Ref all Home
« on: April 20, 2008, 03:00:14 AM »
When I ref all home, the x and y axis move to the home switch a back off a small distance which is noticeable.
The Z axis moves to the home switch but there is no visible back off.

Is this normal?

Thanks Mike

Also have a look at the Z DRO - does it move. It could be you have backlash in your Z axis, and the movement is taken up by this. Cut down the speed of the homing, and this will make it clear what moves where - it might be better to cut of the auto-zero as well while you check it out.
Not me driving the engine - I'm better looking.
