Hi,
I have just finished putting together the ortur LM3 10W. And when I turn it on there is a yellow light with two bips. sometimes, the laser trolley moves to the bottom left of the frame and keeps moving with a clack/clak/clak nose form the belts.
When I press shortly on the button to turn it on there is yellow and blue blinking alternatively…
In short it doesn’t work. Anyone got an idea of what that can be?
