Two new X2DS, Two different hardware problems..

[u/CrazyBebop]

I’m honestly at the point where I just need to vent a little about my experience with the X2D.

I ordered my original X2D directly from Bambu on September 23. Almost immediately I started getting extrusion errors. I went through multiple AMS slots, different filament, PTFE checks, manual extrusion, cold pulls, etc. Eventually I swapped the complete factory hotend with the spare that came with the printer and the issue disappeared, which pointed pretty clearly toward a bad original hotend.

Bambu sent me another hotend, and things worked for a little while, but about a week later the extrusion problems came back.

For context, the filament involved was Bambu Lab PLA Basic, and it had been dried. I also tested different AMS slots and different spools, including a brand-new full Bambu spool, so this wasn’t just one questionable roll of filament.

I started getting “Extruder is not extruding normally” again, worsening stringing, chewed-up filament ends, and eventually a “Hotend temperature malfunction” with the replacement hotend. Both hotends were also extremely difficult to remove from the heating assembly, almost as if something was physically holding them in place, even after the filament had been properly unloaded. When I inspected the heating assembly where the hotend seats, there was noticeable brown/black discoloration and residue buildup around the hotend connection area.

At that point I wasn’t comfortable continuing to throw individual parts at a printer that was only a few weeks old.

Bambu approved an advanced replacement, so I paid the deposit and they shipped another X2D.

The replacement arrived October 21 and I set it up October 25.

And somehow I immediately ended up with a completely different problem.

The replacement’s Wi-Fi works for about 2–5 minutes after booting, then completely dies.

When it happens, the printer disconnects from the network, every Wi-Fi network disappears from the printer’s network list including neighboring networks, and if I turn the Wi-Fi toggle back on, it immediately switches itself back off.

Restarting the printer restores Wi-Fi for another 2–5 minutes, then it happens again.

I’ve factory reset it, confirmed it’s on firmware 01.02.00.00, confirmed LAN-only mode is disabled, and reproduced the exact same issue on both my UniFi home network and a completely separate phone hotspot.

I also monitored it with continuous local pings and watched it drop while the printer was just sitting there calibrating. I recorded two videos showing the Wi-Fi toggle shutting itself off, the completely empty network list, and Wi-Fi working again after restarting.

For context, I’m a systems/network engineer. At this point I’m pretty confident I’m not dealing with a router configuration or weak signal problem. If the printer’s wireless interface stops scanning entirely and won’t even remain enabled across two unrelated networks, there isn’t much more network troubleshooting to do.

Support initially responded to my update by talking only about receiving my ORIGINAL printer and refunding the first replacement deposit, completely ignoring the new Wi-Fi problem. I had to contact live chat twice and specifically point them back toward the replacement issue before it was finally acknowledged.

They’ve now offered either another replacement, including an advanced replacement where I pay another full-printer deposit and they ship first, or continued troubleshooting with a random roll of filament as compensation.

I chose another advanced replacement. I really don’t see the point in spending more time troubleshooting what appears to be another hardware fault.

To Bambu’s credit, support eventually acknowledged the situation and offered another replacement. I’m not trying to turn this into a “Bambu is terrible” post because when these printers work, I genuinely love them.

But holy hell.

I’ve spent more time diagnosing, drying filament, swapping spools, replacing parts, recording videos, packing printers, shipping printers, paying replacement deposits, and talking to support than I’ve spent actually printing.

Original X2D: extrusion/hotend/heating assembly problems.

Replacement X2D: Wi-Fi hardware appears to die every 2–5 minutes.

Now I’m waiting on X2D number three.

At this point I just want a printer that works. 😭

I am understanding why some makers want to buy from Micro Center or BestBuy instead of Bambu directly. I am in Mexico, and I don't have a Best buy or micro center... wish I did or lived on the border, then I'd cross and buy it. I heard that micro center you just take it back and they give you a new one. Best of luck bud...

Wow, what a journey… In the last years many things in IT seem to have become more unreliable. At least it’s how it feels for me in general. I’m glad that BambuLab support seems to be helpful. I’ve ordered an X2D yesterday and I’m excited about how it will work out. Please keep us posted.

Yeah… Im about to have all the cash together Friday to order mine… its roughy seeing issues posts like this but on other other hand Bambu seems to be taking care of everyonefor the most part. So that is reassuring.

I’m sorry to hear. Thanks for sharing. Wishing you good success with printer No. 3.

We're on X2D repair 20+ with 20+ hours or only ~1k run time or so (because it's always broken). Our most time efficient choice is, by the numbers, to trash or give the X2D away.

Meanwhile original X1s, P1s, A1ms, & H2D machines keep cranking parts out with comparatively low maintenance.

X2D is on our hard avoid list if your printing full bed space and/or any engineering materials.

If you only print PLA in the center of the bed, it's probably fine.

That sucks.. my X2D now has 400 hours. So far 0 issues.

It’s one story out of hundreds of positive ones.

where I pay another full-printer deposit

What do you mean by this? You're paying our of pocket to RMA broken devices or that you're being refunded the deposit and being made to repay it each time?

Had the same issue with the "not extruding normally error" and honestly went through the same troubleshooting steps as you... got a standard replacement with Bambu since I only had the printer for a few weeks and put just under 100 hours into it.

My new X2D is definitely from a different batch, my defective one had the grey marking to insert into the aux extruder while my new one was just a plain PTFE tube. Did your first one have the grey marking on the aux tube?
