I tested some of the gcode from my bucketmill project today. Else than a bug in the tracing mode algorithm, it seems to work as intended. I do need to optimize the cutting by having it mark the places it would cut when using bits over 3mm though. Even with 3mm bits, it tends to go over spots it already cut and waste some time. Yep. I need to fix that at least for the rough modes. Final cut modes should probably be a little redundant to make things smooth.
