Ultimaker 3 keeps resetting itself when i use support from 2nd head

Recommended Posts

When i start a dual head job (so with 2 cores), my printer keeps resetting itself.

First it heats its platform, then it starts heating core1, and after about 2 seconds it totaly resets itself, display and all the heaters out, and then a message on the screen that the print went wrong....

First i thought that it was software related, but it also happens when i do the X-Y offset calibration.


What steps i already did:


-Replaced the 2 cores.

-Factory reset and calibrated the Z 

-Took the printer apart to check if there was somewhere a cable or connection problem (and cleaned everything 😉

-replaced Usb stick

-print with only core 1 > ok


What else could i possibly do? 


Is there a hard reset possible? Should i bring my printer to the dealer?

    • "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.
