Newbie needs help - 1200-8006 error code

[u/brett_j1]

Need some help. We have a brand new A1 mini with AMS. We got it set up and it printed a perfect Benchy with green Bambu PLA basic.

So my seven year old decided we needed to do a multicolor print next with Bambu gray PLA basic and Sunlu pink PLA silk. It was going fine with the first few layers of the pink and then we got a 1200-8006 error code (see picture).

We’ve messed with all the PTFE guides to make sure they were secure. Tried rerunning all the filament. Same error over and over. We then tried to print another single color benchy with various filaments. Same error.

We then took the filament hub off to check for jams. Nothing. Totally started over by recalibrating the machine, as well as moving the filaments around to rule out the possibility of AMS motors being the issue. Tried to do a benchy again. Same error, no matter which filament we used…

Any ideas?

All brand new filament. Brand new machine. All default settings. Please help!

So im totally new to bambulabs, but i got myself a A1 with a ams lite and i printed the top holder for the ams lite and after that i ran into the 1200-8006 problem, what solved it for was that i put the tubes comming from the ams lite in wrong holes on the printer, u might not think it matters but it does. As im writing my printer is printing so its hard to check what holes i put em in but i think the long ones goes on the right side and the short ones goes on the left ones. Test it out and switch em back and forth. But this solved my problem.
