First time I've ever encountered this...
Wanted to cut a piece of wood .4" thick in three passes with a .25" cutter so I adjusted the stepdown within the tool dialogue box to .15".
The Shopbot refuses to accept the changes and instead cuts the full depth in a single pass???
I thought I had screwed up so I tried it a few more times with different cutters within Parts Wizard, same results.
Why do these things always go wrong on the last job of the day?
