I have an Open Builds Nema 23 High Torque that stalls/skips steps once it reaches ~450 rpm. Is this normal? Perhaps I'm reaching a resonance frequency? Perhaps this is too fast for the stepper? I'm running a 24V power supply and Buildbotics controller. I've run it moving a load via a belt and also free to spin and it always stalls around 450 rpm. Acceleration and jerk settings don't influence the RPM at which the motor stalls. I'm using the motor to move an XL Gantry cart back and forth on CBeam for a lightweight, high speed application (not machining) I get up to 26m/min. Any insight would be appreciated as I'd like to figure out if a different motor may help me speed things up. Thanks!
