Posted (edited) · UM3 Power Budget parameter

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.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
