I just tried it again, but there in not even a flicker from the red fault LED.

For posterity, here is the video of my issue...

SolidWorks for makers, post processor for LinuxCNC?

Category: Post Processors

I know I am a bit late to the party, but there's a NC Shop Floor Programmer postprocessor for LinuxCNC on the SFP wiki.

Also, SFP includes ICAM Foundation for developing your own postprocessors.

Hope this helps someone in the future

Took me while to recognize that you had re-railed the thread again...
As for the control boxes: I have no idea, but I have little idea anyways. So as it stands, I expect to have answer like "well we had that one guy who nḿade it work with LinuxCNC, so that is why we claim it is compatible".
So as I am willing to go quite some way to spare me the pain of running a Windows computer with closed source running my CNC, I tend to get the mechanical parts form one supplier and gather information on which steppers, mesa cards and stuff I should get to have a working LinuxCNC in the end.
I am aware that will most likely end in a bigger amount of pain in the first run, but I am willing to risk that for the better end result.
I just wait for the answer of the cnc-stepper guys and continue from there.
