I have the Protoneer RPI-CNC-Board (v2.60) and the CNC bridge for external drivers (v2.01) and want to control three stepper motors of a milling machine. I also use the external driver you suggested. While looking for external drivers while looking for a hardware solution, I came across the school project in this forum. The attached picture-1 shows, among other things, the wiring of the connections DIR to DIR and PUL to STEP. Am I correct if the reverse is the case for my hardware versions?
Does he still correctly connect the “ENABLE” signal between the board and the external driver?
In picture-2, my CNC board can be blessed with the bridge attached. Is the bridge properly aligned?
I would be very grateful if you could help me.
