I want to make a CNC panel for my smoothieboard. I will be adding lots of input buttons and indicator lights, and a 4x20 lcd.
So I'd like to know if it was considered to add the the SmoothiePanel:
2-3x CD74HC4067 MUX for 32-48 inputs (buttons, joysticks, sensor switch (doors, tool lenght/broken tool))
Shift registers for 24-32 outputs (5V) (driving 24V relay for indicator lights, buzer, pneumatic relays, water pump…)
Here's a picture of what my panel should look like. (work in progress :)
I'll try to make a tutorial when I'll build it this summer.
Since I have low karma, I can't embed the following image : i62(DOT)tinypic(DOT)com/2kin9g.png
