Much better your cuttters and machine will thank you for it as well. Bet the Finish is smoother as well.?

One other thing I noticed and not sure if you have control over this or not but will save lot of time is the fact the tool is retracting above surface every time arc ends and tool returns to start while in the pocket. No need for this it's just wasting time and wearing ballscrew away, just retract 0.5. Strange thou because I can see it does this while cleaning corners out but on the large sweep cuts it retracts Z every time.?

Hi Dean,

Yes the finish is smoother.

Regarding the Z retracts - I'm not sure why Fusion 360 does this by default for the "sweeps" above 30mm, but there is "keep down" setting you can specify a maximum length for. I'm guessing this is Fusion's way of preserving the end mill's bottom cutting edge(s)?

I'll see if there's a setting for how far it retracts, but one method I know would work, may also risk rapids into uncut stock (a setting in the job height tab). More playing to be done here.

One area Fusion does lack somewhat in is the tool library, as I don't think there is a Feeds & Speeds calculator included (may have missed it). I see on the Fusion forums/patch notes however that this area is getting an overhaul soon, so fingers crossed there.

Whilst I trust in GWizard these days (since they included parameters for customising a generic router to your machine), its a pain to have to deal with a bunch of settings in one package and then transfer those (partially) to Fusion. Its too easy to miss something (e.g. HSM tick box in GWizard)

Especially as Fusion 360 looks to have most of the variables in its tool library, but they don't auto adjust when you change them e.g. change the setpover and watch F & S change to match.

BTW - thanks for the critiques - it really helps me up the learning curve and hopefully others.
