Duet expansion breakout board not helping me

[dc42]

@Pritt said in Duet expansion breakout board not helping me:

If I use 5 external motors that need the 5V differential signal, do I connect the PUl +, DIR + and ENA + of the 5 motors to the 5V of one of the heaters?
That is, the 3 positive pins of each motor x 5 motors, do I connect the 15 to the 5V of one of the heaters?

Stepper drivers for large motors do not need 5V differential signals. Most need 5V single-ended signals. A few need differential RS422 signals, sometimes described as "5V differential" but in reality about 3V. The expansion breakout board can drive either type, depending on how you connect the drivers.

Stepper drivers designed to be used only with PLCs typically need single-ended 24V signals.

I think it is a very interesting topic, and, from what I have searched, in no thread has a good final result been reached.
For that reason, I open a new post, to see if with your help I can come to fruition.
