What happened?
The enclosed printers have chamber temperature measurement.
In certain conditions, the chamber temperature is measured as critical. In this case, the printer stops the print and shows a warning message "Chamber temperature critical. Aborting print to prevent printer damage".
Error name: Chamber critical temp
Error code: #31261 (CORE One) #35261 (CORE One L) #36261 (CORE One INDX) #17261 (XL)
How to fix it?
On Prusa CORE One and CORE One L, cool down the chamber by setting the chamber fans' speed to the maximum, from the printer LCD Menu -> Control -> Temperature -> Chamber Fans.
On the standalone and INDX CORE One, open the top lid ventilation holes by sliding the screws on the vents.
