Power fails

Recommended Posts

I am not sure if I understood what you wrote, but you mean, that you are wondering why the UM3 is not resuming the print after a power loss?


If so, yes the UM3 is imho not able to resume a print after power loss and it has nothing to do if you print via USB or via network.

It's possible to resume a failed print but it requires manually editing the gcode file.  And if it's a dual color or a dual filament print it gets quite complicated.  I have examples of how to do this somewhere on this forum.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
