Flooded Print Core

[Autocam_Medical 0]

Having trouble with Side 2 on our S5. Trying to print ABS and a 0.4 Print Core clogged up and flooded the whole print core. It was a pain to get out. Tried again on the same side but with a 0.8 Print Core and got the same result. I pulled off the back of the feeder but don't see any immediate problems then again I haven't done any maintenance on the feeder before so unsure what to look for. Any ideas?

I've never seen this type of flood.  It looks to me like the core is leaking.  I'd get a new core.

 

Normally there are 2 possible causes of head floods but this is a third cause I think:

1) Door magnets aren't working well and door flops open during print (seems to be pretty rare)

2) part comes loose from bed part way through print and the part is wider than tall.  Then the part is slid around the glass bed like a hockey puck and the nozzle keeps extruding into the "puck".
