US5 stop for no raison

[Julius 1]

Hi all,

 

 Since the begining of this week, i did a fewer print then usual with my US5. Here is the problem, (see picture)

 

It happen three times this week. On first time, I changed nozzels, clean the new ones, calibrated the build plate and did a software reset.

 

On second time, I clean again the nozzels, change material, clean the feeder. Recalibrate the built plate.

 

Now I'm at the third time.... What do I do wrong ?

Was this a one-at-a-time print with multiple objects?

Supplying a project file would be very helpful. Otherwise, we are throwing guesses out there.
