OK, trying Fusion CAM. Here are my sheetcam settings for 18ga steel. I spent several hours tweaking these for optimal cutting.
Set up a F360 plasma cutting tool
I don’t see a place to set plunge rate but I have feedrates, cut/pierce height and pierce time set.
Here’s F360 post dialog
Cut height, pierce delay, pierce height are wrong. Do these not flow through from the tool settings?

in the cps v1.6 file, I see the post properties are statically defined.
properties = {
ihsToggle: true,
thcToggle: true,
pierceDelay: 0.5, // specifies the delay to pierce in seconds
pierceHeight: 0.15, // specifies the pierce height
cutHeight: 0.063, // toggle between using G0 or G1 with a high Feedrate for rapid movements
retractHeight: 1, // the retract distance
ihsSpringback: 0.020,
};
I’ve spent hours tweaking my sheetcam tool settings to improve dimension accuracy, kerf, minimize dross and pierce hole size. I don’t see how using Fusion’s CAM/post gives me the tool flexibility of sheetcam. Especially when all the sheetcam values I tweaked are statically coded in the LS post cps file and have to be changed every job. If I’m missing something here, please let me know.
