  5. Re: Soft plastic milling help needed (video to demonstrate the problem)

    Definitely decrease the stepover and increase feed rate. Failing that, get a bigger end mill ! I cut acrylic at 2000mm/min 16,000rpm 0.5mm DOC with a 3mm single flute

    Re: Engraving Depth Regulator Attachment

    A little bit confused with their depth controlling nose cone, I looks as if the nose cone piece spins also ? I am trying to engrave engraving laminate, I think this would damage the surface somehow

  12. Re: About to purchase a PRO4894, question about accuracy

    I've been able to get stuff within 0.1mm on small parts with my PRO4896. As long as you put it together right, shouldn't have an issue ! The email support from CRP is top notch.

    Nil backlash, this thing is tight as. Reset the steps per to the calculated value and it's within 1mm of the full table now, and that could be in the tape measure. I flattened out the rivets in the...

    Re: Issues with accuracies

    Exactly the same as myself mate, so did you find doing it that way, working within smaller areas you maintained accuracy ? I'm trying to cut .5mm (0.0020" ) increments for inlays in Acrylic.
