I have 4-axis 6090 CNC from china,
i am using "G-Code-Ripper" to work with uneven surface copper pcb.
but when i run the file.ngc file in mach3 the output in the file gives similar values for each axis,
though while running the probing it shows proper Z values on Mach3 interface.

the output file looks like this
"
54.97500,21.67500,-0.03750
54.97500,21.67500,-0.03750
