so hitting the arrows on the controller, it just shutters.
i was finishing up a project in lightburn, it cut
everything, then started to engrave (numbers, for each piece)
then, finishing up one of the last numbers, it began
now, it just shutters, jiggles, vibrates, and all i hear is a whine thats driving me crazy. i already reset the parameters, checked everything,cleaned everything., what do i do???
