I got my reply to my open ticket on this topic. Note that I stated the whole purpose to restoring back to 1.03 is because that revision demonstrated the most stable LAN-only connection, 1.04 and 1.05 have numerous reports here by me and others as having become unstable in LAN-only mode.
I am not suggesting that customer support be open ended, but withdrawing support on something already released is an egregious and aggressive move against the customer and what’s more, it costs Bambu NOTHING. This is the cheapest form of increasing customer satisfaction there is, just leave it alone. But when you work against the customer, they have a right to be angry about these practices.
Bonjour,j’ai trouvé comment faire tu lances ta mise à jour depuis ta machine, la mise à jour terminée on va peut être te demander de faire la calibration. Tu ne la fais pas mais à ce moment sur ta machine tu fais Une réinitialisation usine (toujours depuis l’ écran machine). Et ensuite tu effectues la calibration totale .
PS : Moi aussi j’avait des soucis après la mise a jour fait comme je te dis et se sera ok.
No, Restoring factory settings does NOT change the firmware version or change the versions available for rollback.
After a firmware change, “Restore factory settings” does often correct errors and unexpected behaviors by a device. With my X1C, I no longer even attempt to use the printer after an update until I’ve done the Restore.
My theory (which I have not attempted to prove) is the new firmware may have caused certain fixed data storage locations to shift, so that when referenced, the values are invalid. “Restore” then initializes those locations. That theory may be nonsense, but for whatever reason, I’ve not had a problem with any firmware version after a Restore.
Unfortunately, filament calibrations stored on the printer by Studio will also be erased by a Restore. I avoid that problem with OrcaSlicer, which stores that information in the User preset.
Sorry but your personal experience is limited and you are obviously unaware of firmware problems in the various printers that HAVE BEEN ADDRESSED by a follow up update.
The most recent example would be a P1 update that broke flow calibrations. The list of people reporting the exact same problem was long and numerous. Submitting a ticket to tech support would get the response “We are aware of the problem and working on a fix”. And guess what? They came out with another update to fix the problem.
There is now a problem with the A1 firmware causing the nozzle to drag over the infill on taller objects with small layer heights that didn’t exist before the update. Again, the list of people posting this is long.
So don’t assume that just because you haven’t experienced this that people are just complaining.
Unfortunately these bug issues is direct evidence of the lack of software engineering and design discipline. You cannot program your way out of this issue. Like hardware, any software changes require COMPLETE testing which require engineering from day one. What we have here is “Wack-a Mole”. Then one thing is “fixed” it breaks something else.
Bambu Labs is not alone. Even Apple and Microsoft have this issue. I believe they know they have problems but they do not understand what is needed or what to invest in. And yes, this is a fact, not my opinion.
The ratio of software engineers to programmers is at least 10,000 to 1.
When you use open source you are placing a bet it will work. Open source is not engineered, its programmed until the green light goes on. Engineering and programming are not the same, full stop.
The reality is, they sell product despite all of the buggy code, and since there is no better alternative at this price point, they will continue to sell products. Welcome to supply and demand.
