Jitters only with lightburn

Hi there, I have been using lightburn for a couple of months now and it was working fine and then all of a sudden my laser started to jitter when I try and use it.
I had it at 100 speed and 100 power like is most common for the 3d engraving I like to do.
I also use xcs for my xtool d1 pro 20w with no issues or jitters.
Any advice please?

What are the units for this. Are you using comparable units between LightBurn and XCS?

Hello, sorry for the delay in answer, the units are mm/sec and yes they are comparable to what i use in xcs

That’s odd. Can you upload a sample .lbrn file where you’re having this problem?


This is the one I was trying to do

Can you upload the actual LightBurn .lbrn project file? Want to review for any potential potential issues on the setup.

Is this happening on only one file or all operations?

Sorry for not replying sooner, my mom passed. The jittering happens with all files, I’m pretty upset because I paid money to use something that I’m not able to use

Sorry to hear and nothing to apologize for. Hope you’re adjusting well.

Are you able to upload the actual .lbrn file that you were having a problem with?
