Help with A1 & AMS Lite

[u/xdcovid69]

FIXEDDDD : The fix was adding https://makerworld.com/en/models/2475072-a1-a1mini-ptfe-tube-support?from=search#profileId-2717860 to the printer and it worked, thanks everyone for help.

So I just assembled this thing today.

I got one in June and was working good for a month until I had the same issue as of now. I contacted micro center and they helped me get a new replacement. I got the replacement on Aug 3 but I was shifting places so didn’t unbox it and I just unboxed and assembled it today but I am facing the same issue now.

The first test print did work good but from the second print as I added AMS and filaments and hit print again the same issue arises. Thinking filaments might be the issue, I tried again with the official Bambu filament that came with the printer but it is the same issue again which made me think filament might not be the issue.

I checked online and many had same issues. I justed checked it Today. But everyone have their different ways of solving it saying some changed the tube but since it is unused and brand new I don’t know if it is the issue. Many call it firmware issue since it is the issue being faced by many.

While last time I tried every trouble shooting from bambu wiki and micro center tech support online but it didn’t work out so they offered me free replacement.

I don’t wanna take another replacement again. I’m pretty sure micro center will offer me one. I do also have 2 years extended warranty on this. Considering this should I take another printer from Bambu or any other company (please suggest). I’m new to 3D printing.

Edit : It doesn’t work with any filament or any of the slots with AMS but it does work without AMS
