I’m using an Arduino board to controll 3 stepper motors via DRV8825 drivers. Drivers are mounted on CNC Shield V3. I’m trying to control the steppers without GRBL, but i somehow don’t get it to work… I found in the internet the pin allocation for the CNC shield (see attachments). I also tried using Robin2’s simple Stepper Program just to test it using the allocated pins(e.g. Pin2&Pin5 for x stepper), but without success… Does anyone have some experience using the CNC Shield without GRBL? Is there something else I have to pay attention to using the CNC Shield?
note: Steppers do work if I flash the arduino with Grbl
