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

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

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?
