So I’m slowly building up all of the parts to build my MPCNC without making the wife angry and decided to start on the electronics. I have my Mega, ramps, motors and stepper controllers all hooked up and flashed with the Marlin software of this page. When I hook it up to either Ponterface or Repetier-Host, I can only get the z axis and extruder axis to move. I’ve switched out the motors / stepper drivers from x/y to the z channel on the RAMPS and they work so there isn’t anything wrong with that. In either Ponterface or Repetier, when I hit x home, I get a buzz from the stepper motor, but no movement. I adjusted my voltage on the drivers to 1.4 (prior to powering everything up), and when the z axis is moving, the driver gets warm but not too hot that I can’t touch it. Motor gets a little warm but not too bad.
Yes, I have the 100k ohm resistor in the D0
Any ideas what I’m doing wrong? I’ve attached 2 pics of my setup so far:
