Initial setup and I'm trying to home the machine. Pressing the home switch in Grbl starts moving the Z Axis up but it never recognizes the switch - it reaches the top and just stops and errors so it never moves on the home the X and Y. I've double checked the documentation and also the wires - everything looks good. I also saw the other thread where it was suggested to switch the Z Homing connection to the other port a few slots down with no success. Movement along all axis' otherwise works fine.

So you can jog the motors in XYZ directions but you can't home?
Does the Z axis crash (start making a grinding noise) before hitting the limit switch?

No it crashes after hitting the switch and jamming against the top bracket of the axis- I think I'm going to try lowering the switch a tad.

Ok - that fixed it - when I looked close the switch looked a little pinched.

I am having a similiar issue. When running the $H command the router does not recognize the Z home switch and keeps trying to go up then doesn't allow the router to go on to the x and y axis. I tested the output for the z+ and z- end stops on the board and got 0 voltage. All of the other switches are recognized through the gcode platform. Any suggestions?

Zavior - in my case all I had to do was move the switch down about an 1/4th of an inch. It just didn't have enough room to activate.

I was able to figure it out. For some reason I had to move the Z homing switch to the SpnEn slot and the GCode Platform was able to recognize it. Why? I'm not sure 🤔 Would love an explanation though.

You have a laser on your order, so the board is set up for a laser. This requires the pin labeled Z to have to be used for PWM control for the laser. The laser setup instructions cover that, but maybe you haven’t gotten to that yet.

Ahhhh okay got it. That would explain it. I haven't got to setup the laser yet. Thanks for clearing that up!
