We've recently installed a brand new Biesse rover S FT 1536  and running a test at the moment. 

We found that the compression cutter that we are using is leave an unclean edge on (1) or (2) sides of the part along with a lip that is aprox. 1m h x 1m deep that we are trying to get rid of.

Currently we are using a two step route and tried different speeds on the CNC with the same results.
Any insight would be so greatly appreciated
