Description

This is a simple 3 axis CNC controller for FluidNC. It has the following features.

 

  1.  Built in and programmed ESP32 module $ Meg Flash, Wifi, Bluetooth.
  2. USB C interface. 
  3. Micro SD card socket.
  4. (3) TMC2209 stepper drivers in UART. They are fully configurable in firmware for motor current, microstepping, etc.
  5. (4) inputs for limit switches, control switches, etc
  6. (2) Stallguard detection via separate inputs. The third motor can use stallguard with a solder jumper.
  7. (4) 5V digital outputs. These can be used for spindles, laser and accessories.
  8. 12-24V voltage input.
  9. All connections via terminal blocks. No connector crimping required.
