Topic: 3 Axis CNC Controller (Read 2900 times) previous topic - next topic


I've made a cnc controller based on an Arduino UNO for my cnc mill:


  • Its not strictly an Arduino project - I've used AVR Studio 6 Assembler / VB.NET but its free, open source and uses an Arduino UNO so you might like it nevertheless...

  • Uses a wireless Logitech gamepad to manually control the machine from a few steps per second up to full speed.

  • Controls the VFD of a spindle motor with just 2 resistors, 1 capacitor and 1 optocoupler...

  • Quite fast... >>70000 steps per second...

  • Some built in commands for drilling, circles, rectangles etc. with macro editor - quite nice for simple tasks that may be done without CAM program...

Wow, that's a lot of assembler!
[ I won't respond to messages, use the forum please ]


the assembler program isn't very large or complicated - its less than 1kb (roughly 2.5% of the Arduinos flash memory).
The rest is just used for 2 ramp look up tables...
