    Its the same path as the previous cut. The first one was done a bit slower. The stock dimensions are less than what was programmed, that's why it cuts a bit of air but it does look like it 'plunged' but it did path is the same cut as the first vid (just reset the zero and went again).

    I think I have another 8mm roughing mill. Will setup a toolpath that that goes around the square with constant contact and see how that works.

    But did you move the stock so it thinks in different place or possibly didn't zero Y axis exactly right because to me it looks like it's doing positional move and thinks stock edge is in different place to where actually is. The fact the tool path retract distance when moving is so close doesn't allow much room for error.!

    Nope. Just Z. I'll do another on the weekend.

    Hi All,

    Just as a way of update from the OP here are two related videos - one for Fusion 360 CAD/CAM and one for the entire cutting job, with successful adaptive clearing using 6 and 4mm 3 flute roughers @ 10 and 5mm DoC respectively:





    Hopefully the more aggressive cutting has me off of the "cruelty to cutters" watch list ;)

    Awesome, nice result there.

    Thanks Chaz,

    I need to add in some single flute cleanup passes for the scalloping the adaptive cutting leaves, but it came out nicely for what I need it for.

    Looking good but when that really usefull guy shows up tell him the noise isn't the bed moving or hard/soft spots it's the tool rubbing because the Adaptive stepover is little aggressive for that portion of the Arc where it goes from Thin to Thick or vise versa. ( you'll notice it's always in corner or tighter Arcs)
    I get the same noise with i-machining and it's why I don't go so aggresive on the stepover. Having more coolant will reduce the noise, mostly because lowers the rubbing affect, but lowering step over is best if doing it in lots of areas.

    It's an horrible noise that scares the shite out you because like feels playing russian roulet with cutter.!!!
