Surface Rough Parrallel

"minion...is there any specific settings in core roughing that are key? keeping in mind that i need to maintaain that slope somewhat for better clearance?'

 

I don't have experience with this type of material and if your doing this, "For roughing I use 2" stepdown with 40% stepover at 500ipm", and having good results with long tools, I wouldn't worry about a few air balls. BTW, those are not slopes, there stairs, lol. This sounds like it would make a cool video.

 

I did do a mock up of your model and came up with some numbers using a 3' bull mill using HST core vrs a more conventional strategy, that wouldn't help much here. The HST core using full vertical retracts did the best by a wide margin, but I used climb cutting throughout the tool path and it does rapid quite a bit.
