HELP. Please. Somebody. I’m about to see just how far I can throw these tumblers… and this rotary setup to go with it. LOL

Been working on figuring our the rotary and tumbler settings all week and am beyond frustrated.
On top of working to figure out my correct speeds, feeds, pwr, interval etc, I have lines on every test burn. Whether it be a logo image I’m trying to make or small test squares. Same repeating lines.
So far I’ve cleaned the laser, checked the focus, changed the lines per inch (tests with 300, 350, 400 & 450), tried adjusting the rotary mm per rotation, changed logos to text to generic squares.
Getting closer on my speed/pwr/interval via my test squares but can’t get these lines gone for the life of me.
Any help/suggestions would be greatly appreciated.
Lines are gone but now I probably need to slow it down. The OneFinity now jerks back and forth a lot more and the tumbler is moving. Progress but more to figure out. Thank you!
I have a chuck, so the tumblers do not get to wobble funky. I run about 30-50% power on a 5w diode and from 2400-3600 mm/m. I keep my interval for the rotary the same as I do for the flat frame. -->.1mm ~254 lines per inch.
The setting that I do make changes for is the overscan. Default is around 2%, for rotary I go as high as 8-10% for the heavy stuff. Regular Yeti mugs 5-8%.
Looks like it might’ve been 1 step forward, 2 steps back. When I burn on the 90 degree, the tumbler doesn’t stay in line, it “sways” back and forth with the rotary turn. Wondering if this is a problem with the rotary unit more than software settings?
Any other suggestions to get rid of the vertical lines without changing the 90 degree angle burn? I’ll also reach out to JTech. They have been very responsive on a question when I first got my laser. Hoping the same again.
Just heard back from JTech. Said it should run on the x axis and slow the speed down. Didn’t address any issue or question. Pretty disappointing. Still on the hunt for answers.
I hope you can find your answers! Sometimes I try too hard. This wood block is the same image, with my original file that I wanted to put on the tumblr. It was a bit too far of a stretch for me. Maybe with the mopa laser or a plain stainless tumbler?
Quick update - Nate at JTech (who was out on my previous attempts to engage JTech) immediately got back to me when he returned from vacation.
Great communication with some back and forth emails and ended up jumping on an hour long phone call to figure this out.
JTech has some new settings which we corrected and were able to get the rotary and laser working great. Ultimately between updated rotary setup settings and going with 50in/min with 20 power, 0 angle and we are golde
