Hello, 

It seems that the pin for TIM1_CH3N  should be PE12 as per schematic but CubeMX shows it as PB0. Please correct it and let me know how to fix it at my end for time being.

If you want to use PE12 as TIM1_CH3N, click the PE12 pin and select the TIM1_CH3N function.

There are several pins to choose from. CubeMX picks the first one available. PB1 is a valid pin for this function as well.
