Unnecessary Z movement, Rapid to depth required.

[jye.hall]

Hi all, 

Just a quick question,
when using the 2D adaptive toolpath, I noticed fusion 360 generates a 2mm axial clearance from the specified bottom height when rapid traversing to position (will rapid traverse to position, 2mm above required depth, then feedrate to depth & lead in). Is there anyway I can prevent this happening and get the tool to rapid straight to depth?? (Without editing the code long hand obviously).

Thanks

Jye.

Without looking at your project my bet would be you are using plunge as the ramp type and this 2mm is your "ramp clearance height".

Try changing your ramp clearance height to 0 and see if that gets rid of it.

Thanks for the reply Richard, 

Still doing it unfortunately, Tried with both plunge & helix ramp type.

Are you able to attach your project?

Sorry for the late response, Here you go

Late edit:

I noticed if you remove the horizontal lead in/out radius it will linear feed straight to depth like i want it to, but without the rapid.
