[Ultimaker 3 - possible burnt damaged contact ?]

Hi there, Would you say this PCB is damaged and has possibly affected print head function quality, im not entirely sure on what the contact is for ? any info would be great , cheers!

There seems to be a number of threads now talking about print bed temperature for the UM3 and 3X.  I wonder if the worldwide fleet is aging together and hitting the same issues in batches.  We're seeing a lot of worn and broken capacitive sensor wire questions for example.

 

Would there be any interest in trying to consolidate the print bread temp stuff together on a topic?  Maybe with a guide to diagnosing issues and possible fixes?

The second problem is probably related to your core - the teflon inside is probably too big of an inner diameter.  If it's at all old I'd just get a new one.  Or try your other AA core.  Core's are considered expendable and when you think about it you spend MUCH less money on cores than on filament.

 

Do you have an IR temperature gun?  How do you know it's too hot?  This is pretty rare for the print bed - if anything it tends to be the other way around - increase resistance makes the temp sensor read too hot even though it isn't and the bed ends up being too cold.

Hi , the printcores have just very recently been replaced , is there anything else which could affect this ? cheers.

 

[Ultimaker 3 - bed temperature and filament issues.]

Hi there , my ultimaker 3 is having some issues. 

 

1. the bed temperature seems to be getting way too hot.

2. filament seems to be heating up near the nozzle inside the print core creating some deformation in the filament ( making it wider ) following this if i want to change material the filament can't be dragged back up through the extruder tube due to its deformation. 

 

Any info or help would be greatly appreciated , cheers.
