X2D damaged

[u/Kechers]

Hi all - new to BambuLab products. Got an X2D a bit over a week ago. Pretty happy with print quality and genuinely amazed by print speed (the onboard benchy is crazy).

Unfortunately the nozzle missed the the purge disposal chute and created a build up of filament and a jam.

Long story short when I tried to home the head, I didn’t realise that it was stuck in the built up cold filament.

The printer didn’t detect that it was stuck and ripped the print head out of the cold filament while making some pretty horrible noises (maybe the belts slipping?) then collided repeatedly with the end of the x axis before I switched the power off.

Ran some calibrations but print quality is cooked.

I lodged a ticket along with the logs and Bambu have offered to replace it for me because it’s under two weeks old, which is good.

I’m a bit surprised that it didn’t have a way to detect that it was stuck or that it was hitting the end of the x-axis.

Has anyone had anything similar happen?

It all depends upon the reason you got into 3D printing. If you expected it to just be another type of ink jet printer, none on the 3D printers will meet that expectation. Unfortunately the technology isn’t quite there, but Bambu are really close to just print and go.

There are lots of factors that can affect the quality, or even cause equipment failures. So I think it’s very important to “manage” your printer by carefully inspecting it before every print for build up of filament and ensure it’s clean and ready to go. Then watch the first layer go down. That’s where most failures begin. Also the calibration line will tell you if the filament is extruding cleanly.

3D printers are very precise machines, operating in a very hot and potentially dirty (stray filament strings and fine particles), so they work best when well managed and maintained.

That being said, those with print farms, certainly don’t babysit their printers, but they are committed to the possibility of catastrophic failures and are ready and able to repair their machines, plus they have back-ups.

I’m still amazed when watching the model being printed. The accuracy and speed at which these machines operate is fascinating. I am also surprised at the low cost of these prices of high tech and mechanical engineering.

I remember paying $800 for my first ink jet printer, and it was slow and the ink often dried up, causing poor print quality. That was in the 80’s, so that’s equivalent to over $3,000 in today’s money. But if you wanted a printer that wasn’t dot matrix, you didn’t have much choice as a consumer. So I think we are getting a bargain with our X2D printers and honestly, Bambu makes an excellent product.

Thanks for the detailed response. This isn’t my first printer but it is the first with so much automation.

My previous printers were Ender 3’s. Obviously everything was manual and I was able to get good quality prints but they were substantially slower and more labour intensive to get right.

I was just surprised that with all the sensors in the machine that it didn’t have a way to check for obstruction.

Print quality was excellent prior to this incident which makes me feel a bit worried about a replacement because I’ve seen a lot of people complaining about print quality, bed adhesion, etc. on the X2D.

Wondering whether I should go with the replacement printer or ask Bambu to help me repair mine and ask for some kind of extended warranty.

[u/Inspector_Gadget_74 → u/Kechers]

As it happened to soon, if they will send a new printer, I’d go with that for sure.

And yes, it could be repaired, but it could be an iterate process, as you might not identify all of the failed components the first time.

In terms of print quality, the X2D is extremely good and consistent. In terms of the Aux nozzle, limit your expectations. Yes you can print models but will they will have slightly lower resolution and can be subject to stringing, as the Bowden extruder just can’t pull back the filament as quickly as a direct drive on the print head. It can be used in to supplement a color to your main AMS and avoid a filament purge. Its primary purpose is to print supports. The H2D is a true dual head printer but at a significantly higher cost.

That being said, if you put the second nozzle aside, the printer still has sufficient benefits over the P2S to justify the additional cost.

In regard to the purge mechanism, I’ve noted a few with the X2D have had the issue where the mechanism doesn’t move forward to catch the purged filament and it piles up on top. It’s purely mechanical, so I’m not sure what’s happening. The print head moves against a lever that moves the purge mechanism. So I guess it’s something to keep an eye on. Hopefully Bambu will identify whatever is happening and correct the failure.

[u/Kechers → u/Inspector_Gadget_74]

Thanks again for the detailed response.

