I have to give this item a 1 star rating. Why ? Well it’s because no information about the specification is provided, which would allow a new one to be checked against old one prior to replacement.My old thermistor measures 101kohms at 25 C and a new one around 90 kohms. But I have another one measuring 7 Mohms. Both the latter purchased at the same time from Prusa. The high resistance item is clearly faulty, and my old thermistor seems 10% higher resistance at room temperature so might be out of spec. But how can I tell ?

Fantastic product! I prefer to buy my parts from Prusa, but if they are out (reserved for new printers), you can find the Prusa supplied parts (hot ends, etc.) at: (UK). In the states, try .

Sound like you are using the wrong nozzle... should not leak. Get some good tools to do the nozzle change, and get the right nozzle (E3)
