UM3 Power Budget parameter

[Ziogianni84 3]

Hello everybody, this morning after a few weeks from my last print, I resumed operations with my UM3 again. 

Unfortunately as soon as it started to heat up the print bed, the printer rebooted itself.

 

I tried a factory reset but nothing changed... then I found a similar topic on this forum suggesting to reduce the power budget parameter in the um3.json file from 221 to 200 (available via ssh in developer mode).

 

After this change, the printer started to work again... btw the point of this topic is to better understand which are the pros and cons of this tweak.

As per my understanding my current power brick is not supplying UM3 with enough power... so 1 mln dollar question: do I need to replace it or it's good to leave the parameter set to 200?

 

Can this tweak cause any damage to the hw?

 

Thanks

 

 

[Update] After a few minutes it failed again because of another power cycle.
