On Wednesday, some Bambu customers woke to search out that their 3D printers had created new undesirable prints in a single day — with none prompts or supervision by customers. Not solely did these prints injury some units once they tried to print a second design atop ones they already printed out however it additionally raised issues about potential hearth dangers. Bambu traced the difficulty again to a cloud server outage — particularly, they despatched additional MQTT instructions once they shouldn’t have and with out checking there wasn’t already a print on the mattress.
For Bambu’s flagship lidar-equipped X1C printer, it’s rolling out a firmware function that can confirm whether or not a printed mannequin has been faraway from the plate earlier than every print. If the printer finds a difficulty, it can ask you for affirmation by a message on the machine’s display in addition to on its Bambu Studio and Bambu Helpful software program.
In the meantime, Bambu’s P1 collection printers, which don’t have a lidar sensor, will present reminders that ask you to wash the plate earlier than beginning a print. You’ll have to verify that the plate is clear earlier than the machine will begin printing. Whereas Bambu will allow each of those verification processes by default, it says you may disable them from the printer’s settings menu.
To handle issues about hearth dangers, Bambu can be introducing a function that continuously screens the temperature of the hotend and warmth mattress. The 3D printer’s display — and its accompanying software program — will show error messages if it detects hotter than regular temperatures. Bambu will begin having printers robotically verify the timestamp of every print request and discard any outdated ones as properly.
Whereas Bambu already pushed an replace to its cloud server with that final function, the opposite firmware fixes aren’t coming simply but, and it doesn’t seem to be Bambu has an estimated timeframe past making them high precedence:
As you may know, to make sure the standard and reliability of software program updates and to additionally be capable of convey you different new options we’re engaged on, we’ll want a while to do all of the adjustments we talked about on this replace.
A few of these updates have been already on our checklist of options to work on, however safety and security issues found moved these options to the highest of our checklist of priorities. Our group will do their greatest to ship these new capabilities within the shortest period of time potential
Regardless of this, Bambu has responded to this difficulty remarkably quick and is working to make it as much as prospects. In simply three days, Bambu has admitted full accountability, investigated, promised repairs, and detailed actual fixes.
The corporate says that anybody who had their machine broken throughout the cloud outage “will obtain help to restore the printers” and in addition dedicated to offering spare elements and spools of filament to make up for any supplies wasted when printers went rogue. It advises impacted customers to contact its assist group and supply logs from the printer.
