The temperature of the Heater is configured over CANbus, the Feeding for the filament is done via the STEP/DIR signals to drive the stepper.

In the case of the laser, the STEP pin seems to be used for transmission of the PWM signal, as per Snapmaker2-Controller/Hardware-Link.md at main · Snapmaker/Snapmaker2-Controller · GitHub.
Then canbus is used for “stuff” and the direction and enable pins are used for uart into the camera module.
