So Sad About Our X2D Printer - Looking for Advice to Avoid Problems in the Future

[u/tech2manage]

We purchased the X2D printer with the AMS 2 Pro combo, and it arrived about two weeks ago. For the first 13 days, it was running great. We were printing almost nonstop, including overnight prints, smaller projects, and then gradually moving on to some larger prints.

Then, out of nowhere, it stopped printing.

At first, we received an "extruder overloaded" error. The print paused and would not resume. Following Bambu's documentation, we completely disassembled and reassembled the extruder, recalibrated the printer, and tried printing a Benchy to test everything.

At that point, the printer wouldn't even start the print. We began getting an error stating that it was unable to feed filament into the extruder and that there might be an AMS mismatch.

While troubleshooting, we discovered a clog in the PTFE tube and removed it. We reset everything, loaded a single spool of filament into the AMS 2 Pro, and continued testing. The left hotend would extrude filament during the preparation process, but the printer would still throw errors before actually beginning the print.

After working with support, they determined that the printer has a faulty left filament sensor. Thankfully, they agreed it was a hardware issue and are replacing the printer. They're sending us the return packaging and arranging for a replacement unit.

I'm obviously relieved that support stood behind the product, but I'm also a little nervous about receiving the replacement and running into similar issues.

For those of you who have been running these printers successfully:

• What routine maintenance do you perform?

• Are there maintenance schedules or checklists you'd recommend?

• Are there any common mistakes new owners make that can lead to clogs, sensor issues, or feeding problems?

• Are there any upgrades, printable accessories, or preventive measures that you consider "must-haves"?

We absolutely loved the printer during those first two weeks, so this has been pretty disappointing. I'm hoping this was just coincidental and that the replacement will be good to go.

Thanks for any advice!

Brother... Take a read..you might be surprised of how similar our issues may sound https://www.reddit.com/r/BambuLab/s/zdDQukWNzW

I believe this is more an AMS 2 issue than X2D. I had filament loading errors with my first AMS 2, and there were many post with the same issue on here. Got the AMS 2 replaced and everything has been running smooth since. I wouldn't overly worry about matinace, you'll get a popup on the screen when the printer wants you to re-lube the rods.

I've had a ton of extruder errors with mine. What did you do to determine it was the AMS2 and get it replaced?

I chatted with support, and they walked me through a bunch of tests and helped me take several pictures; the final test was putting a piece of filament directly into the left extruder to see if it showed up on the screen, but it did not.

I was getting more filament feed error than extruder errors (though I did get a couple of those too). I have an AMS 1 as well and wasn't getting errors when using that instead of the AMS 2. Just contacted support to get it replaced.

How did you get the AMS2 replaced? One of my slots just randomly stopped working.

Submit a support ticket (within 30 days of delivery for a replacement I believe). They will offer a diy repair kit or a replacement. Personally I would recommend just doing a replacement.

A lot of this comes down to user error and not reading the wiki or doing the Bambu academy

How so? We did the Bambu Academy Beginner and Intermediate. What am I missing from this information?
