  1. When swapping filament, I select change material, it heats up and reverses material with no issues. When feeding new filament, I cut filament to ensure a flat end, then push it into the feeder, wait until the end just shows and click OK on the printer. Filament moves along the bowden tube and into the print head. It's here that the filament seems to stop (if I look at the small indentations on the filament through the bowden tube, relative to the clips it seems to be stationary). No filament at all comes out of the nozzle. I've tried to heat nozzle up to 260 and use the move material option and no filament extrudes at all. I've just swapped back to the original filament - to print the larger spool holder ;-) and seems to be printing fine. Once this print completes I'll swap back and see if the problem happens again. Thanks!
  2. Hi, the quality of the prints was fine-no signs of under extrusion. Printed 4 or 5 things without any issues, it was only after changing and loading filament that no plastic at all came out of the nozzle. I had to re-adjust the feeder spring again as well as do an atomic clean. I'll try changing filament back again and see if the problem happens again. Thanks for your reply.

  4. Hi all, I've recently got an UM 2+ extended at my workplace and have a couple of issues with it, firstly on the initial print the filament did not extrude from the nozzle. I did an atomic clean just to confirm that there was no clog (which didn't seem to be the issue), I then adjusted the tension on the feeder and was then able to print ok. Great I thought. I then changed filament and same thing happened, repeated above process of cleaning nozzle and adjusting tension on feeder and managed to extrude plastic. Have people has similar issues on the UM2 +? I have been using a UM2 for around 2 years and have never had this kind of issue. Second query..whilst changing filament from the genuine UM filament that came with printer (750g) to Verbatim filament (1kg), I noticed that the spool holder seems to have reduced in size, so now will not fit the 1kg spool on. I know I can print another larger holder, but was surprised that this had changed. Anyone know why this was changed!? Thanks, Andy
