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.
I used eCAM 5 and I'm happy with it, now I got the new 6 for a small CNC. I don't use it much, it's not my job, but the lathe part, according to a friend who uses it on a CNC lathe that we retrofitted together, is excellent.
i have a post i modified main things i had to fix are threading g33.
everything else in the post i have checked works well i use it on a production cnc lathe running linuxcnc.
Ecam is absolutely awesome. way better than fusion 360 lathe cam in my opinion and i used both for 2 years
my post currently still has one issue left. when using g97 constant spindle speed the post still outputs a D value for max speed. and linuxcnc throws a error on this so currently i just delete that code from the file. but it's on the list to fix at some stage.
