List of components to completely rebuild MK3S+ extruder from scratch

Hi!

Left printer as usually unattended and when returned found large clog on the extruder [and scary error messages]. I think the extruder soaked into it about 70g of PLA. Any my attempts to clear it appeared to be useless, so just want to rebuild the extruder from scratch.

Can anyone supply me with links to shop or just general list of parts please? I did found assembly manuals (e.g. this), but did not noticed part list in there and I am afraid I can miss some important plastic thing.

Below is the photo after couple of attempts to clean stuff. Uhh.. messy.

Thanks folks!

Start by searching for ‘blob of doom’ to see what others suggest for getting your hotend cleaned up a bit better. Once you can see what’s underneath the plastic blob you’ll know what needs to be replaced. You likely won’t need every part of the extruder assembly.

Cheers

Thank you for sharing this. The extruder was annoyingly leaking a bit of plastic before (printing at 260+C) and survived couple of 3D printer upgrades. I still think it is time to rebuild it from scratch, so to be as brand new.

Yours does not look that bad at all compared to many.

For some 'better' examples, look here: https://www.flickr.com/groups/14741465@N23/

Looking at your photo, my guess is that if you heat it up to printing temperature and let it sit, the blob will either fall off or can be easily pulled off.
