Sometimes they close, sometimes they’re perfect!.. I don’t get it!
Belts are nice and tight, there seems to be no play in the head, I adjusted backlash on Y to .25 which seems to generate perfect circles with no perceptible start / end point, but if I run the same file 20 times, several will be absolutely wonky… I lubricated the rails, and even checked square… everything is dead on.
Here’s a photo… you’ll see that most are dimensionally perfect, whereas I can put the cutout back in the hole and rotate it freely with no binding… but then there’s a couple that don’t close, and even one in the middle which is oddly misshapen.
This is a brand new problem, and I’ve been playing for about 8 straight hours now, and just can’t seem to make heads or tails of it.
What could cause inconsistent cuts like this?
