Original Prusa XL Enclosure functions (XL)

The XL Enclosure is designed to be seamlessly integrated with the rest of the printer. Not just the physical parts, but also the software, a new menu becomes available on the LCD touchscreen called Enclosure. Because the Enclosure is directly connected to the mainboard of the printer, you can configure a number of useful features. You can set up the filtration performance and even post-print filtration duration (e.g. when you print from materials such as ASA or PCCF) so that the system runs for additional time to filter out all particles produced during the print job. For more information, read this article.

Enabling the XL Enclosure in the menu
You can enable the XL Enclosure by going to Control -> Enclosure (Enable) on the printer. Then, run a fan connection test to verify that everything works. After that, you will see the Enclosure menu.

Features

Filtration When you have enabled Enclosure and Print Filtration, the fan will operate at 80% of RPM. You can adjust the filtration performance in the menu (from 50% to 100%) during a running print job.
Post Print Filtration You can also enable Post Print Filtration in Control -> Enclosure -> Manual Settings -> Post Print Filtration. When certain filaments (ASA, ABS, PC, FLEX, HIPS, PP) are detected in the G-code, the filtration will run for an additional 10 minutes to filter out all particles produced during printing. You can adjust the Post Print Filtration setting from 1 to 10 minutes..
Note: PLA/PETG prints do not require post-print filtration.
MCU Cooling The MCU checks the temperatures of the electronic boards on the Original Prusa XL.
MCU Cooling has the highest priority and activates automatically (fan at 100%) when the enclosure is powered on. MCU cooling is activated when temperatures of any electronic board exceed 80°C and stops cooling at 75°C, regardless of whether printing is in progress. This is to protect internal electronics from overheating and to extend their lifespan.

Temperature Display You can display the temperature inside the enclosure in the footer by going to Settings -> User Interface -> Footer. The temperature value is derived from the current or first tool board temperature. The temperature will be displayed 5 minutes after the start of printing. This delay is due to the need for temperature stabilization inside the XL Enclosure. The temperature will reset to “–” after the print is complete.
Filter Expiration Tracking The enclosure tracks the active filtration time (not print time). After 500 hours, a dialog alerts the user that the filter will expire in 100 hours (the estimated lifespan is 600 hours of runtime). The dialog will let you choose from [IGNORE] - which will remind you before every print to change the HEPA filter, [POSTPONE] - which will postpone the dialog for 5 days, and [DONE] - which means that the HEPA filter has been changed and will restart the filter counter. After 600 hours, a dialog suggests changing the filter with a link to prusa.io/xl-filtration.
Fan Error Check will alert the user to check the fan connection and cleanliness if the fan isn't spinning as it should.
Fan Connection Test will check if the fan is properly connected. This test runs whether you enable the enclosure from the menu or start the print.
