I built my Pico MMU and I am not using a filamentr sensor, but when I try and switch filament or anything it says I need to clear the hub because the filament sensor is activated. I do not even have a filament sensor wired.

Also, when I do the unload or load command they spin in the wrong direction, how can I fix this?

It sounds like there may be a software issue causing the printer to mistakenly think there is a filament sensor connected. I recommend checking your firmware settings to ensure the filament sensor feature is disabled if you do not have one connected. As for the spinning in the wrong direction during the load/unload commands, this could be a wiring or configuration issue with your Pico MMU. Double-check the motor wiring and review the configuration settings in your slicer or firmware to ensure the motor directions are correctly set.

Just put a ! On your dir_pin to reverse the motor.
