I am carving 3/4 inch PVC and am getting small islands left in some areas - or perhaps I should say deeper cuts in some areas of the path that are maybe 1/64th of an inch or less. (please see photo) What could be causing this? It happens quite often.
I should say that this pocket area was all cleared with a 1/8 o-flute bit. But this has happened with my 1/4 inch bit as well.
Check the tip of the V-bit for damage or unsupported geometry (radius or flat). These can lead to the V-bit carving too deeply because they Bit setter is measuring the actual tip not the “perfect” point.
Thanks mhotchin. That is something I should really check out. I’ve had my Shapeoko Pro for over a year and have been using it pretty heavily. Even if thats not the issue - it would be a good best practices. Thanks!
