Random Lines engraved where they shouldn’t

Hi, struggling to understand why the laser will engrave random lines when it is moving between objects as if the laser isn’t shutting off when it is moving to the next segment. it isn’t consistent though. I’ll run an job and get these random lines but then run the same image again without changing anything and there are no random lines at all. No rhyme or reason to it. Anyone know what this is about. For reference I have a 50w Chinese laser and am running it at 20power, 250 speed, using svgs on fill. Attaching pic for help. Also attaching my controller which is recognized by lightburn as ruida controller but apparently there’s some dispute about whether it’sa true ruida. !
