+##How do i invert an axis or both axis
+
+if you want to reverse the axis just put an addition negative sign there in the Postprocessor:
+You need to do it on all positions where you find X and I values if you want to switch the X axis only. If you want to do it for the Y Axis do it for Y and J also. Therefor you need to change the followowing 4 lines to the following:

Nice tool.
Linux CNC (EMC2) need O{number} in front of the IF command in the G-Code.
In my postprocessor file:
O??? IF [#<_spindle_on> EQ 0]%nl M3 M8 G4 P2%nlO??? ENDIF%nlG1 Z%ZE%nl
Instead of ??? I need an ascending number.
Eg O101. Output must be:
O101 IF [#<_spindle_on> EQ 0]
M3 M8 G4 P2
O101 ENDIF
Is there a variable I can use there?
