What are your laser accels?

So I’d try adding some extra weight to the carriage?

Well my laser is attached to the side of my 2.2kW 10pounds spindle…

You can also try a better path for the laser. It looks like this one is a very raster back and forward motion but if you tried an “adaptive” path (tell Fusion you’re using a 0.01mm endmill with crazy feeds and speeds :D), there’d be less change in acceleration.

That’s an interesting idea! I’d like to see the look on LB developers faces when I submit a feature request for adaptive toolpaths

That reminds me of the time I used a regular pocketing toolpath with a diamond drag bit to fill a vector, and it turned out to produce an interesting look compared to a raster approach. It would probably look similar with a laser using a regular milling toolpath simulating a teeny tiny endmill.
