I'm having a problem with my UM2+ , i've had the machine for several years and the LEDs never gave me any problem.
However yesterday during a print the LEDs went extremly dim, i tried to go to the settings but the brightness was alredy at 100% and changing it did not have any effect on leds, except that they for no reson got a little bit brighter when set to 0% (that actually set the led to 1% instead)
i continued printing but noticed that the LEDs also flicker during print and the do when the motors make a quick acceleration.
have anybody an idea on what's going on and possibly how to fix it?
can i resume printing or there might be a bigger problem behind the LEDs dimming?
thanks in advance
