See ExcessShiv. Looks like I’m wrong about it being possible while not printing.
Comment on Did Bambu Lab change something on the A1 recently?
akilou@sh.itjust.works 3 weeks agoWhat’s the defect? Can you send an article or something? Is there a recall or something I should do? In what way do I “be careful”?

Make sure your printer is not on something flammable, have a smoke detector (are common practises for safety). Since the problem is about power draw, and heated bed is what needs the most i got a cool build plate so i’m now printing at 30°c instead or 60°c. Obviously, some could also replace the cheap component bambou has put in but i’m not confident enough with my electric skills.
About the issue, i recall that quite a few A1 got on fire. Bambu denied there was an issue and said it was a user fault. Some guys pointed out a weak component that would just barely support the maximum load printer can use and ranked it as unsafe. No recalls as no issues for Bambu

As I know from reading various outside sources and have heard, there have been NO actual fires reported and verified caused by the NTC failure in question. Just some scorch marks and a bit of localized melting.
This does not mean that a fire is impossible, but that you would need to have an exceptionally bad day for the fire resistant plastic of the housing and board to catch fire.

Is there any documentation about the fires? How did you find out about them?
paf@jlai.lu 3 weeks ago
Various report of users and a video that explained the issue. Don’t have sources now, it has been a few months

I’m currently building an enclosure for mine that is double layered with backer board (concrete) and drywall (high inflammability).
also adding in a smoke detector that can cut off the power with a backup thermistor that when triggered will cut off the power and set off an even louder alarm.
my hope is to have it sealed air tight enough that even if a fire were to start, it would quickly run out of oxygen to burn. I may lose the printer, but hopefully I won’t lose my house.
my preference would have been to keep my printing to an exterior building but that’s not possible right now.
I share this in hopes someone might get some inspiration and protect themselves from the inevitable fire that starts from the hobby.

Be careful if you seal it completely, electronics won’t be able to cool down properly, it needs some fresh air.

thanks for the input. I’m going to be moving the controller outside the enclosure but there’s still the motors and hot end to contend with.
I suppose I could monitor interior temps and activate the venting/filter when it reaches temp. would be tricky though, because then I would risk feeding a fire and allowing it to escape should one start.
