Just have a wierd one where my laser isnt firing. I have a “red black” ruida 6442 Chinese cutter.
I’ve Doing some testing and if head is all the way to right it works, approx a 50mm range. Move a bit left it goes off. There is an audible click when moved and a light on psu goes off. Any thoughts? The Y axis is perfectly fine. I Only have homing limit switches and I have tried disconnecting them but it makes not difference.
Video of the problem.
