				How to zero out "z" value on Ruida 6445s

I would like to zero out the z value(in the attached photo,"2862.4mm")at the highest  position.  Any suggestions on how to do this?  I have a
Ruida 6445s controller and Lightburn.  Many thanks, Mark

				I think that 3000 appears when there is no limit switch [ when you home for instance ]- so I would guess a pushbutton hooked to the controller's Z limit terminal 'may' do it? On the other hand... I am often wrong.

				I should add that I have a working limit switch on the top and bottom of the desired movement.

				Is home enabled in the controller for Z? It is off by default in most models.

				Dave, thank you for the suggestion. Your comment led me to look for the following.  I changed the setting in Lightburn to: edit menu>machine settings>z axis settings>enable homing>true .  That did it.
