Xtool S1 stutters when engraving in LB

I keep having issues with my xtool S1 when using Lightburn. When I engrave images the laser head will run some lines at normal speed and then slow down and stutter on others. This causes inconsistent scan lines that are visible in the engraved image.

I don’t have this problem in XCS as it runs smoothly and at a constant speed.

But I prefer Lightburn as it offers more functionality.

I attached a picture of the same image with the same settings. The one on the left was done in XCS and the one on the right done in LB.

Congrats and welcome, glad you found Lightburn and this forum.

Did you setup your laser device following this thread:

Thank you. I added it in this manner and it does make a huge difference. I no longer get the messed up scan lines. It still moves less smooth (seems to accelerate more agressively) than it does in XCS but at least my engravings turn out nicely now :slight_smile:

Perhaps I’ll experiment with reducing the acceleration speeds and see if that makes any further difference but it’s definitely a huge improvement.
