Grbl_Esp32 RAMPS Controller
After building some prototype boards for the really great Grbl_Esp32 by bdring i decided to create my own controller pcb. As i had some cheap RAMPS shields laying around, i made a ESP32 pcb that fits below the RAMPS board and replaces the Arduino Mega. The board runs Grbl_Esp32 and is capable of driving up to 5 steppers - if RC-Servos are used, 6-7 Axis are possible. The board should offer a very cheap solution for smal experimental machines with up to 5 Axis or small robotic applications.
Features:
- Fits below the very cheap RAMPS 3D printer board.
- Up to 5 independent Stepper Axis
- Servo 1-4 (instead of Axis 4/5) mapped to the servo outputs of the RAMPS.
- 3 Outputs - Spindle PWM, Coolant 1/2 - mapped to the FET outputs of the RAMPS.
- 6 Inputs on the input header of the RAMPS.
