For users of GRBL I put together a Blog Post describing the issues with F-Engrave and the settings needed to generate g-code that will work with GRBL. Below I listed the settings needed (without the long explanation from the blog post).


F-Engrave settings needed to generate g-code compatible with GRBL:

- Select the “Disable Variables” box in the F-Engrave Settings window

- un-select the “Enable Arc Fitting” box in the F-Engrave Settings window

- Use F-Engrave Version 1.34 or higher
