By pass IHC code

1

Is there a way to bypass the IHC code on a “ready to Cut” file if you only have the original Crossfire table.

Yes, but it’ll involve editing the G-code.

Are you running FireControl or Mach3 on your OG Crossfire? It’ll determine the changes.

Ok, Here’s a chunk of IHS / THC enabled code with needed changes noted. Note - If there are multiple profiles, you’ll need to do this for each profile.

(v1.6-af)
G90 G94
G17
G20
H0 <— Disables THC - Delete this line

(2D Profile3)
G0 X2.9202 Y19.615
G92 Z0. <— Start of IHS Probing - Delete
G38.2 Z-5. F100. <— IHS Probing - Delete
G38.4 Z0.5 F20. <— IHS Probing - Delete
G92 Z0. <— IHS Reset - Delete
G0 Z0.005 (IHS Springback + Backlash) <— IHS Springback / Backlash - Delete
G92 Z0. <— IHS Reset - Delete
G0 Z0.145 (Pierce Height) <— Peirce Height - Delete
M3 <— Torch On - Keep
G4 P1. <— Pierce Delay - Keep
G0 Z0.055 (Cut Height) <— Drop to Cut Height - Delete
H1 <— Enable THC - Delete
G1 Y19.465 F30. <— Start of Cut … Until Below

(End of Profile)
G1 Y19.565
H0 <— THC Disable - Delete
M5 <— Torch Off - Keep
G0 Z1. <— Raise Z - Delete

There may be one profile, or dozens. As long as you remove the IHS / THC commands (assuming OG 2x2 Crossfire without Z axis), it should run fine. Remember, you’ll need to establish cut height with your gauges (the black ones) prior to starting the program.

My example is based on code generated by Fusion. SheetCAM should have similar code. If not, please post and we’ll take a look.

Be aware - If the code you have was generated without THC, You probably won’t have the H0 or H1 commands. Just delete if present.

When you download the file from Fireshare, there is a box at the bottom that you can check to remove IHS commands from the file.
