Falcon2 + Rotary Kit Pro Problem

Hi
I have the Falcon2 and Rotary Kit Pro and have been having problems with the rotary chuck.
I’m trying to engrave a 110mm glass jar with a svg that is 100x100mm

Settings
Rotary Axix: Y Axis
40mm per rotation
110mm Object Dia
345mm Cirum

Whats happening is the X axis seams right but the Y axis is why out, when you do a frame it looks like its only moving around 20mm in the Y direction

Hopefully you can see that video, it looks like the Y axis is only moving around 20mm
I just ran a test of a 20x20mm square with the same settings and it burnt right.
I have also notice that when it burns a line the all wiggle as shown below

Any idea on what’s going on here ?

What does the preview show in Lightburn? (Alt + P)

You are using the Falcon 2 profile in Lightburn and have not changed the steps/mm in the $101 GRBL config?

Preview is shows as normal, I have not changed any steps settings,
I done a few flute wine glasses a weeks ago without any problems but the logo I was engraving was only around 40-50mm square, Something is going wrong once I go bigger with the logos

Can you try a different more simple but bigger graphic? Like don’t waste a good glass for it, maybe just try on a cardboard roll or so to check.
Your settings chuck / Y-axis, 40mm/rotation, enabled rotary, entering 110mm for the diameter (assuming you measured that) are all correct.

Just ran some more test on card board tube and this is the results

Just simple squares from 10mm to 60mm

This is the burn

no vertical lines, I also noticed this

Second test with the letter D size 25
one with fill and the other with line

The ringing on the lines in the first pic could mean that the belts are not tensioned properly, likely too loose.

Also it seems like you machine moves faster in the vertical direction or with way lower power than in the horizontal one. Did you change something in the GRBL settings with $x=… on the console?
