Hi Guys, I'm new to Arduino and as usual with any project, I throw my self in at the deep end!!
What I am aiming to achieve is to control 3 stepper motors independently without using GRBL. Motor 1 will move the saw fence, motor 2 will lift the saw blade and motor 3 will shift the angle of the blade.
Components:
1, Arduino Nano R3
2. 3x Nema 17 Stepper Motors
3. 3x A4988 Stepper Drivers
4, I2C 16x2 / 20x4 or Nokia 5110 LCD's
5. 4x4 Keypad
6. Breadboard, wires, etc
7. 3x End stops / Homing switches (Maybe 6 for the end limits if they will fit on the nano.)
How I plan on doing it is, At switch on all motors will move to their home position. Then by pressing A on the keypad, it will allow the control of motor 1 and display on the LCD "Current Position" and "Enter Distance" and when I press B it will control motor 2 and C motor 3. Each motor will have a limit in MM from the home position so they don't exceed their own limits.(if I can't fit anymore limit switches on the nano)
The motors and drivers will have their own 12/24V power supply, and all the other components and Arduino Nano R3 will be mounted/connected to a custom PCB.
Here is a link to the brainy bits video where he is controlling 1 stepper motor just like how I want to do it with the saw fence but with a ball screw instead of a belt.
If anyone can help me with this I would be most appreciated.
Thanks,
Mike.
