Ah, the joys of 3D printing. One day, your Bambu Lab X1C is churning out beautiful, crisp prints like a dream, and the next? Well… let’s just say it starts acting like it has a mind of its own. That’s exactly what happened to us. What started as a minor issue with thin walls collapsing quickly spiraled into a full-blown case of “Why won’t anything print properly anymore?!”

If you’ve ever faced a situation where your printer goes from perfection to catastrophe overnight, you know the frustration. But instead of panicking (okay, maybe after panicking a little), we rolled up our sleeves and went full-on detective mode. Here’s what we tried, what worked (or didn’t), and where we ended up.

The First Sign of Trouble: Thin Walls Collapsing

The first red flag was when we printed a simple container model—nothing fancy, just a basic boardgame insert for Clank! Catacombs. But the walls were way too thin, and they collapsed like a soggy house of cards. At first, we thought, “Maybe it’s just a slicer issue?” You know, some setting we accidentally messed up.

So, we re-sliced the model, double-checked the wall thickness settings, and even tried printing a different design. But nope—same problem. And then things got worse.

The Snowball Effect: Failed First Layers

Soon, the printer wasn’t just struggling with thin walls; it was failing right from the get-go. Prints wouldn’t stick, the first layers were inconsistent, and some prints didn’t even start properly. That’s when we knew we had a real problem on our hands.

Now, if you’ve been 3D printing for a while, you know that first layers are everything. If the first layer goes wrong, the whole print is doomed. It was time to start troubleshooting.

The DIY Fixes: What We Tried

We went through the usual maintenance routine, step by step, hoping to breathe some life back into our X1C.

1. Cold Pulls – The Classic Unclogging Trick

A cold pull is a simple but effective way to clear out gunk from the hotend. We heated the nozzle, pushed filament through, let it cool slightly, and yanked it out to pull any debris along with it.

Did it work? Not really. It pulled out some residue, but the problem persisted. On to the next fix.

2. Hotend Deep Clean – The Fire Method

Alright, time to get a little more aggressive. We disassembled the hotend, heated up a piece of filament with a lighter, and used it to stick and pull out stubborn debris. It’s one of those old-school tricks that sometimes does wonders.

Success? Meh. Some filament chunks came out, but the printer still wasn’t happy. At this point, we were starting to get nervous.

3. Extruder Cleaning – Going Deeper

Next up, we tackled the extruder itself. Maybe there was filament dust or debris causing under-extrusion? We took it apart, gave it a deep clean, and reassembled it carefully.

Results? Nope. Still the same frustrating print failures. It was becoming clear that this wasn’t just a case of a dirty nozzle or extruder.

The Last Resort: Contacting the Seller

After exhausting every trick we found online, we had to accept the inevitable—it was time to reach out for professional help. We contacted our local seller, explained the issue, and now… we wait.

The waiting game is the worst, especially when you’ve got projects lined up and a printer that refuses to cooperate. But sometimes, 3D printers just need a deeper repair that goes beyond routine maintenance.

Lessons Learned (So Far)

This experience has been a rollercoaster, but it’s taught us a few important lessons:

• Even top-tier printers like the Bambu Lab X1C can run into issues. No printer is invincible, no matter how good it is.
• Regular maintenance is crucial. Even though our fixes didn’t solve the problem, keeping the hotend and extruder clean can prevent smaller issues from turning into bigger ones.
• Sometimes, you just need outside help. There’s no shame in reaching out to experts when troubleshooting hits a dead end.
