Ok, I’ve been trying to cut out some aluminum for clamps. One of the members had posted a vcarve file that I’m trying to use. I did change to a .125 inch thick material
yeah, it is a bit thin for heavy duty clamps. I know, and was as much a test of the machine’s ability to cut aluminum successfully with me setting it up.
So, the sheet is flat, has some paint on both sides, but that isn’t an issue. Got the 1/8" coated bit installed and it actually cut really well. Up to a point. .125 thickness, through holes and slot along with outer cut. Machine cut great to .080 but then isn’t stepping down and cutting through. I adjusted thickness to .135, .140. .165 and .180 and machine cuts air and doesn’t go any deeper.
Reset Z with both paper and with my probe, (yes on top of the sheet, z only) and even rechecked at least 3 times with paper after probing. z is measuring zero on top of sheet.
I’ve seen it appear to step up a couple of times when cutting air and then isn’t on top of sheet at next hole. Got me bumfuzzled. Is there an issue with vcarve files being read by CM?
I’ve had a few other issues on wood not cutting through, but I really thought I had clamp bolts bottoming out and causing issue. I’m beginning to wonder… but those were CC files, not vcarve.
Oh, belts are tight, (I rechecked again, nothing skipping) Bit is tight, it hasn’t slipped. And It isn’t hitting anything but air any more…
