I am running into a problem with breaking bits. I am trying to do a carve with a 1 mm bit in poplar. I get about 10 minutes into the cut and the bit breaks. I think that it is the feed and plunge rate. I am trying to go 1/16 deep what would you set as the feed and plunge rate? Here are my settings.

Feedrate seems slow. What’s the router RPM? Your bits are probably over-heating and getting dull then breaking.
