Z-axis “activation”.
I using a fork of grbl-mega RAMPS 1.4 for the Makeblock megaPi (mega 2560). I have added a z-axis and despite enabling the z-axis in laserweb4 the z-axis does not “Home” although manual control is fine. What am I missing?

Thanks,
Ron

May be, your firmware has not activate the homing for the 3 axis.
What about your z homing switch. Exist? It is no or nc? If nothing is installed, the firmware think that z is at home because z switch nc is activate.

@Roberbike Oops. No limit switch installed. Thanks.
