Summary

• Fixed nozzle temperature swings and thermal runaway errors [MINI/+]
• Fan Test no longer fails on a print fan spinning faster than 7000 RPM [XL/+]

This is the stable release of firmware 8.0.1 for the Prusa XL+, XL, MINI+ and MINI, bringing two targeted fixes. Firmware 8.0.1 follows firmware 8.0.0; for a complete overview of the features introduced in 8.0.0, users can refer to its release notes.

Fixed nozzle temperature swings and thermal runaway errors [MINI/+]

Since firmware 7.0.0, the MINI could drive the nozzle heater at full power during retractions, so the nozzle temperature swung around the target and a thermal runaway error could stop the print. The heater power is now reduced during retractions as intended.

Fan Test no longer fails on a print fan spinning faster than 7000 RPM [XL/+]

The Fan Test in Control - Calibrations & Tests accepted print fan speeds of up to 7000 RPM. Depending on the version of the fan shroud, a healthy print fan can exceed this value, so the test failed and kept the tests that depend on it, such as the heater tests, from running. The upper limit is now 8000 RPM.
