Magnetic closing system UM5 printhead to weak for BB08?

Recommended Posts

Posted (edited) · Magnetic closing system UM5 printhead to weak for BB08?

Today i almost had a nasty experience, after i changed my nozzles to AA08 and BB08. When the print started the printhead fell open, and lucky for me i checked during the printbed heatup cyclus, otherwise it would be a certain crash!!

I experimented with all my print cores (i have 8 pieces, but only 1 BB08), and it seems that only the BB08 makes this happen. When lowering the nozzle, It pushes against the silicone piece (which i also changed) Core seems to be ok, can't see anything wrong with it.

At the moment i take no chance, and put a elastic around the printhead, to prevent it from opening during printing, and creating a major problem. Not an elegant solution, but i already saw someone else do this.

Anybody any tips?

Seems to be the safe solution at this moment? Hello Ultimaker?

are you sure you mounted the silicon pad correctly?  maybe share a photo or even better video?

Can you simulate by manually moving the BB core up and down (manually with the side lever) and will the head then pop open?

100% sure i mounted the new (and remounted the old on, which was'nt end of life)

And yes, it popped open when i manualy lowered BB down.

I just loaded the Thingiverse one in Fusion260 and cut 1mm out, so it is basically the same thing, just shorter 🙂
