V-Carve and Aspire are both made by Vectric so I assume the folder is the same. It have GRBL (mm) and GRBL (inch) pp. I select (mm) when I create my toolpath.
If I add your pp to my folder it will not mess up the other?
Then, if you can “teach” me on how to create an appropriate toolpath and how to use UCGS is too much?
