Sqeaking sound from extruder Bowden tube coupler

Recommended Posts

You need one of these. It will also help your results when using retraction since it takes the play out of the bowden tube.

I tried to see if there was a version of it on Youmagine, but I went to the home page - and there is no search button!

edit-

I didnt want to link to Thingiverse again. I went to the YM home page and I was surprised to find no search button on the home page. I guess I was too easily discouraged so I went and found the link on Thingiverse. I did later find search from one of the secondary pages. It might be better you could search from the main page

Well tonight I went to print that part and had a little catastrophe of sorts.

The Bowden tube popped out from the print head during the print. When I came to check on the print, I had a quite a sight!

I can't seem to get it aligned into the hole quite right while everything is mounted, so I may have to remove the print head assembly from the axes. Which makes me wonder if I may as well install the second print head since I have the kit. I may not use it right off, but while apart....why not?

Bummer. I'm thinking maybe your head is cooler than the UM is reading so you might want to raise temps by 10 or 20C next time. And/or slow down the print some more.

If you unscrew the brass nozzle, make sure to heat the head to 180C or so first and be very gentle. Brass is not very strong and many people have twisted it into 2 pieces. Not fun.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
