If your going to have a feed hold button then you need a Cycle start button to get going again so you'll need an input for that. No point having External feed hold button without cycle Start.!

Also with homing and Slaving then you need to make sure " Home slave with Master" is UN-Ticked in General Config.

Also UN-Tick " Home sw Safety" if your sharing limit & home switches as the switch will be treat as Limit when homing and E-stop the system.

With #3 then you don't need E-stop on it's own Input if wired in series with limits just Set the E-stop Pin to same number as the input your using.! Then when switch is pressed Both Limit and E-stop Led will light in Diagnostics.
