Enable Z axix not working

I have Enable Z axix turned off, but when I Home the machine the Z axis Homes also. Is there another way to turn off the Z axis Homing when using GRBL?

Where do you do this?

The basic controller will normally home on power up. You can turn ‘homing’ off, but that causes havoc elsewhere. I don’t remember any way to disable any single axes.

With grbl you can compile the source and disable the Z axes, but you’d have to reload it to enable it again.

Good luck

Check out this topic from last year. Conclusion on this was that this isn’t something that can be done with a setting in LightBurn or a simple configuration change in GRBL. This has to be done at compile time to enable 2-axis homing.

In the setting menu under Z control it looks like you can enable or disable Z?

Unfortunately the homing behavior for GRBL is compiled into the firmware itself and cannot be changed without rebuilding the firmware itself. It’s doable, but it’s a pain.
