Rotary issues with xTool D1 & RA2 Pro

i have a new RA2 pro rotary (so no experience yet) and when making a line on an object, the rotary stops at the end of the line for a few seconds and the laser stays on, so it makes a hole in the material (this does not happen with shapes).
But with shapes it does not make smooth lines but something like a perforation (i have perforation turned off in Lightburn). When it does that, you can clearly hear the rotary skipping, but when it moves to another position, draws a line or with the test turn it runs smoothly. Without the rotary everything works as it should.
Does anybody know what the issue could be?

i contacted XTOOL support and they advised me to update the firmware. everything works fine now.
