Hello,

I have made my own 3-axis engraving machine from scratch and have everything running well, but I need help with the Z-axis setup. I have only used the ports/pins and the homing/limits to set the direction and homing. I want to set z-axis home to the up position but the co-ordinates are working in reverse. How do I setup the z-axis ?.

Cheers,
Brett.

Do you want to reverse the direction it's moving? If so, check "Reverse" in the Homing/Limits page.

Hi Gerry,

Zeroing the z-axis to the bottom switch would seem the way to go, but when I have a tool in the spindle it will hit the machine table before the bottom limit switch !. My problem is more about how the z-axis needs to be setup more than how to reverse settings.

Cheers,
Brett.

Typically you home the Z to the top of it's travel, and zero it to the surface of the part before running your programs. You might want to look into making an Auto Zero device.
