Hi Guys,
I'm currently having issues with my z-axis movements. To set the scene, I am using a Azteeg X1 board, running repetier firmware (adjusted to suit Azteeg boards) and interfacing using Repetier-Host for mac. For some strange reason, all my axis work in both + and - directions except the z axis. It will only move in the positive direction, ignoring any commands in the negative direction. I have tried swapping the stepper driver boards, but no change to either axis. I have re-uploaded the firmware, no change. I have tested the steppers on other axis sockets to verify the wiring/motors are ok and they perform fine. I have checked the DIR pin on the stepper driver board and it switches from low to high and back to low as required, but will not produce motor movement when fed a negative z axis command. I assume the steppers are connected correctly as i get movement when plugged into other sockets. I have tried manually jogging the motors using g-code commands but no change was noted. I have tried running a test piece, but no change was noted. Any ideas?? I'm completely lost for direction atm and really hoping it isnt an issue with the board. Is there any way I can test the board to confirm there is no issues?
Thanks for your help,
Scott
