Fusion360 post for Linuxcnc plasma table.

I just finished a small plasma table using Linuxcnc. I have a mill that runs it as well. I am using fusion 360 and there is no post processor for Linuxcnc. Am I missing something? I thought that this was going to be the easiest part. The plasma table works and I have been cutting straight lines by jogging. It has no thc. Does anyone know of a post I can use? Keep in mind I can make the machine just fine but I suck with computers.

I have tried every cutting post in fusion and every one that outputs gcode uses codes that Linux CNC does not understand. They have a milling post that works great with my mill but no plasma post. If I try to use the mill post fusion will not let me. For cutting my options are burny, hypotherm, omax,. And torchmate post processor. I did download sheetcam which has a post for Linuxcnc and got it cutting but the cam in sheetcam sucks badly compared to fusion.

I will try again and check what the codes mean. I have no idea how to program those into Linux CNC. My other option is to write a post processor, but again no idea where to even start.
