Hi everyone - I’m a newbie to the engraving world and got everything up & running with my Creality Falcon 22W laser + Rotary Pro. I’ve watched all the YouTube videos for full wrap tumblers, messed with all the settings and after trying different things for hours and scouring the internet for my specific issue… I’m still at a loss.

The laser is engraving tons of lines (I’ve adjusted power settings, I’ve focused the laser properly, I’ve adjusted speed, etc) and it’s not even engraving the entire project (it’s done in 20 seconds) and I don’t even know what I’m looking at…. Please help

I’ve attached the photo of what I’ve been trying to engrave just to practice & see what happens since the full wrap wasn’t originally working either and resulted in the same outcome (also attached)

Note that I’ve followed all the measurements for the “working space” of the size of tumbler in order to do a full wrap. Framing does just fine. When I preview it shows everything going as it should but as soon as I “start” it’s just all over the place. I do also connect via USB to the laser, not TF card, if that makes a difference.

It seems that the files I try to engrave are being “stretched” as I can see part of the guitar on one side of the tumbler but it’s huge, I tried another file and shrunk it down and it still engraved large… any tips?

      Show us what your PREVIEW looks like… and be sure to ENABLE ROTARY
#2 - start small with one thing at a time
#3 - prove the graphic on the flat before you move to the rotary. Cardboard from Amazon or USPS priority boxes makes for good test matrerial.

      First thing I see is you’re running in line mode rather than fill. Definitely not recommended to run in line mode on a roller rotary and less than ideal on a chuck. There is too much back and forth movement that leads to slippage. You don’t say whether this is a roller or chuck rotary.
Second, I would guess that your rotary setup is wrong. You need to get the rotary set up properly before you can expect good results.
Tell us what rotary you’re using. Show the Rotary setup screen.
Before ruining another tumbler to testing, wrap this one in painters tape and perform your tests at low power to only mark the tape. You can rewrap multiple times until you get things set up.

        First of all make sure your rotary is hooked up to the y axis I do not use the rotary setting on mine also do not use svg files its too much moving for the rotary to stay aligned try using jpeg or similar file and make sure your x axis is moving back and forth and the rotary is not try doing the images seperate as well.
