Hello,
Thank you Torgeir, I will order the (D16) Diode and i will give you some news as soon as i change it.
Thanks,
André.
- 1 month later...
Just to give here a feedback.
After replacing the regulator and the D16 the machine is already running.
Thanks all,
André.
Way to go! 🙂
Thanks for the feedback.

Hello,
After some time running (75h +-), after a while the UM2+ restarts without reason.
Today morning i tried to heat the extruder manually in the "Advanced" menu and she restarted..
Other test made is start a print and after half an hour it restarts, but while is printing the leds seems to slightly blink.
Anyone with this problem?
Hi,
You might have an issue with the power fluctuating! It might be due to your power connector feeding system, or due to some component (located at the main PCB or external component connected to this PCB) drawing to much current intermittent. An intermittent power drop will cause the processor to restart..
Easiest -is to try another power supply.. Since this occur also cause loss of 5 VDC, -the main power for the processor.
But might also be sign of a failing component taking down the 5 V DC power converter for the second time.. There might be a sign of an overheat on another component, did you check?
Thanks

Error and more info.
Hello Torgeir,
Yes, everything seems fine, and this problem occurred to me a year ago more or less, but the printer was fine for 8 months or more, then after that it burned the D16 and the stepdown, and now it's doing the same thing as a year ago.
I'm printing now for 2h with the heatbed turned off and it seems to be fine, and for what i've checked here in the forum the Power brick may be the cause right?
Need to burn more 80+€.. damn printers.... 😞
Br,
André.
Hi André,
Good test, -printing without using the heat bed -in order to sort out of a such a problem..
Sure, the power supply always takes the heavy load, and it's the problem in (80-95)% of ~all kind of electronics failures, -cause they are very often under dimensioned!
As usual, good luck.
Best regard
Torgeir

Hi @AndreCarvalho,
When we change this kind of switch regulator, we'll also change the fly back diode (D16) as well.
When you look at your thermal picture, there is two hot spot.. And the other is this diode.
Also check that the 5VDC out line have no direct ground (other circuits might cause the power supply to fry).
Normally it's only this two active components that's fails like this.
Ok., good luck.
Thanks
Torgeir
