The SourceRabbit 4-Axis CNC Motherboard is a “small computer” that links a personal computer (desktop or laptop) with motor drivers supporting step/direction control. It is compatible with most motor drivers on the marker and can produce up to 120.000 steps per second.
The SourceRabbit 4-Axis CNC Motherboard hosts an ESP32-DevKitC-32D made by Espressif Systems preloaded with the latest 32-bit version of the GRBL firmware. The ESP32-DevKitC-32D has a dual core processor at 240Mhz, 520Kb ram and uses the USB port, available on all modern computers to receive and send data. The ESP32-DevKitC-32D also features bluetooth connectivity but you need to change the firmware in order to use that. We strongly recommend to let the firmware as is and use the USB port to communicate with the board from your computer.
Although SourceRabbit 4-Axis CNC Motherboard is compatible with many GRBL GCode Senders, we suggest you use Focus - PC Based CNC Control System to control you CNC machine.
