  1. It would be worth taking the Bowden tube off and trying with a piece of filament if the tube feels rough. In the five years I have had my UM2 I have changed the tube at least once, some times in a desperate attempt to solve an extrusion problem. You have changed all of the other elements in the materiel feed chain good luck
  2. It may be worth trying a smaller nozzle like a 0.25 for instance, sure it will take longer but it could make the difference
  3. I would not worry too much if you can't get it out, I lost one for a long time and replaced it only to rediscover it (inside the print head assembly) months later when I had to disassemble the print head. I do not think there is any risk of it melting
  4. Question are the materials from the same manufacturer ? The blue on is showing under extrusion, maybe try increase the print temperature
  5. I would very much recommend that you contact Carl at 3DSolex directly, his reputation is very high and has always given me excellent service with any problems.
  6. It could be that one of the pulleys that the belts are attached to is able to slip slightly on the metal rods, worth checking that they are all super tight good luck
  7. My pleasure by the way I am also big fan of the Bondtech feeder (I have the QR version), its great to concentrate on design and not printer maintenance
  8. you could try cutting say a centimetre from the end of the bowden tube which should give the white plastic part a better grip
  9. +1 for positive comments on 3dsolex, I have not used a nozzle from Ultimaker for years, especially useful are the ruby/sapphire tipped nozzles for abrasive materials
  10. its hard to say what has caused your problem, have you recently changed the print nozzle ? it could be that it was maybe not tight enough and leaked ? good luck with the test print
  11. nice work - well done - I know what you mean about post processing but your result sets a high bar for bronzefil
  12. you could try re positioning the part to a different place on the bed (left or right), this would prove @gr5 thinking
  13. depending on what you want to achieve with your 3D printing you maybe should start looking into CAD software and try to find one that suits you, I personally am a big fan of Fussion360, but there are many other possibilities good luck and welcome
  14. Hi Curor I would echo the thoughts of @rowiac I started out trying to use Sketchup but eventually fixed on using Fusion360. It has many advantages - its free, has a history feature which means you can go back in time and edit the design, plus lots of training on Youtube. An interesting feature for you is the links to a company called McMaster-Carr where you can download design files for hundreds of items (including many gears) you can edit them to suit your requirements good luck
  15. To help you I would like to see the first movements of the print bed from the very beginning of a print, but I would suggest that the z stepper motor may be wired wrongly. When a real UM starts a print it resets the position of both the print head and the bed, with the bed it should move up slightly and then down to the lowest Z stop position (controlled by the limit switch) I also have no info on the controller board or the firmware release level, I assume its a kit from China ?
