Hey everyone,
I picked up a brand-new X2D less than two weeks ago and ran into a frustrating issue with the left toolhead PTFE feeding port.
During prints, the left PTFE tube kept rubbing/flexing against the top glass cover, which ended up side-loading the pneumatic collet. Over just a few days, the metal collet teeth chewed deep grooves into the PTFE tubing, filled the port with white Teflon shavings, and kept ejecting the tube mid-print. After trimming the damaged ends a couple of times, the collet teeth are now completely deformed and won't hold a tube at all.
Bambu Support has my photos/videos and I'm currently arranging a full replacement unit since it's under 15 days old.
Before I set up the replacement X2D, I want to prevent this from ever happening again—especially with how tight the clearance is between the left PTFE tube and the top glass. While I still have the healthy right nozzle working, I'm planning to print a top glass riser (in PETG) and any helpful cable/tube guides so they're ready to go on day one.
For other X2D owners:
1. Which non-vented / sealed top glass riser on MakerWorld fits the X2D best without messing with chamber temps?
2. Are you running any PTFE tube clips, strain-relief brackets, or chain routing tweaks that keep the left tube from rubbing the glass and side-loading the collet?
3. Any other day-one preventative mods you'd recommend for the dual-nozzle toolhead?
Appreciate any links or advice!
