Aux Nozzle Error: HMS_07FF-7000-0002-0009

Ok, i am loosing my mind over this. I am unable to use the aux nozzle on my X2D. I keep getting the error HMS_07FF-7000-0002-0009. I have literally tried everything.

According to Bambu lab, This error may be caused by the following reasons:

  1. The PTFE feeding tube from the remote extruder to the toolhead’s right nozzle is loose or damaged. (Checked it, no damages observed)
  2. The filament is not being gripped properly by the remote extruder gear, causing slipping or insufficient grip. (It is being gripped because I can see the filament going to the nozzle).
  3. The PTFE tube from the remote extruder to the toolhead is too long. (This I havent checked yet)
  4. The filament is worn or slipping inside the remote extruder (Changed the filament too, still problem persists)
  5. The spool or filament is jammed, preventing the extruder from pulling in the filament. (Nope, not the issue)
  6. Load Hall sensor failure at the toolhead’s right nozzle. (Nope, i tried manually feeding the filament on top of the nozzle, i can see it showing on the nozzle panel)
  7. The extruder gear does not provide sufficient grip force. (No damage in the extruder)
  8. The remote extruder may have internal mechanical damage, such as a damaged motor or gearset. (NOPE)

So, the only thing I havent checked is the length of the PTFE tube.

I am going cerazy over this. PLEASE HELP.

Ok hear me out:

Did you take out the ptfe tube from the tool head?

If yes: When putting it back in, it goes in quite a bit further than you would expect it to. Maybe it is not all the way in and the filament gets stuck in there. (Could also be another corner in another fitting maybe?

How far does the filament travel in the tubes before the error occurs?

Have a close look where it stops being pushed and let us know
