In my workshop I have a box called "Dead Bit Graveyard". Most of my bits break in the first two seconds of the carve when they hit a clamp. The solution? Easy! Increase the safety height to greater than the height of the bit.
This works and prevents the bit breaking, but it makes the carve so slow. It is very frustrating seeing the DW611 go up and down by 25mm each time it moves the bit.
How about having one setting for a start/end safety height, so for the first and last passes to and from the home position and another safety height for during the actual carve. The first one could be 25mm and the other one 2 or 3 mm. No broken bits and faster carve times.
