Sounds like the darlington pair transistor that controls the fan was shorted. Sometimes they fail closed and the fan runs at full as soon as power is applied.
The question is why? Check for shorts in the cable going from the control board to the hotend especially the connectors.
In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
