Torch is to high

[Hank]

The torch is like 1/2 an inch off the sheet metal. Its like thc works for a small piece then stays 1/2 an inch off the surface. It goes down and touches but raises up to far to cut

Two things to try:

1. Look at the gcode to verify that you have the right settings. If you don’t know how to read it, someone would be happy to look at it to see if it is saying what you meant to say for cut height.
2. Run the test cut height file that @Phillipw made. I am not at my computer so I can’t retrieve the file right now.

Here is a link to a previous post that explains the process to check the cut height.

16ga woes.. need help with getting a clean cut

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…

Btw, how thick is the metal? If it is thicker than 10 gauge, you don’t need to have any “spring back” in the past processor.

Do you use SheetCAM or Fusion 360? I know you have posted before… I just don’t remember.

Double check your cut settings, sometimes a misplaced decimal point can drive a person crazy. I’ve accidentally put 0.6 instead of 0.06 cut height, took me a while to figure it out. It behaved exactly as you described though.
