Optical encoders with DC motors

In mini 3 axis you can connect all
3 motor enable signals together.= -2 outputs.
3 home switches together when homing one axis after another. = - 2 inputs.

And here is a video of my implementation.
Two axes in closed loop with a single chip and a PC. Amazing!

What do you mean "mini".
Enable signals are usually needed for PWM control. I don't think we can connect them together.
If we put the home switches in series (if I understood correctly your idea) then until the last axis is homed there will be force on the rest axes, something not good!

3axis is a small machine (xyz). Up to 9 are possible.

If you want to stay on position, your motors must stay under power as long as you want to do something soon = enable on. All my drivers (3 machines) are always connected to the same output. ( Enable, step, dir).

Lcnc is easy to setup having several home switches in series or parralel to make sequential homing. Well documented in the html...

Hi Mike, I don't understand what you mean?
How can you connect Enable, step, dir of all drivers together?

Nop..naturaly not in that way!

Connect all 3 driver-enable signals together.

Plus 3 times the two signals for each motor.
Naturally each motor needs his own step and his own dir.

In sum you control the three motors with 7 output signals..
