Hello
When I got my A1 last year around Christmas, I was overjoyed.
But right after first test print, I wanted to print something bigger.
Printer started printing no issue at first until it gave me heart attack with big bang and lights in the house went out.
Problem was with heatbed or circuit board, which got sended after contacting support.
After that I am afraid to let A1 print when I am at work or going out like I did when I had Ender 3 without issue.
I know with printer there is still chance that something goes wrong
Do you guys have any experience with something similiar?
I have had nothing but great results with my Bambu Lab printers.
I happily leave them printing unmonitored, this doesnât mean you should assume all will go well, but they can and do run long prints that due to the timeframe means sine sleep will be required.
I often leave them running overnight, it is great to have something finished in the morning.
This often means five printers running in my home running long multi-colour prints.
Recently, many, many frogs for a neighbour.
Prepare.
Make sure your electrics are good to go and you are not overloading the circuits (I am not suggesting that was your problem). With 5 printers myself, I am conscious of this as should others reading this. For example, do not run everything on a single multi-gang trailing socket.
Empty any poop receptacles so they do not fill during a long print.
Make sure you have sufficient filament or failover spare spools on an AMS. You do not want to wake up with a paused print because you ran out.
Make sure nothing can snag the printer in motion or fall on it. Make sure any large heavy prints do not add mass sufficient to âwalkâ off the desk. It can happen, I had this and that meant a lot of monitoring until I could make the surface it sat on less shiny.
It is an electric item you can generally trust, but at the same time it is an electric item.

Thank you very much for answering.
My problem with A1 was that heatbed temperature should have stayed on 100 Celsius, but was still increasing until fuse blew up in the printer.
I discovered what was after I replaced the fuse. Temperature was going up by itself even after starting the printer.
After I fixed it, from there I had no issues, but I lost trust in the printer.
But maybe is time to go over it when you didnât had any issues.
I just hope my house will not burn to the groundâŚ
I didnât wish to assume, which is why I said thisâŚ
Stuff happens; you can only control what is controllable.
Remember this
You do that, and barring anything you cannot control, you will be good.
Try âbaby-steppingâ the idea. Let it run unattended while you can attend and see how you feel. Keep doing this until you are comfortable that it can and has worked well, then trust it overnight.
I have a feeling this is more about you feeling comfortable with your own decisions and confusing what happened with being your fault.
Stuff happens. It is what you do afterwards that makes the difference.

Donât forget that the fuse/thermal overload protector triggered properly to prevent damage to the printer or even your home. This was likely one layer of a multi-layered safety design.
That said, no Bambu printer is fully UL certified and therefore unqualified for use in many institutional, commercial and government applications. Individual sub-assemblies and components such as the power supply may carry UL certification but not the unit as a whole.
If you put the printer on a non-combustible surface like a cement air conditioner pad (very good for machine stability as well) then you further reduce the chance of a failure that leads to catastrophe.
For maximum reasonable safety for unattended printing, install a good smoke detector in the same space and avoid leaving it to run for an extended period with nobody around to hear the smoke detector alarm in the event of a serious problem. Smoke detectors are excellent at picking up just the sort of fire that begins as an electrical fault in a device with significant combustible (think plastic or similar) construction before it becomes a serious hazard to property or life.
I have had several prints over 24 hours and constantly printing stuff over 12 hours. No issues. I leave home. I go to sleep. Me board should be just fine.
Hey there!
Leaving your A1 alone is usually fine, if nobody else is in the house who knows how to operate the printer and it gets a failure, it can get pretty annoying. Usually those problems are uncommon.
I wouldnât suggest using your A1 at night (or any other printer with no enclosure) especially if itâs in your room as the fumes arenât pretty great. If somebody usually is at home, Iâd suggest to show them how to fix the failures like a spool getting stuck.
If you have any other questions, shoot them at me.
Have a good one,
