  1. Thanks for the reply. I really don't want to start messing around with my U2+, I have it so dialed in now it's unreal....lol. I guess I'll just have to keep the 1.75 for my Mk3 PRUSAs ?
  2. Hi Can I put 1.75mm filament through the 0.4mm nozzle on my U2+ (I've been using 2.85mm for ages!)? If so, is the only thing I need to change the settings in Cura? Many thanks for your help :)

  5. Hi I have the same problem, although mine sounds more like a squeak than yours. I've had my 2+ for about 3 weeks now with quite a bit of use. I've tried to find help on lubrication, but can't seem to find any info on it. Can some one point me in the right direction? Many thanks Would be interested to hear peoples thoughts.....
