thought I would show my first cut after everything has been setup looks like I have a bit of work to do on cut paths possibly overlapping a bit lots to play with yet on it but getting results so quite happy. I am using GRBL & Arduino UNO CNC Shield and making STL Files Sketchup and exporting them into Pycam. anyone got some tips please let me know and this bit that was used was not for this but I used it anyways. it was 2.10mm bit.
Looks like you need to lower your roughing and finishing step over. Try 45% for roughing and 5-10% for final.
oh thats just roughing no finishing on it. but will try that for sure. thanks waiting for my good bits to arrive. lol
