new shop for myself and it is consuming all of my time.  I am thinking it should be done sometime around June if I am lucky.  It is so much fun designing where equipment should be placed, how to run, electrical, air and dust vacuum lines…….  NewKid, sure you can run the E3D no problem!!  Scaling the BerryBot3D to 24” circle should also not be a problem using the all the same components.  By T-Slot I think you are talking about OpenBuild extrusions-linear system?   I love OpenBuild components.  I am building a special use CNC router type machine with all OpenBuild for the linear parts.<br />
Thanks again for the nice comments Guys!  I hope to have another fun video up soon talking about designing and processing parts to be 3D printed, Also talk about a new plugin I wrote called the Berry Nice Start to get a great first layer down.<br />

            <description><![CDATA[ First and foremost thank you for sharing your innovative upgrades to the Delta design. <br />
<br />
You have built a beautiful machine, Werner. <br />
<br />
I was wondering if it is possible to upgrade this current design to utilize the E3D Kraken 4-nozzle hotend for mutiple material/color printing?<br />
<br />
Also, if one was to scale up the BerryBot design to have a build envelop of 18"x24" (DxH) what would need to change besides the print surface and longer pillars? Lastly, is there a difference between using T-Slot versus V-Slot extrusions for the pillars?<br />
<br />
Again, thanks for sharing your innovations and designs with the community. Looking forward to building one of these badboys myself someday. :)-D]]></description>

<br />
Correct, although it seems that two videos have been deleted. I was looking for the video with a more detailed overview of the berrybot unit. Something more helpful towards building one, in addition to the information already posted here.]]></description>
