Nonstop Nozzle Temperature Error: 0300 8008

Bambu Lab P1 Series Troubleshooting
21

Both the TH and TH cable are brand new with the latest parts they sent. Same issue.

I also suspect something with the main control board, or maybe power supply. Or there’s something shorting out somewhere causing the TH board to get fried. And it started intermittently, but is not permanent to the point where as soon as I boot it up, the TH shorts or similar.

Because this started within a few weeks of owning it, and only after maybe 10 hours of printing. So something that definitely came busted.

Just to add to the saga.

I installed all the new parts they sent (TH cable, thermisistor) and was able to complete one print.

But that’s all I was able to do. Back to the same error [0300 8008].

It’s about to be 3 months with a nonfunctional printer. It’s now been broken 3x longer than it’s worked since I bought it with all the issues I’ve had.

Bambu finally agreed to replace my printer.

I’ve read horror stories of others during the A1 recall, but I’m hoping it goes smoothly and I can get the new one relatively quickly and fingers crossed it’s not another dud.

Has anyone thought to replace the usb-c cable connector

This is what worked for me: I reduced the printing speed by 30 to 50% and was able to finally print without the error popping up. Hope this helps.

Have the same issue, I’m with support now going over same steps … it is not the a cabling issue for sure… Same story like everyone, Did anyone find a permanent fix?

For error, 0300 8008

I got the same error code.

After checking, I found all components work and could connect proprerly.

The only situation of mine is that the nozzle heater fails to heat up and starts to cooling, after the laser scan of first layer when the nozzle fan changes from 0% to 100%.

I solved this error by scaling back the wind of nozzle fan from 100% to 0% and reset the nozzle temperature.

As I reset it to 100% again, the nozzle temperature dereases unstoptably and the error comes out again.

The error first comes from a print failture caused by unclosed door, cold winter make it could not stick to existing layer, so some resin was extrude around the nozzle, get inside the heater. I suppose that the reduction of heater efficacy was the main reason for this error.

Bonjour,
A tous ceux qui sont aujourd’hui confrontés au problème du code 300-8008 xxxx avec leur imprimante Bambu,
je voudrais leur faire part de mon expérience de comment j’ai pu résoudre le problème.
J’ai du procéder au démontage partiel du circuit des tubes PTFE. et de l’entrainement filament dans la tête d’impression
pour retirer des morceaux de filament cassés. Après cette action et pour repartir dans de bonnes condition,
j’ai changé la buse, la céramique de chauffe et la thermistance par 3 éléments neufs.
Au redémarrage, le code erreur 300-8008 xxxx et apparu avec le message: " L’impression s’est arreté à cause d’un problème de températrure de buse"
La tempérqature de buse s’est bloquée à 90°C et la tête d’impression s’est positionnée au dessus de la purge.
A chaque tentitive d’impression, j’avais la même situation.
Avec les conseils de BAMBU LAB SAV TECH SUPPORT et d’amis actifs sur les chaines Youtube, j’ai reprocédé au changement de la céramique et de la thermistance neufs par
de nouvelles pièces également neuves et cette action a résolu le problème.
Il est clair que le code 300-8008 xxxx apparait lorsque la température de buse est mal gérée mais la cause peut avoir de multiples origines.
Commencez par là et avec un peu de chance ça marchera.
Je voudrais ajouter que le bon positionement de la sonde de température ( thermistance ) est important et qu’il faut que le petit trou sur le coté de la buse soit bien propre et avec un peu de graisse thermique avant d’y enfoncer la thermistance.et de recourber les deux fils et de tenir l’ensemble en position avec la bague.

I just got this error for the first time trying to print Fiberon PA612-CF15 at 300 degree nozzle temp on my X1C. It prints other lower temp filaments fine. I saw a solution above regarding lowering the part cooling fan. I did that, and the print finished! Just a small print, but success!

Hi.
Sorry, I know this is a year later, but I’m having the same problem.
I’ve recently gotten the error on one printer, while the other was fine.
I decided to change both hotends. One because of the error, and one because it was worn anyway.
New thermistor, too.
After installing, both printers now have this error.
I’m not quite understanding what you mean with ‘forcing external spoil’ with Orca.
I only use Bambu Studio.
As you said to keep the AMS on with the PTFE tube out of the toolhead, I’m guessing that this would just feed out whilst using the separate filament?
