That is excellent, I didn't realize it, bit you're correct, there are fewer non-printable parts on a scara versus a conventional XY platform. (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. I think this is the most-recent for scara-reprap development: http://forums.reprap.org/read.php?2,128991,128991 if you run into other people developing for that platform i'd be curious, Thanks, -Dane ------------------------------------------------------------------------------ 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. Discussions will include endpoint security, mobile security and the latest in malware threats. http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
