Description
The Geeetech GT2560 v3 board is prepared for 3 extruders. Normally only 2 extruders are populated with connectors and stepper drivers (for A20M), however the 3rd extruder (E2) would work as well. The only thing you need is an additional stepper motor and a connector.
This patch configures the pins for E2 thermistor and heater.
As well as setting SPEAKER as the default configuration for A20 boards.
Benefits
Enables 3rd extruder for GT2560 v3 boards.
