I am using a Longer ray 5 20 watt with a Longer rotary attachment. I set up the Y-axis step to 56 from 80, set the axis rotation with tape and marks. set the roll diameter. set the cup diameter. and I still get the lines not lining up.
When I run the same project on a flat surface everything is good. I tried changing the settings but nothing seems to affect it in a good. Is there a compatibility conflict or could there be? or is there some super secret squirrel setting I missed?
Can you send us screenshots of your rotary and cut settings, and pictures of the outcome? That would help us help you.
This docs page is a good place to start:
The tumbler might have slipped on the rollers, this is a common problem
In the same spot 17 different times. Not sarcastic the reason those cups are different colors is because i would try, paint the cup and try again. I ruined 7 cups trying this and then decided to try and paint them.
You don’t say or show your workspace. Is this line mode or fill mode? I don’t recommend using line mode on a roller. Slippage is an issue.
Also, please use actual screenshots of your screen, not a phone pic, easier to zoom in and make out small text with a screenshot.
For me, it also looks as if the tumbler has slipped while turning.
It probably helps with the grip if you spread the rollers further appart:
You should not need to change the “Machine Settings” Y Steps per MM ($101 firmware setting).
The roller’s motion gets adjusted with the “MM Per Rotation” value in the Rotary Setup.
I suggest reverting $101 to the default. If I’m not mistaken, It should be the same as $100=80 for the X axis, but double check this by engraving a flat rectangle at a known size and measure the outcome.
You can change this value in Machine Settings, or by entering this command in the console:
$101=80
Then adjust the “mm per rotation” in the Rotary Setup. According to this Longer doc page, 56.52 is the sweet spot.
Clicking the Test button should rotate both rollers one revolution and back.
