So I got an issue today.
My filament doesn’t go past the “rubber” grommet at the top of the printer when switching filament. It goes out the ams, goes through the middle/center part, goes back up, then block and the ams retract the filament and does this 2-3 more time and then stop and call an issue with the filament.
Tried a different spool, didn’t work,
Tried un plugging and plugging back in the ptfe tubing, didn’t work.
What should I try next?
When asking for help, please provide as much information as possible about your inquiry.
Including pictures and detailed information about the print speeds, filament type and settings used will help get the appropriate solutions.
That particular tube join can be problematic. It may help to draw a line with a marker on the tube right where it goes in and then see if you can get it to go in further.
And those fittings need to be worked by using all three hands. One to hold the connector body, one to push the black release fitting as far as it will go into the connector body, and the third hand to push the tubing home.
It’s tricky to do with two hands but can be done. If you don’t push in on the black release ring, the tubing doesn’t like to go in. You may be able to push it harder and get it in, but the teflon is slick and there’s not much there to grab.
If the tubing doesn’t go all the way into the connector body, the filament end may hang on the ledge that acts as the tubing stop and not go farther.
Also make sure there are no burrs or other issues at the end of the filament.
Just curious - what color/brand was the filament that broke?
Reason I asked is people are seeing issues with Bambu Basic Jade White and Black. Poor print quality, slightly different colors on problematic rolls, and brittle filament that breaks in the filament path.
Probably left in the open during a year, but I was in a hurry, and didn’t cut off the first cm, and they’re was a very small blub, that I guess got stuck and when the ams retracted it, broke.
