I'm trying to speed up my axis a bit - well a lot actually, since I cannot move them above 4in per minute at the moment.
Up til now, I thought it might be a mechanical problem with the lathe, but I took the belts off the motors and tried them on their own. I can't get them to spin any faster on their own.
I am running 1/8 step, 1.8 degree, 3 to 1 reduction, 1/10" leadscrew which, I think gives me 48,000 pulses per inch and therefore 192,000 pulses per minute for travel.
The motors are Arc Euro Trade Hybrid Steppers - 220Ncm, 2.5amp 7.5volt - and all in all I am satisfied with them - they are certainly powerful enough to do the job and at £22.95 each are relatively cheap.
They are 8 wire motors - and I have wired them in series.
The $64,000 question is - will they spin any faster if I wire them in parrallel - or is my computer - a Toshiba laptop - just up to its limit (says he looking longingly at the USB driver board just announced).
Anybody any ideas???
