Dear customers, We’ve heard from a number of you recently that the gears on your AMS 2 Pro Feeder Units are wearing out faster than expected. After digging into the issue, we found that a batch of AMS 2 Pro Feeder Units made between May and July 2026 didn’t get enough grease coverage during production, which is causing this faster wear. The good news is there’s no such issue with units we’re selling on official stores right now. We know this is frustrating, and we’re so sorry for the hassle this has caused you. We can’t say for sure exactly how many units are affected, so we’re making it right for everyone in this batch to make sure no one gets stuck with a problem down the line. Here’s what we’re doing for you: - 4 brand new AMS 2 Pro Feeder Units, on us. We’re covering all the cost of the parts and shipping, so you don’t have to pay a cent. Right now we’re getting all the parts prepped, so the new units will be sent out in batches over the next 3-5 weeks. If your current feeder is still working fine, you can keep using it until the new ones arrive, then check how worn your old one is before you decide to swap it out. - $20 discount code for your next Bambu Lab purchase. The exact amount will match the equivalent value for your local currency. - Extended warranty for your new feeders. When you get the new units, your 3-month warranty will start fresh from the day you receive them. Swapping out the feeders yourself won’t affect the warranty on the rest of your AMS, either. We’ve already sent a message with step-by-step replacement instructions to everyone in this batch through MakerWorld and Bambu Handy. If you didn’t get that message but think your AMS 2 Pro might be part of this group, you can check the wiki guide to confirm. We’re really sorry again for the inconvenience this has caused you, and we’re working hard to make sure this kind of issue never happens again. If you have any questions, please reach out to our support team and we’ll help you sort it out.
