I expect modern ones might have more torque though due to better magnets.<br /><br />I expect these will drive a screw drive extruder, and pinch wheel with some gearing.<br /><br />I wanted a Nascom at the time, but my pocket money and paper round wages were not enough!nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-6114545237966583702009-04-14T03:43:00.000+01:002009-04-14T03:43:00.000+01:00Both the 4 wire steppers I have with splined shaft...Both the 4 wire steppers I have with splined shafts were recoverd from 5.25 hard drives 10MB also Shugart SA465 5.25 floppy (1978) from Nascom1/Map80 this had a bipolar 6 wire stepper I'd put them to one side after reading your extrusion torque experiments.<br />Are you sugesting in your post that steppers like this could be capable of driving an ABS extruder ? <br /><br />http://www.nascomhomepage.com/<br />http://en.wikipedia.org/wiki/NascomAnonymoushttps://www.blogger.com/profile/11790019375326311849noreply@blogger.com
