Engraving issues & funny cut on curves
Posted: Tue Aug 18, 2020 11:15 am
Hey everyone...just got the new and fancy setup built from LO. This is an existing AWC608 computer on a new PR650 stage with a fresh SPT 45W tube.
But I'm having a few issues I didn't have on previous laser builds. I suspect something is wonky with my X-Axis since the engraving is really out of whack, but also when I cut anything with a circle it's also a bit weird and misshapen.
Things I've done:
Upped/changed current to the motors.
Ruled out the step setting (uM) is the issue since I can drastically move it around and the issue stays.
Calibrated to within much less than a mm.
Loosened belts to make sure they weren't too tight.
Alignment is pretty centered within the 5mm nozzle hole.
It seems to cut anything square, exactly to size.
If I cut rounds, then it won't finish where it starts.
Engraving-
X-Swing Unidirectional, it's a flawless engrave
X-Swing Bidirectional, it's horrible (regardless of speed)
Y-Swing Bidirectional, it's not quite flawless but quite nice
Y-Swing Unidirectional, untested.
I've attached photos of the settings of my machine, of the X & Y axis and the image of the engraving/cutting issues.
I'm stumped
