Hello,
I’m brand not so new lightburn user.
I just bought a small galvo scan Raycus 20w based with à 110x110mm lens.
I have a perfectly well tuned and functionnal rotary chuck installed on Y axis .
But something burriyng me when I mount a ⌀70mm thumbler I potentially have a 219.911 mm circumference on Y axis against the limited 110 from my lens,
My question is, is there any way to override my 110 Y limit by the circumference when using a rotary ?
Thanks for your lights 
If you have a cor file for it, then I think work area is grayed out…
Mine came with the factory setup and I can change the work area size… haven’t tried it, but the numbers are not grayed out…
These are in the Device Settings… 
Let us know what you find…
Hello,
thank you for answer sometime thing are so evident … I was able to modify my machine params in chord with the circumference. And i’m now able to engrave the whole 360° surface !
Maybe Lightbrun Devs should integer an automatic dimension upgrade ?
Thanks for all !
A better explanation would be appreciated…
Others may have this problem and your answer is rather abstract, rather than one with more detail of what/how you achieved success…
Glad it’s up…
Ok you are right
So for à focal lens @ 110x110 I was limited to the machine surface even rotary activated. For a ⌀70 tumbler i have 219.911 mm circumference that is less than 110 on Y axis, so for cheat my surface limits i where in the machine params and i modify the 110mm Y axis by the tumbler cirumference. So i could profit the whole 360° tumbler surface to engrave it.
With hope i’m clear with my poor english.
Thanks
What I suggested in the first post…
When I use a cor file, these number are grayed out, so I can’t change them… wonder what to do then… ?
Great it’s working like you need…
You English is much better than my <your language> is … 
Yes and thank you for driving me to that
I guess this could be automatic in lightburn for rotary config activation. When using the Rotary you anyway are locked @360° on its own axis so the circumference could be “the” variable
Don’t follow the meaning here… the rotary is just a cylindrical Y axes…
