I have a Replicator Mini first gen at work that hasn't been used for at least two years and its been giving me some problems with the filament cooling fan. I updated the firmware and it prints with both the Makerbot Print and Simplify3d. The printer doesn't cool filament when specified in either software although it will turn on randomly when using Makerbot Print. I've checked the fan and its connected internally also works when connected to another supply. Has anyone else had an issue with the cooling fan not turning on when it should?
