Looking for Post Processor

[acourtjester]

I am starting to work with Fusion 360 and need to have a Post Processor for LinuxCNC that will work with my table. Hoping a member has one to share. I did search on the web and there is a site with many other PP that work with Fusion but none listed for LinuxCNC.

Have you tried experimenting with any of them Tom. Maybe a generic one will work. Not sure if your THC is stand alone or not, that would complicate things if it wasn’t I suppose.

I have not advanced that much with Fusion yet. There are 2 Post Processors shown in fusion. I can still use the Post Procsseor in SheetCam that does work with the internal THC (Mesa electronics) I have on my table. But if there is one that somebody has the will work within Fusion directly it would be easier.

Tom - from my personal experience I would recommend sticking with SheetCam for post processing your files, regardless of file origin (Inkscape, LightBurn, Fusion 360, etc.). It has been my experience that the Fusion 360 CAM module works well for simple parts, but for more complex parts it can sometimes take "forever and a day" to get the tool paths generated. I have always suspected that the server power offered to those using the free Fusion 360 version is not up to par with that offered to the paid users. Just a theory.

SheetCam, on the other hand, runs "off-line" and only depends on the inherent computing power of your pc.

What you might do is to us a test drawing part - say a square with a hole in the center - and create your g-code using both your SheetCam post processor and one of the Fusion 360 generic post processors and compare the code line-by-line. If there are some special instructions required for your linuxcnc controller, then perhaps modify one of the generic Fusion 360 post processors to meed your particular requirements.

My thoughts exactly, I was going to do that today, with the LinuxCNC PP I use and the GUI QTPlasmac there are things done internally. The THC and Material setting are handled by the GUI. The main difference is the Ohmic sensing command that is in the G-code that is unique to the Mesa card and QTPlasmac. With Mach and UCCNC they used G31 for the Ohmic sensing, the PP I use it is G38.
