Im aligning the mirror on my new machine. I’ve got the first one that sits next to the tube shooting an accurate beam all the way down the Y axis rail… however the second mirror is shooting a beam more like a scattered buck shot beam… any help?
Is the 2nd mirror dirty? I’d suggest having a look at that & giving it a clean off either way. Might be the cause of the scatter.
yep it had tape residue on it!
