Any news or movement on this?

jcoffland commented 2 years ago

No progress on this. It's not too difficult to implement. It just takes time/money that I've not had available.

Thanks, I am struggling with trying to find another solution and going around in circles. How much would it cost if I were to pay for this to be done? Thanks

I've looked again at what this would take. I couldn't do it for less than $5k USD. And that is to implement CRC as defined by LinuxCNC.

Are you sure this will solve your problems? Cutter radius compensation is fairly restrictive. It only looks at the current and next move. If you have any moves that are shorter than the radius of the cutter it may result in gauging. If you need more complex polygon offsetting there are other ways to do this outside of GCode.

What is your input format? Can you explain more what you are attempting to do and why you need cutter radius compensation? There might be a better route.

Here is some more info on CRC from Mach: https://machmotion.com/blog/what-is-cutter-compensation/
