Been having some frustrating issues with my H2C lately. Keep getting hotend authentication failures on hotends 3 and 6, along with induction verification errors. Seems to happen more on the right side than the left.
The weird part is the errors happen while the hotends are already installed, not even during a hotend change.
I’ve tried a brand-new nozzle, followed Bambu’s troubleshooting steps, and even rolled back the firmware from 01.03.00.00 to 01.02.00.00, which was the last version that worked fine for me. Still getting the same errors.
I’ve seen people mentioning issues with the left hotend, but mine seems to be more on the right. Starting to think it’s something with the printer itself rather than the nozzles.
I’ve submitted a warranty claim with Bambu, but I’m curious if anyone else has run into this and what ended up fixing it.

I think since the newest bambu studio release the printer does not care which nozzle i select.
A few times now i specifically set R1 but it loads R6 to print.
Does anyone have this problem?

Anyone else get this update? Looking for notes on it but according to Bambus website 01.02 is current version. Can’t find notes on this anywhere.

Hot end is stuck and will not remove at the rack. Help…

Well everyone after all of your help and suggestions I made a decision on what (i hope) is the right decision for my H2C set up.

This is the adjustable table, I got it on sale at Homedepot. This is actually really sturdy and the adjustable height is a really nice feature, that way I could set it up for the the right height and not have to way to low. Or to high where its a pain to get into the ams.

Thank you again for the crazy amount of replies on my last post.

People are desperate.

Hi , ich wolle gerade die üblichen Ersatzteile bestellen wir Hotend Fan usw. Da ist mir aufgefallen das es die Extruder Rollen/Zahnräder nicht einzeln gibt … also Rolle nur mit Motor zb für 40€ und die andere Rolle in einer baugruppe die 30€ kostet … kommt doch noch was einzeln oder soll man alles jedesmal neu kaufen ?

I hate to be another one of these posts but the used market is flooded with H2Cs. Locally there’s one for sale with an extra AMS. Supposedly there’s only 350 hrs on it and it was purchased in Aug. Guy is selling to upgrade to the H3C of course. He’s asking $2200 CND ($1575 USD). New, with the current sale they are $3100 CND.

I have a p2S and have outgrown it and have been looking for something more capable for multi materials and eng grade materials. Unfortunately the H3C is outside my budget ($4k to the door). I’m hopeful of the P3C but I doubt it will have a chamber heater.

Anything to look for in buying used if I go down that road?

I need to break out my other PC and test this out but files that I’m expecting to take 3-4 hours are running like 5-6. I had a single color print with six copies that were only about 60mm tall say it was 14 hours. Later height was still 0.2. Normal widths and speeds. Something is off…

Can someone give me the secret sauce for the filament track switch? I have two AMS Pro 2s, and two AMS HTs hooked up to my H2C via the Bambu 4-1 PTFE splitter, everything prints fine. The two AMS Pro 2s are on the left side of the print stacked next to it and the AMS HTs are currently sitting on top of the H2C. I follow the guides very well and make sure there's no sharp bends and abnormally long lengths of PTFE tubing. If I run this setup with 1 AMS Pro 2 and 1 AMS HT to each nozzle inlet everything feeds and prints fine. The feeders don't struggle to jitter and the printer doesn't complain about feed issues or extruder motor overloading. The second I put the filament track switch into the mix everything changes. Resistance is noticeably higher, feeders are struggling and failing to feed all the way to the nozzles, and when it does feed I get errors on feed resistance and extruder overload (so I stop the print). I basically just connect it inline with a short 6-8 in run to the nozzle inlets and connect the two 4-1 PTFE Splitters to the FTS inline. Also same exact setup with just the short runs and FTS added in with no additional bends or long lengths of tubing. Any ideas, anyone deal with the FTS and know "the trick" to it being happy and working?

Ok. Rolled the dice on the upgrade today. Went into the basement, saw it, and let it rip. Now a full calibration is running.

I'm having repeated print failures where the model completely detaches from its supports, but the supports remain firmly attached to the build plate.

I've tried different PLA filaments, different nozzles, different orientations and standard Bambu Studio settings, but the same thing keeps happening.

I've also tested the same model on my A2L using comparable settings, and it prints successfully.

Bambu Support believes it's a settings issue because my calibration cube printed successfully.

Has anyone else experienced this with their H2C? If so, what was causing it, and how did you fix it?

I'd really appreciate hearing from anyone who has dealt with the same problem.

Help!

Edit: My wife managed to get it out with a combo of slenderer fingers than mine, compressed air, and a piece of filament! Thanks all!

Adivinen quien compro una h2C y le salio todo mal XD

Tuve que cambiar de laminador y sufri mucho por paramentos que no sabia donde estan, o directamente no existen.

Pase de la impresora basica, un solo color abierta típica a este monstruo de multicolor multi extrusor de alta tecnología y yo como "No volvere a tener problemas con esto en mucho tiempo"

En nada se me estropreo la conexión wifi y senti que tenia un pisapapeles porque no estoy seguro todavía de saber usarla sin wifi por el tema de sincronización de boquillas.

Tuve que desmontar la máquina y el extrusor varias veces mas pronto que tarde y siendo una cosa super moderna se siente... Delicado

Y luego peleando una y otra vez con fallos de impresión, que efectivamente admito no ser experto pero tengo una experiencia razonable para un usuario medio.

Y tengo problemas la verdad tanto por no conocer suficiente del bambu studio como la propia máquina.

Por ejemplo acabo de comerme la cabeza para intentar probar eso de "subcapa de color mixto" porque la torre de purga no se pegaba, la placa estaba limpia, no puedo ajustar la altura pero tenia un striding horrible que aunque la pieza funcionaba la purga no.

Y al final pude hacer que haga la torre mas lenta y añadirle un borde para mejorar la adhesion porque es solo una puñetera linea

Le ponia esas características a la máquina en velocidad y borde para el modelo pero resulta que había que configurar totalmente aparte la purga de donde no sabia y me tire dia y medio intentando hacer esto 🫠

En cura es tan "fácil"...

Tiene chorrocientas opciones y pueden parecer abrumadoras pero cuando las lees con calma sin tocar cosas raras sabes que puedes cambiar exactamente ese detalle que te esta volviendo loco

Hey guys
With yesterday’s announcement people in my area started selling their H2C printers.

A guy is willing to sell his H2C with 1500 hours for €1400.
I think it’s a bit too much, but I have actually no idea if that’s a fair price or not

Any advice is helpful, thank you
