RE: Chamber temperature
To add on to this - does anyone know when the HT hotend is meant to release?
I’ve asked Prusa on various media platforms but they never respond.

Here's a quick tip. Until firmware is released that officially overcomes this temperature limit, the HT nozzle won't do you any good, unfortunately.
RE: Chamber temperature
Better late than never, and I apologize for the lack of an update.
It was reported and going over release notes from the firmware, this issue should be resolved.
If not I would suggest people to reach out to customer support (prusa3d.com and lower right corner of the screen is the chat now button, or you can email [email protected]) for assistance.

So the temps were lowered in the last firmware for the core series of printers for safety and was mentioned in the release notes for the firmware

apologies for the long delay in a response, my fault on that one

Im not happy to see my printer having reduced functionality by software changes, so far over the years my prusa printers have always improved over time. Might be that I will have to look into modifying the firmware to get it back to where it was before.

Yes, I can second this feeling, especially as the core one L has the old temp limits with the same electronics.
From the GitHub page - “Lowered chamber safety temperatures [C1]
Chamber fans now start to spin at 60 °C and the printer shows a "chamber overheating" warning, pausing the print at 65 °C.
Please note that the maximum chamber target temperature is unchanged at 55 °C, only safety margins for emergency cooling have been adjusted.”
However, I can report that this doesn’t seem to be correct, as my chamber fans on my core one units are running at 100% when it goes above 55c, so it will never pass 55c to reach 60c
This causes functional print issues as it will introduce a massive cold draft leading to layer shift, warping and other associated cooling issues.
It begs the question - what is different (aside from $$) in the core one L that it can “safely” take 5c greater than the predecessor core one, if they share electronic compenents?
On top of this, which “safety issues” has Prusa become aware of with the core ones printing at 60c?
Lastly, how is the HT nozzle (whenever it ends up releasing) going to function correctly with the essentially 55c hard limit for the chamber?

The HT heatblock has been touted for the CF variants of the high end engineering plastics like: PET-CF, PPA-CF, PPS-CF, PEKK-CF etc. that unless you don't go too big with the parts, don't require a heated chamber. The unfilled variants you definitely do.
RE: Chamber temperature
Sounds like a lot of vaporware sadly.
I am back with another related issue.
I have downgraded from 6.5.3 back to 6.4.0 to retain the 60c chamber functionality.
However, my touchscreen now does not work on either C1+ display.
Is this a known issue? If I upgrade back to 6.5.3 it works, but on 6.4.0 it now no longer works.
Thank you for any help.
