So I just got all new controllers and new motors. the motors are 425 oz each nema 23 that use 4.2 amps. The controllers are selectable and I have them set on 4.2A and each 2 out of 4 are connected to a 48 v power supply. So yes, two power supplies. So I set the motor tuning at 2000mm per min with accelartion of 200. If you run any motor x,y,z (y has 2 motors) it seems fine. The motors sound great and move very nice.
But, when I run a test g code and everything starts running at once, I start losing steps and the motors start making noise.
Any ideas ????? Thanks Steven
