Hi Dean

Yeah it was too slow - I think I said so at the end of the first toolpath.

My current workflow with adaptive is to spin up the feeds and speeds in GWizard and then transfer these to Fusion 360. I think what I forgot to do there was tick the HSM check box in GWizard, so it was slower than it should have been. I'll tweak it for the next body (I'm making two guitars, so have a second to do) and use a bit of blown air as my vacuum is a bit asthmatic currently (need a decent shop vac).

FYI - You can manually set a value for "optimal stepover", which is where Fusion tries to get to for the majority of each cutting pass, but ramps sideways into that stepover as part of the "curve". The "optimal" stepover unless you override it is set at 40% of the cutter diameter as a default value e.g. 3.2mm for an 8mm end mill.

Its maybe not as refined as i-Machining, as how aggressive is largely governed by what you get out of GWizard (or equivalent) and I haven't found a way of getting Fusion to optimise stepover or feeds based on a slider like i-machining has (wish it could though).
