I purchased a black box to replace my arduino and grbl shield. I am running nema 23 stepper. I installed the box last night and set all the settings and did one test cut and everything was in order. Was a really easy swap and setup. Tonight I wanted to start a full cut. The machine started moving to go to the cut start position and then stopped before it got there. I checked to see that the driver indicators are on. I lower the current and power cycle thee box and they stay on. I then unplugged the motors power cycle again and they are still on. This is for X and both Y motors. Z is fine. Can you please assist.
