Compensate the tool radius G43

Hi, I would like to know how to use the G43 command to compensate the tool radius. I have a Shapeoko 3 machine and use the Carbide Motion program. If possible, make a code example with 10mm radius compensation. Thank you!!

Tool radius compensation is G40/G41/G42. G43 is tool length compensation.

Of these, the only command supported by Grbl is G40, which turns tool radius compensation off.

Generally speaking, Grbl avoids supporting commands that are primarily used to write or tweak G-code files by hand, like variables, loops, branching, etc. If a CAM application is generating your G-code automatically, that application is a better place for this logic. I think radius compensation falls into this category.

The G43 command is therefore to compensate for the length of the tool. How do you make a point ray compensation? Not in length but in width. It's possible?

I believe G43 is now supported in Grbl 1.1
