Thanks alot GR.
I have some colleagues with the same printer. I will try their brick and check if it works.
If problem is solved, will post it.
Friendly regards

Hi Community,
i Have a Problem. When the printer UM2+ starts heating up the printbed OR printhead it shuts down and restarts.
Next thing i tried
raise temp for only the bed manually in the advanced menu it shuts down.
raise temp for only the nozzle manally in advanced menu it shuts down also.
Also when it shuts down i hear a click.
but the problem persists, why is it!
Hi @berkov,
Welcome in here.
(Hmm. There never was a feedback on this tread, feedback is important for issues like this for sure..)
This relay only supply power to all the stepper motors and heaters plus some indicator diodes.
So if you hear a click then your printer shout down (after a little use of the heaters), this is definitely a "power supply problem" - as all power is lost!
If you have a wire is close to fail, this might happen as in such case the voltage will drop much and printer will shut down.
Try to change the power supply, that's be the first thing we'll try with such a fault.
Good luck.
Thanks
Torgeir

That circled relay is K1. That died on my printer (it was intermittent - I actually have a video about it demonstrating the problem - I could wack it and it would work again). But I'm 90% sure that's unrelated. You hear it click because the meanwell brick is turning off for a few milliseconds.
I have about 6 of these meanwells. Some are GST like yours and some are just GS. The GST ones aren't as reliable. Anyway you should get a new one. They will turn off for just a few milliseconds but long enough to crash the arduino (and make K1 make that click sound).
If the problem was only K1 you would lose some steps (if you were printing) but that does not affect the screen or the arduino - they have power in either position of K1. Don't worry about K1. It's the power brick.
You can buy these on the internet or if it's still under warranty get one from your reseller for free.
