I posted this on the ramps forum and got no response. I have run the ramps test program and everything works fine, yet after I loaded up Repetier firmware and connected to the printer with Pronterface, the z motors didn't respond. I then attached one z motor to the x stepper driver and the other to the y and the motors worked. When I connected the x or y motor to the either z stepper driver pins , they don't work. Ramps 1.4 mega r3. The x and y axis home. M119 returns x_min:L y_min:H z_min:H z_max:H as the status of my end stops. Is it a software problem?
