Chamber fan running full speed right from beginning of print

Avez-vous déjà eu ce “problème”? Est-ce lié à la mise à jour de Bambu Studio?

Hi. I’ve had an X1 Carbon for a few months now and have been very happy about it. However, over the last couple of days, whenever I start a print from Bambu Studio (version 1.9.1.67), the chamber fan starts to run at 100% right away (even though I did not do anything for it to do so!). Trying to deactivate it does not stop it from running; it even reverts to “activated” and 100% on its own. Then it seems things get back to normal as soon as the printer starts extruding. What is strange is that this had never happened before (and I’m using firmware 1.07.00.00).
Have you encountered a similar issue? Is this related to the new version of Bambu Studio?

Same here. It sounds like a jet passing by… after upgrade the fan is too loud.
The x1 carbon printer says firmware 1.07.02.00 is the latest.

But on the website of bambu there is a 01.07.03.00 of april 8 and
01.08.00.00 of May 7 in the firmware history.
My X1 does not show any upgrade message…

Any suggestion`?

In my case, what is strange is that I have not updated anything! At least, not the firmware. The only update the occurred was that of Bambu Studio, and I think I remember seeing the “Network plugin” updating on its own, as well (without asking me if I wanted to download it…which it did in the prior version of Bambu Studio)
