I just finished my CrossFire Pro table setup today, using the Thermal Dynamics Cutmaster 42 I’ve owned for a while. I discovered that the first time the torch was turned on in a toolpath that the arc takes several seconds longer to engage, I suspect as a safety measure to ensure the air is firmly running and cooling the torch before allowing the arc, as the air stays on for ~15 seconds after the arc stops and during the time it will restart immediately.
Since there didn’t appear to be an option for this in the Fusion 360 post-processor I took a look and noticed that the post processors are in javascript, so I modified it to add a setting for this initial pierce delay. As a note: *** USE AT YOUR OWN RISK ***, I accept no liability if this doesn’t work right for you. This is modified from the 1.6 version of the post-processor for the PRO or others with THC.
Here’s the diff, its a pretty limited change. I’ve also attached the modified version to this post.
