6.4.x geht ohne Probleme.

Is there an issue with this version reporting THERMAL_PROTECTION:0 in response to an M115 command on a Prusa Mk4. Just upgraded to 6.5.3 and Octoprint warns me that THERMAL_PROTECTION appears to be turned off. 

On 6.5.3 running M115 shows

This has THERMAL_PROTECTION:1 which is right.

Is this a real bug or a bug in reporting or not a bug at all :) ?

Thanks

This is the stable release of firmware 6.5.3 for the Prusa CORE One L, CORE One+, CORE One, MK4S, MK4, MK3.9S, MK3.9, MK3.5S and MK3.5 bringing targeted stability improvements and fixes.

Massively speed up MMU filament changes

A series of improvements have been implemented that massively speed up MMU filament changes by up to 9 seconds. Some changes in the MMU firmware were required as well, so it is necessary to flash a new 3.0.4 firmware to your MMU unit.

The improvements include:

• Parallelized unloading filament from the nozzle and idler engaging.
• The printer does not wait for the final idler disengagement to finish to continue printing.
• Parallelized selector and idler movement.
• FeedingToFinda phase now obeys PulleySlowFeedrate with higher value.
• Optimized idler selection mechanism during filament change.

For more information about MMU improvements and the CORE One L MMU3, check out our blog post.

Updated default input shaper profiles

In 6.5.3-beta, we’ve fixed a bug in the input shaper configuration of our CoreXY printers. If you haven’t changed your input shaper settings, the new values will update automatically.

NOTE: If you have CORE One L or an accelerometer accessory, we recommend re-running your input shaper calibration.
If you modified these values in the past we recommend resetting your input shaper profiles to defaults using the Settings → Input Shaper → Restore Defaults.

Bed LED progress indicator

The CORE One L bed LED indicator now shows the progress of your print, starting from the left and gradually changing from white to blue.

Tuned parking position during purging

The parking position on CORE One and CORE One L has been adjusted so that purged filament flows unobstructed to the bottom, reducing potential debris on the print bed.

Vent grille linked to filament preset

The vent grille now automatically opens or closes based on the target chamber temperature set in the active filament preset. This ensures optimal thermal conditions during printing.

AC supply voltage for the AC controller has been increased

Based on user feedback, we have increased the maximum supported AC supply voltage for the AC controller to 264 V.

Preload all MMU slots at once

The new menu item Filament MMU - Preload All now asks for the filament type only once and applies it to all slots. This is handy when you want to load, for example, five PLA filaments.

Bootloader update

The bootloader has been updated to version 2.6.0. This creates the necessary foundation for the upcoming INDX upgrade.

Fixed input shaper axis assignment on CoreXY printers

The input shaper X and Y axis parameters were swapped on CoreXY printers, meaning the shaper configured for X was actually applied to Y, and vice versa. This also prevented users from disabling input shaping on only one axis. Both issues are now resolved.

Fixed layer shifts during high-speed curved moves

Layer shifts could occur during high-speed printing with curved moves. The motion system has been improved to address the issue.

Note: Please be aware that not all layer shifts have been caused by this issue.
