Bowden tube noise and play issue. Any help appreciated.

Recommended Posts

I have read other posts but I have not seen an issue exactly like mine.

I am having slight retraction issues (like many others on these forums). The cause of it is on the feeder end (cold end). I have printed the shim found here: http://www.thingiverse.com/thing:46157/#instructions

It still has some play and every time it retracts, it makes a grinding/screeching sound similar to that of a rocking chair. Does anyone else have this issue? Is there a way to orient the tube to fix this? Any help is appreciated. Thanks.

There isn't much room at all. I spaced the mesh so that the teeth were only .5mm apart. I still think that it is the tube moving just a little in the housing. I think this because it would make a worse sound before I printed the shim. I could even see when the noise would start and stop. When it retracted, the tube would move up a little and make the screeching noise. Then, when it extended, the tube would move back down and make a similar noise. Any way I can make it stop omitting such a terrible noise or hold it place better?

    • "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.
