I’m building a MPCNC and I’m at the electronics part now but I’m having problems with the motors. They only move when I do it in 0.1mm increments but not in 1mm and 10mm increments, in that case they make a whining noise but do not move at all. Also, if I send a lot of 0.1mm steps at a time, it will do the same thing, noise and no movement.
Can someone please help me?
My drivers are DRV8825 with NEMA 17 (17HS19-2004S) motors and Mega 2560 R3 + RAMPS 1.4 running “Marlin RC7 MPCNC w/LCD”. I can send pictures if you guys need. Also, I’m running a 5A 12V power supply.
