[Some problems.]

Ultimaker 3 can do manual leveling which I find to be just as good and much faster than active leveling (since you only have to manual level once per month or so).  So that can solve issue 1 and 3 potentially.  Buying a new BB can solve issue 2 but BB cores aren't too hard to clean.

 

In the maintenance menu on the printer you can do hot and cold pulls for that BB core.  I recommend that.

 

What happens is that PVA when at printing temps slowly (over many minutes or even hours if you haven't used that core for weeks) caramelizes into brown and black gunk that has trouble going through the nozzle.

 

Thanks a lot !

Hello,

 

I have recovered the printer from my company and I want to repair it because it has several problems:

 

1) "Low sensor performance (ER45)" when I try to diagnose the "Bed level sensor". I checked all the connectors, all the wires, and everything seems correct but I still have this error. I tried everything I found on the internet but nothing walking (clean the bed, update firmware,...)

 

2) My second extruder seems clogged (The extruder can't push the filament when it's inside the PrintCore and no material is extruded). It's a BB 0.4.

 

3) "Nozzle offset probe failed" when i try to "active leveling". 

 

I need some help to save this printer !
