Re: Stepper motor locks up when going higher than 8mm/s
Put a 200 teeth GT2 pulley (can be found on this forum) on the motor, a 20 teeth on the M8 screw, a closed GT2 belt, high temp lithium based lubricant for the M8 "et voila" !

The A4982SLPT is an improved version of the A4988 stepper motor controller driver chip. The advantage to this chip is a larger package for heat dissipation. Note: This driver does not allow 1/8 micro...

The A4982SLPT like its predecessor the A4988 are constant current devices. Does this mean that If I upgrade the Supply Power Supply from 12 to 24 VDC that I will not have to readjust the V-Ref voltage...

Okay so for my understanding, would the short wiring diagram be correct? Do I need different drivers to power Unipolar motor in unipolar mode rather than bipolar? [attachment 109585 unipolarbipolar.jpg]
