Dual Z steppers and dual extruder
My machine is a home built cartesian using AtMega 2560 and Ramps1.4 board and dual extruders into a Y/ E3D hotend. Was using Marlin until I upgraded to dual Z steppers and a BLTouch (sadly my second extruder no longer works). Can Repetier firmware be setup to use a stepper expander board with the Ramps 1.4. If so how does one go about configuring the pins for the expander board?
