Al;

Like your theory, makes sense but when only thinking about diameters etc. My questions are:
1. Do you have the problem? my machine is an older one but my hours are less than most of that age. I last ran my carver in February, just had to prioritise my time and it lost.
2. Why does the carver load both the bits without any problem initially. Both the 1/16 and the 1/8 load, spin and touch down without any 'damage' to the area.
3. Am running the 'base' generic 1.187, has anybody had the problem with the newer versions?
Don't have a clue as to the answer, just throwing out what if's that come to mind.

Thx, Rcik H
