Bambu Lab H2C - Biggest fail printer so far

Bambu Lab H2 Series Bambu Lab H2C

Bought in September and I’ve had nothing but issues. I’ve had an X1 Carbon and still have an H2D which I really rate, but this H2C is a pile of horse manure.

I’ve done multiple two colour prints and two multi colour prints and a ton of single colour ones that took 7 days at a time. I’ve always thought the quality compared to the H2D isn’t as good and recently, it’s just got worse to the point I can’t print anything bar single colour prints.

I’ve had tiny particles shaved off the filament during multi colour prints, creating excessing ‘dust’ in the AMS all due to the prime tower and continual filament swapping - that is going to cause no end of problems soon.

Now four times I’ve tried to print a multi-part file using filament I’ve used before and it keeps failing. One was a random ‘can’t swap toolhead’ error even though there was nothing blocking the toolhead path, and multiple with bits falling off the print, spaghetti failures or the print not sticking.

I’ve seen a lot of loose stringy lengths of filament being left all over the printer, like the ooze lever isn’t operating correctly.

Bed has been cleaned - repeatedly.
Full 30m calibration done many times.
Slowed prints down.

Please come take this back and either give me my money back or a tested, working model please. Really not impressed for the £2.3K I spent on this thing.

How do you dry your filament, how do you know when it’s dried enough, and how do you keep it dry?

What filaments are you using? Type and brand please.

Do you locate your prime tower close to the print, or far from it?

How do you clean your build plates?

What kind of things are you printing?

Have you done a high precision calibration?

Have you done flow calibration tests for the filament you’re printing?

Have you raised support tickets for any of this?

I’ll be perfectly honest, you’re well outside the warranty return window, and none of these things sound even remotely like serious machine issues. We’re happy to help you figure them out though.

The H2C is the most complex printer Bambu makes, it isn’t ever going to be as easy to use as an X1 and I’m pretty sure you have used your H2C in ways you’ve never even try to use your X1 - so that comparison doesn’t work.
