If I run home all it works just fine, if I home just the Z axis it comes half way along the z axis and then lowers to crash the bed! I have the same G1 X54 Y5 code in both macros, why is the Z macro failing.

Hi Dave, no if I just click home Z it goes to the wrong position and crashes the bed, if I hit homeall it does both X and Y correctly and then Z correctly and to the right place, X54 Y5. I have not tried homing Z after homing X and Y individually, I am away from home until Sunday evening now but can try it on my return.

The reason being is that the printer does not know what the bed position is before you home X & Y, so it cannot move the nozzle to the homing position.Quote

Hi Brian,
you cannot home the Z axis before you homed the other axis.

Hi Dave, that is so strange, I am sure I have been able to home just Z in the past but it may be that the other two axis had already been homed without me realising.

Thank you both Daves, it makes sense, one almost needs a safeguard to ensure "home Z" cannot be run before X and Y have been homed. Would it be possible to add code to home Z to check for 0 on both X and Y before homing?
