The torque required from each motor is much less than 1/4 of the single motor design because the friction created by the belt is gone.<br /><br />I would think four NEMA17s would also do the job.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-59556804656462667482009-07-20T15:43:57.191+01:002009-07-20T15:43:57.191+01:00Nice.

I've got a bag and a half of random NEMA 17 and 23 steppers sitting around now from scavanging since starting on my RepRap but it would be great to get some for so cheap for other projects.<br /><br />Anyway, thanks for posting again. It's awesome to read your stuff.<br /><br />DementedDemented Chihuahuahttps://www.blogger.com/profile/01715419261430119998noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-55093843017072845362009-07-20T09:03:03.484+01:002009-07-20T09:03:03.484+01:00Hi Demented,

They look like they are for very old 5.25" floppy disk drives. I have recovered similar ones from TRS80 disk drives, but they had a wheel with a spiral trcak rather than a cyclinder.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-48325389898201712742009-07-20T07:02:08.247+01:002009-07-20T07:02:08.247+01:00I was impatiently waiting for your new blog posts!...I was impatiently waiting for your new blog posts!

I guess I should just stop being lazy and google them.

I've got a repstrap built with everything but wires between the motors and the boards, and I have a bits from bytes extruder which has been giving me some problems in terms of grip. It's nice to see you still have your project going. It's inspiration.Jackhttp://idonthaveawebsite.netnoreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-81465278126621412062009-07-20T01:53:29.965+01:002009-07-20T01:53:29.965+01:00Very nice!

This should simplify things a bit!<br /><br />A few relays and a touch sensor toolhead would allow you to level the bed automatically too, but that would add a fair amount of complexity.<br /><br />WadeWade Bortzhttps://www.blogger.com/profile/10975115541719442270noreply@blogger.com
