Hi there, I am using screen set 2010 and running windows 7, so far until today everything was fine, but now when I do the Z axis quick zero the z as goes down touches the touch plate, then it goes up and comes down again touches the plate but it does not go up instead a pop up screen comes up and it says "Z clearance plane is above z axis home switch   press OK or cancel, I have checked all the setting but I have no idea what they are supposed to be or where to find them, does anyone put there have any ideas as to solving this problem ?

Regards

I'm just learning this screen set too but have seen this, It has something to do with the Z clearance plane setting and the position of the z when it touches the plate, is the material or part much thicker than usual?

I think its triggered when the z touch is higher than the setting in clearance plane box in settings tab.

It is trying to lift the Z to the clearance plane position but the distance left in z travel is less than the setting height - so you get "Z clearance plane is above z axis home switch"

My z axis home is at the top which in my setup is machine co-ord Zero, my clearance plane is 60mm and the message pops up if the height sensed does not leave at least 60mm above the part.

Thanks for the reply Daveko, I just played around with some  of the settings and it is working fine now.