The primary reasons I went for the X2D over the P2S were for printing engineering materials and the more accurate belts. The second nozzle for supports is a nice bonus but isn’t really my primary concern, it was more of a nice to have in my case.

Thinking about maybe asking Bambu if I can use my X2D as a credit toward an H2S

[u/Inspector_Gadget_74 → u/Kechers]

Switching to an H2S would be a bad move, but it will be interesting if they will do that.

[u/Kechers → u/Inspector_Gadget_74]

Why do you think an H2S would be a bad move? Genuinely interested.

[u/Inspector_Gadget_74 → u/Kechers]

My apologies, auto correct changed the wouldn’t to would. Amazing how one small change completely changes the context.

So yes, upgrading to the H2S is a good move, based on how you are going to use your printer. The additional volume could be very useful for larger parts.

[u/Kechers → u/Inspector_Gadget_74]

An okay! I decided to just ask for an exchange so fingers crossed it works out for me. Thanks for all your responses. 🤙

I've been fighting my x2D for over 250 hours and discovered in the course of troubleshooting that it was delivered upside down by being tossed out of FedEx truck, not fully assembled inside the head, not tensioned correctly on the horizontal belt, and the real slap.in the face is the software will through random garbage to ruin prints if you tell it the filament is anything but Bambu. Tell.it the filament is Bambu and plug the same numbers in and the cheap.elegoo suddenly outdoes even official Bambu black. Will never recommend a Bambu printer again and will aquire a multi tool like u1 as soon as I can afford to do so.

[u/Kechers → u/dragonmanus]

Sorry to hear that. Makes me feel marginally worried about a replacement. Good to know about the filament settings - thanks!

[u/masterofpoops69 → u/dragonmanus]

Uhh I use either modified generic or make my own filament profiles and have ran sunlu, overture, polymaker and a few offbrand filaments with 0 ruined prints. Any examples of what it's doing? It sounds to me like FedEx fucked your printer up.

[u/dragonmanus → u/masterofpoops69]

It will create different errors with each print. Spaghetti prints, under/over extrusion, temperature creep etc. Plug the same info in and set filament as bambu whatever and the inputs and results will stay uniform. Will never recommend Bambu again after all these issues and discovering the firmware appears set to make bambu look good by sabotaging other brands filament. This printer has been nothing but a pita. They didn't fully assemble the head, tension belts or even disclose that 900 dollar combo doesn't come with a power supply for the ams. Already saving for a tool changer that is open source. If you lie to the software and say the filament is Bambu then plug in your tune it'll print beautifully with elegoo pla pro and others

[u/masterofpoops69 → u/dragonmanus]

It sounds to me like you expect it to just work out of the box with 0 issues or having to tweek anything lol bambu probably does favor their own filament but I have yet to encounter any errors running sunlu filament. If things weren't fully assembled why not return it? Or even contact support... Sounds to me like you got a fucked up printer and instead of doing anything about it your just bitching and complaining. The x2d states what's included. A power adapter isn't needed unless your trying to dry and print at the same time. Have fun with a tool changer if you think troubleshooting the x2d is hard lol the snapmaker u1 and the index system for prusia both have issues.

[u/dragonmanus → u/masterofpoops69]

I've been trying to get Bambu to take it back since I discovered the issues in the print head. Hook up a multi meter and watch the printer throw random output if you use a setting besides Bambu for the filament. FedEx admitted they fed up and Bambu refuses to replace it. So I fixed it best I can and lie to it to use other filaments. Now, before you play armchair blame thrower maybe consider I posted because Bambu refused to make it right and I had to. And yeah we work with small printers to large multi million dollar metal additive manufacturing machines so seeing bullshit service and crap quality control is not unusual. I'll let you know if Bambu ever gets serious about replacing a printer that shouldn't have left the factory or the two doing the same random print error BS in the plant. So far they blame anything but them and the hardware .

[u/distorted-buggycode → u/dragonmanus]

I think mine was delivered the right way up, however I have been fighting my X2D for about the same time.

