As it runs, the 800 or 1000 divisor seems to be the smoothest, either one getting to 2500+ revs, 800 stalling, 1000 dieing because of slow opto's at about 220 kilohertz. Either way plenty of turn the house around torque, so I'm suitably impressed. Now I need a 10mm belt pulley with 30 teeth and a motor mount for a nema 23. The trick is finding both on this side of the pond... Thanks All > That 8 lead nema 24 on the x is slow, stalls at > about 30 ipm. even when set as 4 wire parallel and all the amps a > 2m542 can do.
