UM2+ LEDs suddenly dimming and flickering

Recommended Posts

Posted · UM2+ LEDs suddenly dimming and flickering

Hello everyone

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

Hi xenon,

Have a close inspection to the "led wiring" going around the corners to the upper horizontal led strip. Make sure there is no contact toward the pulleys or shafts.

Another weak point might be where the led wiring is routed through the hole in the fwd left corner (toward the bottom located PCB).

Good luck.

Thanks,

Torgeir.
