Duet 2 Wifi Expansion board IO usage
I'm using a duet wifi with the signal expansion board. I've got 10 motors to drive and 5 of which are external close loop steppers.
I'm out of IO to control heaters, fans, air scrubber, led's and a couple other things so I'm curious which of the signals say heater 5-7 could be used to control things. Does that ribbon cable make use of all those signals for the external drives or can the cable be rewired to make use of plugged up signal? Or is there another board that somebody's working on to control 6 external drivers? Something like the Duex5 but for external drives?
@jakemestre, we're planning to release a DueX0 board, which will be like a DueX5 but with 5 outputs for external stepper drivers.
In the meantime, heater signals 3 and 4 are used on the expansion breakout board to drive the servo connectors (which I presume you are already using), but heaters 5-7 are unused. So you could tap into them. Another possibility is to connect a SX1509B based expansion board (available form Adafruit and Sparkfun) to the I2C signals.
Where do I sign up to be on that beta?!? In the mean time, do you happen to have a diagram of which wires on the ribbon are which signals?

@dc42 The more I look at the schematics and work with the boards I realize that you're a badass wizard.
