With a minimal strength the motor will stop and just vibrate (doesnt move until the command its done); I configured the pololu to Vref 0.7 But doesnt have strength.\r\nI tried with 24V too and with 17V with 10 amps power supply if was the current... \r\nSo i dont know whats happening. If you have the configuration of the nema 17 Using gcodesender With \"$$\" command to configure it Pass me it please if its another thing let me know "}}
