I have some trouble with my Ramps 1.4 board with dual endstop firmware.
I’m using Arduino Mega clone, Ramps 1.4, DRV8825 and Nema 17 84oz. 12v 25A psu. Vref is set to 0,9V and i do have all jumpers under drivers (1/32 step).
Everything works except Y1 stepper wont move. I suspected a faulty driver or stepper, but both do work if i connect them as X1, X2, Y2, Z…
I have no lcd or endstops yet and all movement is done through Repetier Host. No transistors are touching and i have not shorted anything. All drivers except Y1 are getting warm.
