Pointing light on Laser DL445 not working anymore

I agree, it sounds like it is the length sensor in the laser. I had found it's touchy in the past - but have generally kept it in the 'activated' position and adjusted the height manually.

If that is the case (if you can get the pointer to flicker at least, while adjusting that switch), then you'd probably want to directly communicate with your stepcraft vendor. (There don't seem to be that many stepcraft staff on this forum...)

The same problem. Stopped work almost at once. Didn't write about it because I have a much more unpleasant problem.

Ok, I believed first I had same problem but then I realized it is still working in some conditions.

First condition which need to be met: The height sensor need to be in the middle position, like it is when he just triggers the height.
Second, and here I don't have an exact anser now: It works after /before I run a normal laser job but it stops working when I probe z-height with macro on UCCNC.
I will look into it when I need to lase a job and adapt the macro with the necessary steps.
At the moment I use an empty job to switch it on again after setting z-0-height.
