A couple of days ago I was using my machine like I normally do, when I was on my last cut I noticed the cuts were not straight, for example, the circle I was cutting was more like an oval. I thought there might have been something wrong with my design so I tried it a couple of times and it kept doing the same thing. (this is a design I have cut more than 40 times in the past) On one of the cuts, I heard a loud sound and when I looked at the machine the laser arm was out of track. I turned off the machine and placed it back on track but every time I turned it on and it started doing its thing the laser arm kept falling off track. I cleaned the tracks, made sure the area was cleaned of any particles, and made sure the belts on both sides were tight. I have managed to keep the laser arm on track but now the right side of the track seems to move faster and the left side has a delay, I tried cutting and even engraving and everything is still off my cuts are no longer straight. I have tried aligning it, cleaning it, and tightening belts, I checked for broken wheels and nothing. I don’t know what else to do 
P.S. I have had my machine since July 2021 and have never had any issues.
