Adding a Motor Encoder to your Project!
I found a motor controller on a powermax II stepper motor and decided to try to see how it works. Took some playing around but after finding some wiring bugs it works really well – I made a python script to run through a test of 150 motor movements – with no lost pulses!
This project is neat as it brings together many elements:
- Stepper motor
- Stepper motor driver
- Motor encoder
- Quadrature decoder
- Arduino loaded with GRBL2Arduino
- GRBL/g-code
- Python script to send g-code to the Arduino
- ‘8051 microcontroller (C8051F410 Silicon Labs)
- 7-segment displays to display quadrature decoder counter value
- ‘8051 assembly code
- MCP23017 IO expander Chips
- I2C communication
