Meltdown - some advice please - HELP

[sammo 0]

During a print overnight a couple of parts failed to stick to the bed and I've had the problem where excess material ( PLA/ PHA ) has blobbed around the print head.  ( UM2 converted to a UM2+ )

This does happen from time to time (probably about once a year) but this time it's quite a bad case.

The PLA has wrapped itself around the base of the wires going into the head, so I think the only way I'm going to be able to remove the head is to cut the wires.

Is it a lost cause?

Do I need to order a new head/temp sensor?

I'll contact the suppliers Dream3D today for some advice, but I thought I'd ask here too in case it's something someone here has experience of.

Thanks for your time

don't cut anything (yet)!

do you have a heat gun - hairdryer - soldering iron?

You can use these to heat the excess pla from the outside. Heat the nozzle to 150 or so to get some play/movement on the inside of the blob. Be gentle around the wires, you can save them.. Slowly peel away as many as you can. Succes!

The last time this happened, I figured it would be a good time to just upgrade the UM2 to a plus anyway, but that was a £400 bill.

I'll give it a go with an old soldering iron
