Bad LED ligt UM 2+

Recommended Posts

Posted · Bad LED ligt UM 2+

Hi

The LED on my UM2+ (upgraded UM2 to 2+) is only giving 1/3 of the light it had.

I have 2 LEDs on the right strip with full power all other LED is dimmed to 1/3 power

The brightness is at 100%

Any suggestions?

Can you check if the light it's brighter at 50% and at 0% doesn't go off?

The 2 LED that are brighter, are brighter all the way from 1% to 100%

The dimmer works on all light

On 0% every LED light turns off

Here it is at 1% brightness

The strip that has less light might have get some part bended and that might be the issue? Just wondering if you tried to move them because the glue seems out.

The strip that's low on led it's at the end of the chain of leds? I don't know how led strips die but worse case scenario a new strip from ultimaker was 19€ or something alike whenI bought mines a year ago (there are cheaper ones but ultimaker sells them ready to plug without need to solder or do stuff)

Hi, I have exatly this problem. LED ist just at 25 % of its brightness, it does not go off or change its brightness if you set up a value from 1-100%.

If I set 0%, it is getting brighter and not turning off ??

You know this problem ?

You can open the electronics board and switch your side fans and LED connections in the electronics board.

Then, try to control your LEDs using the fans in the menu Maintenance --> Advanced --> Set Fan Speed, and try to control the fans with the LED menu for brightness. If the LEDs are responding normally when plugged into the fan port, the problem is your electronics board, not the LEDs. If the LEDs don't respond correctly in either port, then you just need to get a new LED strip.

You should do the @fbrc8-erin test, to be sure. If isn't the Leds is the bc817-twenty something.
