First time setup, print nozzles different heights?

[HannahFink 0]

I'm setting up my printer for the first time and want to check that the differing nozzle heights is normal. I installed the BB 0.4 nozzle on the right side of the print head when prompted, but it appears to sit lower than the AA 0.4 which was already installed on the left. Is this normal? Should I have inserted the extra AA 0.4 on the right side? What is the difference between the two?

Completely normal.  On the upper right face of the print head is a lever.  Pull that towards you and it will left the right core.  Release it and it lowers the right core back down (it needs to be lowered to slide the core in and out).

 

the cores are identical heights by themselves but the right core alway sits lower when you first slide it in (and higher when the left core is printing).

 

This is because the unused core, if used in the last few seconds, tends to leak a tiny bit so it's held just high enough over the part being printed so that filament doesne't end up in the part on some random spot.

 

It's okay also to have the BB core in the left and AA in the right but no one does this so I recommend you don't do this also.  But it should work.  I would hope.
