Hi, we tried to modify our k40 with a smoothieboard 5 v1.1. We connected the steppers accordingly to the guide (AABB). We calculated the steps per mm with an online calculator. When we connect the board I am able to move the X(alpha) motor left and right but with A LOT of vibrating and it also gets hot. When I try to home it it moves to the right and stops at around the middle (endstop is on the left) even tho when I press X- and X+ its the right direction. When I try to move the other motor it stutters and doesn‘t move. I tried changing the steps per mm but it doesnt seem to change anything?
When connecting the M2-Nano again everything works fine.
Any help would be appreciated.
