Rotary roller accelerate to fast

[gallie (Johan)]

Hi guys.

I need some assistance please. I was engraving this tumbler as a test for my wife. everything went smooth until the outside line was engraving. my tumbler is still slipping.
I did fill it with rice to weigh it a bit down.
I know the chuck-roller would have solved my issue, but I have the rotary-roller know, and I must try to master it.

The conclusion that I have come to with the stuff I read online is to slaow down the acceleration speed.

Can anyone help me how or post a link to a video of how to do it in Lightburn.
My machine is the Creality Falcon 2 40w, with the Rotary-roller.

Here is a list of recommendations for rotary settings:

First, only scan along the object, never use line mode. You can also reduce the acceleration for the y-axis, but if you stick to the “only x-axis moves” rule, this is usually not required.
