I have had what I can best describe as chatter on some of my cuts in 1/8" cherry. I say chatter because that’s what we used to call it when I worked in a production wood shop. Cut looks good from surface but almost looks like a chatterring router bit cut. Ideas?
Does it only happen when moving across both the x and y axes? That is, are cuts along only the x- or only the y- axis chatter free?
I will check that. It may even just be a grain issue in the solid cherry. I will check that out. Thank you!
Here is image
Looks like axis and kind of looks like the belt spacing. Maybe loose?
I can’t really tell what we’re looking at from that angle… perhaps we could from a top view.
Is that a cut along a single axis with no movement in the other axis?
Is it like stair stepping, with all of the wider parts sort of angled? Or are the wider parts parallel to the intended cut line with “indents” on both sides of them? If the latter, it could be a bent and loose wheel shaft on that axis.
Seems to be on y axis, x fine. This is cutting at little bit of an angle, maybe 10 degrees so both y and x would be involved. I may try adjusting the ecentric nut on the wheels. Did the machine tilt test but that looks fine and the belts are all centered in the coggs. Not really stair stepping. It was cut with 2 passes .
Could be grain. Could be (but unlikely) an effect of high speed and laser modulation.
It would be interesting, and possibly informative, to look at what the other side of the cut looks like. That is, what’s the cut look like on the material you cut the piece out of? If it’s a mirror image of what you’re seeing it may point in one direction. If it’s a negative version of what you see in the cut piece (each side of the cut “fits” together) then it points to something mechanical.
