UM3Ext Print starting -> print aborted (logs inside)

Recommended Posts

Hello,

 

We have a rather new UM3Extended which i have been using for about a month now. After changing filament today, im not able to start print jobs.

The printer will run the pre print operations as it usually does (heating, levelling), but as it raises the bed to start the print job it will immediatly go to "Print finished".

 

I got the logs and it seems to fail at "Exception in file handling"...

I have tried with two different USB sticks (the one i usually use, as well as the one that came with the printer).

 

Snip from the log:

    • "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.
