SOLVED UM2+ keeps rebooting/power-failing

[schamar 2]

After 3.5 yrs of extremely reliable operation, my UM2+ recently started to quit printing due to a power fail and reboots. This happens when

- printing from SD as well as USB

- pre-heated as well as cold

- using different models

- using different slicers (Simplify3D & Slic3r/PrusaSlicer)

- using different filament

 

It happens either directly after heating bed and nozzle, or a few minutes into the print. (I have a video of the failure if that helps, but didn't attach it here)

 

Can anyone help me? Thanks in advance

This is pretty common.  The power bricks are running close to their limit and can age.  I'd get a new one.  There are software solutions as well.  MUCH more info here:

Ok, thank you. I've just ordered a new power brick and will let you know whether the issue is still there.

Addendum & close: the new power brick has arrived and works perfectly.
