Hopefully the answer is right in front of my face. I am cutting a wooden plate for a project – first run cut great, but was a little off from my measuring so I thought I would start over and try again. From the first cuts I could tell something was wrong and about 10 seconds in it snapped my endmill. I keep looking back and forth at each CC file and don’t see any differences that would make this happen. Here’s what I see:
V1 (successful cut) is set as “hard wood” vs “MDF” for V2. Shouldn’t matter as I have manually set the feeds and speeds via the forum spreadsheet. I did reduce the depth of cut per pass on V2, as well as overall to account for measurement on the material. RPMs show different (due to material selection) but that is adjusted by dial on the 611 so I don’t think that matters(?) I am trying to cut from the same piece of plywood as the first run.
DOC: 6.25mm/4.75mm
RPM: 3 on the dial
Feed: 2500
Plunge: 1250The only other thing that is different is I now have a dust shoe, but it isn’t binding on the collet, and it was adjusted to make sure the brushes wouldn’t hit the material and cause a skip. I’m hoping there’s an obvious answer sitting right in front of my face…
