Inspired by the Arduino CNC Shield, offers similar functionality.
Requires a Feather-compatible board.
- 4 slots for Pololu stepper motor drivers, 3 axis + 1 clone axis (configurable via jumpers)
- Endstops for X/Y/Z with selectable active level (high or low)
- Pins for external buttons including emergency stop
- Pins for spindle and collant control
- Configurable microstep resolution via jumpers
This is just a quick log to mention that I have finally ordered the PCBs so I can actually test the design :)
Previously I have also verified that it is possible to run the ESP32 port of Grbl on the Adafruit Huzzah32 Feather, which means it should be fairly easy to use that Feather with this FeatherWing. I think it should also be possible to use original AVR Grbl code meant for Arduinos with the AVR Feathers.
I'm interested, why you did it? Many implementations of this device now avalible on aliexpress.
If you want to do good and useful thing add power mosfet (50Vds min) on board for PWM spindle speed control. Don't forget to add diode in parallel with load because spindle BEMF can kill the mosfet. Also, you will need to add an optocoupler between MCU and mosfet.
