Hi all, hope everyone is well. I have just started wiring my D Bot and would like a bit of guidence if possible. I may decide to run 3 Z axis stepper motors so I can use a BL touch probe. Is the expansion board I need the Duex or is there a dedicated expansion board for the Maestro? Now to endstops, I have wired the limit switches in normally closed mode, is this correct for the default firmware setting? In the unactivated state, I get a YES to endstop triggered, when I press the switch, the reading changes to NO, is this correct? I also want to run two case cooling fans, one blowing and one exhausting, what is the best line of attack? Wire both to one connector, with + and - reversed for one to make it run in reverse or connect to the 24V in from the PSU? I am using 24V fans.

You should invert endstop signals to make it work correctly, so use right S parameter on M574 command, assuming you using series 2 firmware, not 3.
And never connect fans with reversed polarity. If you want them to work as blow and other to suck, just mount them with dirrerent side to case.
Here is the Maestro stepper expansion board.
