The drive goes up to 80v, so if you could reduce your 90v drive voltage, to something like 75, it should workout well -Dane -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

I see the above reprap SCARA being a positive and constructive engineering use for a reprap machine. The HF06 used stepper motor and linear bearings but the rest is pretty much made with a reprap.

(no linear bearings) That platform (video) looks really far along. One of the mechanisms IBM used in this arm to maintain constant direction on the front facing appendage is just link it with a belt to the theta 1 axis. it effectively removes the 'turn' on the front axis, so you don't necessarily have to have the extruder (or pen) in the video's case in the exact center of the front facing part. I can snag a picture later on to demo this, which might be useful for printed-out-scara-arms. @jeshua, thanks! The smiley-face was a reference to the movie 'moon'. There's a robot in the film with a very basic display, that looks similar to the printout.

[Emc-users] SCARA robot arm 3D printer
Hi o I just went through integrating EMC2 for a 3d ABS/PLA printer Its detailed here: transistor-man.com/3dprintbot.html The control boards have their source files and pcbs listed, i;m working on pushing the schematics up this week. I ended up doing exactly what was suggested earlier in a previous thread, having MCodes call extrusion or heating, and that's about it. I didnt end up purchasing / going with the reprap/makerbot control boards as i didn't need the complexity. Overall it was simple but took many weeks to get up to speed, learn the innerworkings of emc2, and get stepgen to work with nontrivial kinematics. As the printer is a SCARA arm, the kinematics and setup make it quite a bit more difficult to calibrate, which also took a bit of time to work through. If there are any questions shoot over an email, hopefully the documentation will be helpful for those few folks working with non-cartesian platforms (scara / kuka) -Dane transis...@transistor-man.com -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
