Extruder Jam Issue

Recommended Posts

PLA clogs happening at the PEEK end.

Has anyone been able to find a good work around to this? Its started to become more frequent on my machine, and I have already trimmed the PFA tube twice because the end was too mangled to be reused. I'm at the point now where I will soon have to replace the PFA tube because its going to be too short.

The weak point is clearly the push-to-connect fitting. Its just not able to handle the pressure that's building up while printing at high speeds.

Joergen do you have a none stock PEEK Baffle? The one in my machine just barely sticks up on the inside of the PEEK enough to be flush against a straight cut PFA tube. I could do the chamfering you show in your post however it would not sink around the PEEK baffle as much as it does in your pictures.

Mine is non-stock by now (had to replace the brass tube, but the PEEK is still the original, I left the PEEK away for illustration purposes in the link above), but I think even a tiny bit of chamfering with the original tube will help with the seal... The important thing is that the PLA never ever gets in contact with the PEEK.

    • Print Core CC | Red for Ruby
      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.
