ECAM 5 POST Processors

I’m just getting started with LinuxCNC and have switched over from Mach4. I’ve been using the Italian ECAM 5 software and would like to continue using it. How different is the G-code between Mach and LinuxCNC? What are the main differences?

The G-code is not very different and for the most part should work.

The biggest difference is that you should set a path blending tolerance at the start of the g-code in Linuxcnc. This will be a g-code line something like G64 P0.001 Q0.001.

Other differences will be with sub program calls and O-codes and canned cycles. But unless you are doing parametric g-code (unlikely with CAM produced code) it won't matter.

Linuxcnc's G-code is also similar to a lot of Fanuc code, and with similar exceptions as with Mach3.
