Hj everybody .
I have a problem as follows :
Normally when exporting code on alphacam, the depth of Z will be a negative value.
My machine takes the working origin of Z on the underside of the workpiece using an automatic tool measuring system.
I want to change the postcode to output a positive Z value depth like the example below.
Example :
Safe level (Z=50)
Rapid down ( Z=30)
Meterial top ////////////////////////////// (Z=25) meterial thick is 25mm
table machine ------------------------- (Z = 0) (Z work position ) "G43 Hxx "

If anyone has experience in this case, please help me. Thank you for your support.

Hi,
you can simply write *(-1) to the output lines . G0 G43 Z[AZ*(-1)] H[T].
I'm not entirely sure if this is what did you want because some of Z values are not only negated.
Can you try to change Z0 of global of the material in the Alphacam to the bottom side?
This is maybe what you want.
