    Do you have tips for milling bigger pockets in a shorter time?

    That on the picture took me 6 or 7 hours.

    holes (depth 15mm)

    • 8mm, double flute
    • 30mm/s feed
    • 45% step over
    • 2mm depth of cut
    • 24000 rpm (max)

    pocket (depth 15mm)

    • 8mm, double flute
    • 8mm/s feed
    • 45% step over
    • 5mm depth of cut
    • 24000 rpm (max)




    With a single flute you should be able to go deeper per pass and a little faster. The only other thing is a larger diameter bit.

    Is that plywood? Not that it matters I guess….my thought or question would be could you cut holes in thinner stock and laminate it to get the pocket and thickness you need instead? Wood glue is pretty amazing.

    You could also use the precision of the MPCNC to just mark the centers for you and the pop a forstner bit in a drill press with a depth limit set.
