UPDATE: A1 mini blob of death
Recap: A friend recently asked if I could help rescue her sons a1 mini.
During an overnight print it developed a bad case of death blob.
UPDATE: On first inspection it didn't look too terrible. But after entering maintenance mode I realized the hot end would not heat up. I assumed a wire had gotten broken. My suspicions were confirmed in the warnings, where it said no cooling fan detected.
Not being able to heat up the hot end and pull off the blob created a challenge....
I first started by putting a hair dryer on it for a few hours to get it malleable. That had some limited success, but allowed me to remove the parts cooling fan and shroud which was firmly encased.
I knew to get anywhere I needed to get the nozzle free so I could access the screws that held the hot end in.
The hot end cooling fan was already toast as you can see in the pictures. Not only had it intruded into the fan but the expansion had crushed it. So out that came with a little snapping.
You can see that yes, the wires for the hot end were indeed ripped loose. Which I assume is what stopped the blob from being even bigger. Almost a saving grace in a way.
I was stuck, so I took a Dremel and carefully cut away as much of the blob as I could. Doing this led to huge gains, as I was able to expose the nozzle.
Using a micro torch I have I was able to heat the whole hot end and slowly get the nozzle clamp open. After that it was smooth sailing.
Now a few parts later, and she should be chooching real nice.
