Re: Mach4 Comp new mode

 

How do you offset left or right with G40.1 or G40.2? Both appear to offset to the right.
Also, when using either one of these, the Status bar shows G40, not G40.1 or G40.2.
The toolpath display shows two toolpaths, one on the opposite side.
And running in Sim mode, if you use 250% FRO, I see a LOT of rounding on some corners, but none on others.
Try this code:

Hello buys,
I have added a new comp mode that is doing the set over like a Fanuc.
Before I used the method that Yaskawa used (put an arc around the end of
moves that needed to be joined) . There is a problem with this method
and that is that it will make a gouge on some very small moves. The
Fanuc method will prevent this but at the same time I don't think it is
as smooth or as fast cutting. So what I have done is added 2 comp modes
and you can pick how you would like the moves to link. The Gcodes are
G40.1 and G40.2 I sort of picked them out of thin air for testing at
this time. My hope is to get this out for testing next week and later
have it out for the rest of you to test. to say that this is complex is
a bit of an understatement. It took me weeks just looking at the problem
to find an elegant solution but I really am pleased with how I was able
to get it working in the end. This should clear up the small errors a
few of you had and at the same time give you some options if you are
seeing issues.

Thanks
Brian
