Tangential knife cut different size of figure when cutting by CW and CCW

Open voleoo opened this issue 1 month ago • 1 comments

I made tangential knife for cutting and now have some strange issue.

I open the SVG file in GRBL-Plotter and it generates g-code. G-code for first figure generated cutting direction by CW and cutting the second figure CCW.

The figure that was cut CCW has the wrong dimensions. Should be 230mm but actual size 234mm. Looks like we have some compensations for tools. If direction CW sizes is correct.

How to generate g-code with direction by CW.
