This is a Manual controller for CNC milling machine, SRM-20.
SRM-20 is a product of Roland D.G. and It have a slot for inserting Arduino UNO.
We made a prototyping of Manual controller.
Step 1: Rotary Encoder
First, we prepared some parts. Most important parts are "Rotary Encoder".
It's detect the rotation of dial wheel and the direction.
We picked out 3 rotary encoders for each axis, X, Y, Z from 3 piece of PC-mouse.
Step 2: Making Enclosure and Dial Wheel.
We made dial wheel and enclosure by CNC milling.
First, we formed the 3d-model of them by using sketch up.
Step 3: Connect to SRM-20 Main Board
It is connected to SRM-20 by using Arduino UNO Digital input pins.
Finally we developed the program on Arduino IDE.
It can move by rotating each wheel.
