Run this gcode file from @Phillipw
cut height test.tap (224 Bytes)
It will go thru the IHS (initial height sensing) and then go to the cut height of 0.060 inches and stop. Measure and see if you are at 0.060 inches. The torch will never fire with this code as it never gets the command to fire.
Here is what the file is:
(v1.6-sc)
G90 G94
G17
G20 (Units: Inches)
H0
G92 Z0.
G38.2 Z-5.0 F100.0
G38.4 Z0.5 F20.0
G92 Z0.0
G0 Z0.02 (IHS Backlash)
G92 Z0.0
G0 Z0.15 (Pierce Height)
G4 P0.5
G1 Z0.06 F100.0 (Cut Height)
M5 M30
(PS100)
Notice it also includes the “springback/Backlash” of 0.02 inches. If you are doing this test on 10 gauge or thicker, you really don’t need any springback so adjust accordingly. You will also notice, this gcode file does not include the M3 (turn torch on) command.