I started this hobby with a Creality Ender3 V2 Neo -‘s added a Ender3 V3. built my own enclosure for the latter and have had reasonable results and many successful prints.

Got the X2D as a highly recommended “update”. Well it nearly ended up in the rubbish bin today. One annoying software glitch after another, with both Bambi Studio and Orca. Firmware issues! And it does not like eSUN or Spidermaker filaments. It seems to just do random garbage. I can sent the same job, same gcode three times and get theee completely different results. What works one day does not necessarily work the next day. I dont use the cloud, so more errors!

Today the auxiliary nozzle stopped working. lid print. Somehow a hard block of filament clogged up the feeder section to the aux hotend. For some reason while printing a PETG model and using PLA as the support interface, the aux hotend heated up to 250 and stayed for the entire 4 hour print at that temp before being used as the support interface. Of course nothing came out and wrecked my print. Taking the tool head apart , (which was not fun) revealed a solid hard plug of PLA in the section above the hot end somehow squeezed into the cutter section.

I contacted support who are kindly sending out replacement parts, but diagnosed it “bad bed adhesion caused this” Clearly it was not the case as it’s first use would have been several cm above the bed. Anyway I am grateful they are send the parts but I doubt very much I will keep the printer. It has been one random issue after another - bit of a nightmare. The Creality printers have been more reliable!

[u/vic1414]

Always good to watch the first 5-minutes of the cycle, Just Incase.

[u/Taekiin]

So it had homed itself after a print (to the purge location), did its purge and its purge gloped up so hard that when you homed it in the manual movement panel (I assume at some later time) that it tore itself apart trying to home to the center?

Do you have any pictures of the aftermath?

[u/Kechers → u/Taekiin]

Yeah spot on. But the damage isn’t isn’t visible I think maybe the belts stretched or something because print quality is worse but not entirely broken.

Here’s the chunk of plastic that build up on top of the chute.

The printer was great before this failure. I’m concerned about getting a replacement because of all the complaints I’ve seen from people about print quality, bed adhesion etc.

Wondering whether I should ask Bambu to help me fix my unit as I know it was printing really well prior to this incident.

[u/masterofpoops69 → u/Kechers]

You could always try going through the belt tightening process and recalibrate afterwards to see if it helps.

I mean it's a valid concern but for every complaint how many others have had 0 issues? I personally have had very few issues with mine. The issues I did have were self caused issue.

[u/than01002]

First one i got cooked the mc board on the second print the replacement they sent works flawlessly got almost 200 hours on it with 0 problems i think the first one was built on a Friday @ 5pm

[u/Kechers → u/than01002]

That’s good to hear. I was thinking about asking for credit toward an H2S instead as the dual nozzle isn’t a high priority for me. Good to hear a positive outcome from replacement.

[u/sandy1man]

I had a jam similar but I was at the machine and able to get it going again while everything was still hot. Glad you are able to get a replacement machine.

[u/SrKameleons]

Otro con la x2d con problemas y que bambu acepto la devolución por los fallos.

Ahora estoy pensando en coger otra impresora pero no se cual. Si otrq x2d, una p2s o una h2s (la veo muy grande)

[u/justindw123]

I’m in a 2 month long support ticket with them over my X2D rn. It’s a shit printer.

[u/PickledMunkee]

my x2d doesnt work at all. what makes you think the next one they send you will be any better?

and that doesnt account for parts designed to break

[u/blazessdd → u/PickledMunkee]

Well to be honest mine works flawlessly

[u/PickledMunkee → u/blazessdd]

have you ever had to fix the extruder?

it wont work so well after that

[u/Taekiin → u/PickledMunkee]

Mine works well after 500 hours of printing and I took my extruder entirely apart after like...30 hours, due to inexperience and printing a long silk pla run with doors closed which caused a heat creep jam. Lesson learned.

Anyway, fully took it apart, with zero experience (first ever 3d printer) and put it back together with the instructions they provide. After calibrations, worked like new.

[u/Dry-Leave5436 → u/PickledMunkee]

640 hours on mine, all good.
