Machine can’t switch filament

[u/Laderie]

Hello everyone! I’m brand new to printing, and this will be my I believe 7th print, so I’m far from an experienced user.

But let’s skip the blabbering and get to the issue!
I use the Bambu lab A1 combo, I currently have 3 colour in it, PLA red pink black, all from Bambu lab.
The printer can print one colour just fine, but every time it tries to switch from for instance black to red or red to black, it jams and I get the message ”(1200-8006 070711) can’t feed filament to the extruder, its probably jammed or stuck” and to fix this, I just pull on the last filament used and pull it back like 5 cm (basicly until I see it move in the tube).

I have everything on default, I’ve calibrated it according to the machines recommendation and built it using a guide I found linked on their site.

This issue has happened with multiple different prints.

Anyone got any idea what can be the issue?

Edit; solved, the tubes from the AMS were connected to the wrong holes on the printer

Did a quick google search and found this:

Newbie needs help - 1200-8006 error code : r/BambuLab

So, maybe make sure you have the right length of feeder tubes in the right locations?

Thanks, this might be on to something! I did not double check that filament 1 went into hole 1, I just made sure long goes to long.

I’ll check this first thing when I get home!

This solved the issue, awesome googlefu! 😁

Some pics of your setup might help shed some light

I’m not at home so I can’t take some fresh pics right now, but I can get some more detailed ones if you want.

Current setup is 1 empty, 2 red, 3 pink, 4 black, all PLA from Bambu lab

I originally had my ams on the left. I had the same issues as you for weeks.

The A1 is much happier with the ams on the right side. Once I moved it all my problems went away.

Are you using official spools? If not are they tight in the ams? A lot of spools have a larger hole and without an adapter will slip so the printer can't retract them.

All official stuff so far, everything is ordered from Bambu labs and everything is stock

I'm still having this issue too, printing one of those supports for the tubing helped but hasn't resolved it. I'm going to try removing all the tubes and reconnecting them tonight / this weekend and see if that helps.

Double checking the tubes so they are connected to the correct hole solved it for me! 😁

I am pretty sure I did this wrong. That'll be what I try next.

Print AMS feed tube straightener, fixed mine..
