make sure that you've told mainsail where to find the MCU.
there's a section in your printer.cfg file where you need to list the serial interface for your MCU 

[mcu]
serial: /dev/serial/by-id/usb-Klipper_stm32g0b1xx_35004A0011504B4633373520-if00

please note that this is my printer config, yours will be different.
on your pi from the ssh terminal, you will need to run 

ls /dev/serial/by-id

then paste your klipper address into the above
