Ortur LM3 printing on angle

Hello. I just received my OLM3 last week and I am new to laser engraving. I keep running into the same issue while trying to engrave a 9x12 canvas. When framing the project, the laser shows the project completely on the canvas perfectly. When actually engraving, the engraving keeps slanting, eventually going off of the canvas. I have tried to tighten the belts to include the X-axis. I am not sure what else to do. I will include pictures and settings of the project. Thank you!

I have the same exact problem on my LM3. Same angle as yours shows. The problem just started today. I have done all the belt and pulley checks. I have tried different speeds. So far have found no fix.
