I've run into a major hole in my design. I mean a big hole where there shouldn't be any.
Loading the G-code on my laptop system (Smooth Stepper USB, G540 controller) I can see a giant spiral at 0,0 where there shouldn't be any.
Loading the same file on my desktop system show everything correctly. I know from experience that if I run the code on my laptop it will crash the bit into the work piece with a wide gash.
The G-code file was created using MeshCam 5 (build 37)
Any ideas as to what would cause this?
TIA,
Ken
