Ukrainian Translation

Door Sensor Disabled by Default
The door sensor emergency stop is now disabled by default on new Core ONE units. You can enable it in the settings.
Note: The sensor must remain connected to the xBuddy board to identify the printer model.
Configurable PTFE Tube Length for MMU3
You can now set the PTFE tube length between the extruder and the MMU under Settings → Hardware → MMU.
Ventilation Grille Prompt Timeout
Prompts to open or close the ventilation grilles on Core ONE now automatically dismiss after 60 seconds.
Improved G-Code Chamber Support (#4479, #4484)
Chamber temperature is now included in periodic serial reports and M115 capability info. Thanks to @bkerler and our team for the contribution.
Fixed BSOD when preheating with "Custom" filament
Resolved a BSOD caused by long translated strings when preheating “Custom” filament in some languages.
False “Fan Not Spinning” errors on DIY filtration should be resolved (#4593)
Added signal filtering to reduce false fan errors on DIY filtration setups using MK4 fans with longer cables. This should resolve tachometer signal issues.
Fixed footer not updating after selection (#4345, #4166, #4560)
Fixed a bug where the footer didn’t update correctly after selecting “none.” Thanks to @bkerler for the fix!
Increased max supported nozzle diameter (#4565, #4553)
Nozzle size can now be set up to 1.8 mm. Thanks to @bkerler!
Known Bug
Running a selftest with damaged or unplugged fans shows a “Fan is not spinning” error instead of a failed selftest.
