Just got a 60w 700 x500 red and black laser. Everything was going good and then I think I changed some setting that now my Y axis only moves a third of its travel. On the screen it says its travelling the full 500mm. Its not binding, its not slipping. Swapped stepper drivers to see if was that. Didn't help. It also is moving slower then it was. I cant find what setting I accidently changed. Any ideas?

Welcome Jaimeson. My first thought is the timing 'sprocket' slipping on the motor shaft or if there is other parts between the motor and the belt driving the carriage which could be slipping. The set screws are often hard to find and tighten [2 per pulley] but I would start there. Gene
