G0 Z-10.
G98 G82 X0. Y0. Z-2.65 R-15.25 P0.06 F56.
G91: incremental mode,
G0 Z-10 .: Z moves down 10mm = absolute Z=29
G98 G82 X0. Y0. Z-2.65 R-15.25 P0.06 F56 .: Z moves with rapid traverse to absolute Z=-15.25 through the workpiece and drills up with F=56 to absoulte Z=-2.65.
Correct would be: Z drive down 15.25mm and drill 2.65mm deep.
G82 values are not interpreted incrementally.
Information about G82 in the Mill GCode Programming.pdf page 57, 60 in the Docs folder.
Is it due to mach4 or the csmio controller?
