PLA blob of death - need to replace thermistor, heater bock, etc.
RE: PLA blob of death - need to replace thermistor, heater bock, etc.
Sorry to hear that. It happens pretty often. Usually you can scrap the heat break and heater block. Just use a heat gun or any heat source to bring it up to ~60-100C temperature. You should be able clean up everything.
So you should only need a new heater cartridge and thermistor. I prefer printed solid over matterhackers but both should do the job:

Remember that if you have the MMU that the heat break us not the same as the default one from e3d... Where you can get the prusa specific one I don't know though. Without MMU the normal heat break is fine, possibly even better then the prusa modified version.
