Hi all, I just assembled my new xTool D1 Pro 20W out of the box and i noticed that for some reason, i can move the laser module manually back and forth on the y-axis, but the laser module is locked on the x-axis. All of the belts seem tight enough, there is absolutely no wiggle in it. It's like it's mechanically locked in place! I don't want to do the wrong thing and break something with force.

Does anyone have any idea what could be happening? Maybe I've assembled a part incorrectly?

Thanks in advance
