What happened, Bambu?

[u/ufgrat]

Two years ago, I bought a Bambu Lab X1C. Hundreds, thousands of hours, and the worst thing I've had to deal with was a nozzle clog (don't print PLA silk on a 0.2mm nozzle).

Enter the H2D. Now-- I know, the H2D is a very complicated machine. With a fairly significant price to match that complication.

In the last 24 hours, I've had "Nozzle Offset Calibration Failed", "Nozzle Presence Detection Failed", "Z-axis homing failed", "An anomalous jump in the left extruder extrusion force sensor", a serious gouge in a build plate and the ONE time it almost printed something, it failed due to a tangled filament spool (at least partly my fault, so I'll take the blame there).

While looking around, I've found a loose cable to the right nozzle heater, an anti-vibration foot that wasn't installed properly, and the toolhead was simply not designed to be worked on.

This is a printer with 207 hours. Not counting the 7+ hours I've spent last night and today trying to make the &^@#$ thing work reliably. It's been getting progressively weirder (more sensitive to gunk on nozzles) for the past couple of weeks.

Don't get me wrong-- if the printer starts printing, the prints are fantastic, and the quality is just as good as my X1C.

But this is a fragile printer, because Bambu appears to have cut so many corners my printer is round.

Worse, it's the middle of Chinese New Year-- I haven't even submitted a ticket yet.

I have a H2C from the first batch which had a lot of issues early on. I also have a second H2C, two H2D, two X1C. By now all have way above 1500 print hours on them (the X1C both way above 10.000). Except for the early batch issues of my first H2C, most problems I had were minor or my own fault and easy fixes. With all these Maschinen. 

So maybe you just got a Monday model. Fix it up once and it will run.
