  1. Hello gr5, thanks for the suggestions, I like all of them. -I just ordered a 3Dsolex block, though I had enough leaky nozzles before the UM2 that I understand the design logic behind making the nozzle and block as one part. Definitely worth trying though. I need something if I want to keep playing with that colorFabb carbon filament... -I don't need a freeby thermocouple. I'm much happier with an open-source manufacturer who sells spare parts at a reasonable profit and keeps supporting its older models, rather than one that first sends out replacement parts for free, but then removes spare parts for the Cupcakes from their store... best -Lieven Thx -Lieven
  2. +1 for this problem. I have been printing with abrasive filament, ordered a spare nozzle before and now tried to replace it as print quality has fallen off significantly -disassembly went smooth -heater comes out easily -temperature sensor stuck , looked online for instructions, tried heating the block by turning the machine on and using 'Heat nozzle' (after reinserting the heater) -tried wiggling the wire -temperature sensor eventually came out without its metal housing, which remained in the nozzle. Sensor destroyed and nozzle unusable Is there a better method to prevent destroying the temperature sensor each time I replace the nozzle? I love the machine, but this is definitely a downside. -Lieven Fablab Brussels
