Job countdown continues to run down and fan stays on yet laser head stops moving

Print head just stops moving at random point, but job countdown continues and fan also stays.
I can’t specify what is the problem…It happens very on and off… Sometimes works well with same design… so I don’t think it is design problem.
Please help…

If you are getting an overheating notice and it can cool down and then keep going. the time keeps going but the job will finish. If the head feels hot when you touch it after that might be a different problem. I would make sure the mirror at the top is clean as a bit of stuff on it would heat the head up a lot.

Beyond that the sensor passes though the white ribbon so that connection may need looking at. when you get all the info and photos before you contact support that ill move things faster.
