I’ve just finished my build and started testing, having issues with the E0/X2 driver port.
RAMBo v1.4 board from V1
V1CNC_Rambo_Dual firmware from V1
Full Graphic LCD Controller from V1
Dual endstop wiring kit from V1
NEMA 17 Steppers from SteppersOnline PN:17HS19-2004S1
It seems that the E0/X2 driver on the board is not working properly. All of the other drivers are running steppers smoothly and consistently. When a stepper is plugged into the E0/X2 driver port the shaft shakes back and forth not moving and makes a loud noise that the others do not. I have tried multiple steppers plugged into this port and they all do the same thing, when plugged into different driver ports they work fine. I flashed the board with the V1CNC_Rambo_Dual firmware. I’m testing manually from the LCD and the crown file off an SD card currently, I have the X belts removed as I did not want to rack the frame. With the belts connected the side with E0/X2 would drag along with the stepper on the other side and shake the axis. Not sure if this is software/settings related or a bad board.
Please advise on how to proceed as I don’t want to ruin anything.
