OptiRough Cutting Air

[MSlanker]

I'm trying to just rough out the angled slot on this part but optirough is acting like there's stock above it. The perimeter of this part is going to be done when I run this toolpath, I have my stock model made to reflect that. Only way I got it to just cut the slot was by turning rest machining on but since that locks it to stay inside it wouldn't cut the bottom of the slot leaving a chunk of stock. Any advice on how to get this working is appreciated. Unfortunately I'm unable to share the file.

Under Cut Parameters - Steep / Shallow

Set your Z min depth to -.001" - .002" below the top surface, that should take care of the top 'skim' pass

with rest machining you make the boundary bigger for tool entry.  you only need to make one side bigger

How do I make the boundary bigger?

I got it now, thanks for the advice. Still learning the ins and outs of this toolpath.

sometimes you need to draw a custom one and depending where it overlaps you can control the tool entry area so it doesnt need to helix or ramp
