RE: 6.5.3-RC Firmware for Prusa CORE One(+)
Well, i guess that there are "things" inside which are not happy with temperatures above 60 degrees... entire printer must be built from the start with high inside temperatures in mind. C1 obviousliy isn't...
Agree. But I believe this new. I don't recall seeing the prior.

And you may well have gotten that 1 Hz difference running back to back with the beta version too.. I did.
RE: 6.5.3-RC Firmware for Prusa CORE One(+)
After updating to firmware 6.5.3-RC, OctoPrint displayed the critical warning message "Firmware unsafe".
After consulting with the OctoPrint developer, it turned out that "Thermal protection" was DISABLED in the RC firmware:
THERMAL_PROTECTION:0
An issue has been created on GitHub.
Hope the devs fix this quickly.
RE: 6.5.3-RC Firmware for Prusa CORE One(+)
Printed a large rectangular tray last night, the largest thing I've ever printed, and the wall quality was really excellent with RC version and the accelerometer tune-up. No artifacts of significance, save for a "hull line" that's to be expected. No visible VFAs at all.
Hope the thermal protection issue is addressed quickly!

So I jumped around and confirmed a few things.
1). Thermal protection has not, nor ever will be switched off by us, safety has always been a priority for us.
Yes I know I sound defensive, but I want to make that absolutely clear 🙂
There is already a github ticket submitted for this a few days ago.
https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/5164
This is not a Prusa issue as far as we switched off anything 🙂
The Chamber thermal protection isn't defined, m115 is reporting it as disabled. We can define the chamber temperature, but since we do not have a chamber heater, this is causing a odd situation where m115 reports inadequate thermal protection.
So that is it in a small nutshell, you can use the github ticket to add your situation to the case and follow along, but I just wanted to clarify the situation before anyone jumps the gun.

It may not have been intentional but as a professional developer, I know how regressions can creep in under edge cases that were never covered by unit or integration tests. Later I might run a diff of the 6.5.3-RC and 6.4.0 source trees and see what else may have changed. There does seem to be a difference in some thermal protection logic.
