I recently dusted off this board (version 5b), upgraded grbl to v1.1 and connected everything to my Zen Toolworks 7X7 CNC. The X and Y axis move normally, but I cannot get the Z axis to move. I plugged the X/Y axis from the gshield to the Z stepper motor and it works. If I plug the Z axis from the board into either the X or Y axis motors, those stop working. Seems to be an issue with the Z axis from the gshield. If I turn up the pot, the motor gets louder without moving. I don’t see anything wrong physically, so I am wondering if my settings may be causing the problem (shown below)? Any help would be greatly appreciated!

Good Morning,
I hooked up the gShield to the Arduino Due and followed the setup information from this site:
https://github.com/synthetos/grblShield/wiki/Using-grblShieldI have 3 motors and all work on the X and Y controller ports and none work on the Z port. When I enter a command in Chillipeper like G0X1000 the motor turns for almost a second and stops for X and Y, but when I enter G0Z1000 the controller runs endlessly. I start the Z Motor Current pot all the way counter clockwise and slowly turn it clockwise and hear the fan on the power supply increase indicating its drawing more current. I have verified (several times) that the input from the power supply to the gShield is 24.0Volts etc.
Please advise how to determine if the Z port is bad on this board.
thank you,
Bryan HolockerMay 14, 2018 at 2:00 pm #10987kwlabsMemberI have sent an email to support a day after creating this topic and have yet to hear from anyone. It’s a shame, the gshield is a great board but the lack of support is concerning.
If you get a response to your email, please post it here in case anyone else is looking for help… I will do the same.
June 3, 2018 at 4:18 pm #11008BryanHolockerMemberI have mine working now. I had to go thru all the settings in Chillipepper and create a custom startup script to setup x,y,z mappings and motor settings. for example, my motor 3 was mapped to A axis, not z.
