Gaps on cuts and engravings

im very new here. i got the xtool d1 and its been working fine for a month now til last week where i would press start and it would stay still and laser would be on. then after that it would go left to right like a 4 inch length and the project would only be 1.5 length. then now after that issue went away i am having tabs on just the shapes i sample cuts and just really frustrated and ive been on forums searching and reading and finding close situations to this and having to find out that its been deleted or hasnt been solved.
