Hi all,
so finally got around trying the new door design, and it was a full success! The model that failed after less than 20 mins before, now went through in 7 hours. The filament does not show any hint of broadening/heat creep, neither on left nor on right nozzle. Already informed support about the success, now waiting patiently for what they make from it - my assumption is that they’ll release a new front door and send this to those affected. I am curious how many this might be - would you mind answering this poll:
Side remark: Since the new firmware now issues a warning if your standard retraction exceeds 2mm, I lowered it to 2mm. I will not leave it there - my black filament oozed like hell! I personally believe that retraction settings that do not make molten filament get into the cold zone will be of no problem - from looking at the size of the heater block I’d assume that anything up to 10 mm would be safe… but that’s currently just an opinion, will establish this over time by testing.
Oh, and btw., Support said as soon as I verified that the door is good, I can share it - find it here:

A big THANKS to Snapmaker support for taking care and providing this file!
