Printer try to print above the body of what is already printed

Recommended Posts

Please help! My printer UM2 was printing along and then all of a sudden it raised above the printed portion on the bed and started trying to print in the air above what is already there? The print job is only about 1/3 complete. Why would the printer do this? Is this an issue with the file or with the printer?

Thanks in advance for any feed back !

difficult to diagnose this, were you watching it all the time ?

if the print head gets blocked the printer does not know this and will just carry on printing, so if you missed the moment when it stopped it will just look like it s printing in the air above the print.

I would recommend you check the feeder (at the back) and try a "atomic clean" (http://support.3dverkstan.se/article/10-the) of the print head

    • "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.
