that control should work in "Z"+
looks like you mite be setting your tools wrong
you should be using a tooling ball to define the "Z" zero
then use the tooling ball to find the tool offset
ether use an indicator or gage block
find the ball "Z" height
then the tool "Z" height
subtract the two ,this will give you the offset
if the tool is shorter then the ball the offset will have a negative sign
if the tool is longer then the ball the offset will have a positive sign
if the tool offset is longer or shorter then the "Z" travel the control will give you an error |
