i thought i had cat 5 cable but it turned out to be shielded 3 pair twisted so used that. the cat 5 cable wil surly turn up now that i have the drives wired. i have yet to wire the fault terminals from the em806 drives to the dedicated estop input which disables the drives once triggered but i can't find any examples on the forum so if any one can shed some light to get the subject......... i also set the micro stepping to 1600, is this o.k.?

1600 MS is fine.

Several ways to use the Fault signal but an easy and safe way is use a Relay with the coils wired in parallel running thru fault signals set Active low and the E-stop running thru a NC contact. This way when any of the drives fault triggers it turns on the relay which opens the NC contact triggering the e-stop.
The E-stop should then kill power to the drives which in turn drops power to the relay allowing E-stop Reset and the drive fault is cleared because power was removed and fault reset on new start up.!

Other way is not very safe as it's relying on control software to stop machine but very easy to wire. It also doesn't clear the fault so you'll need to reset the drives manually. ( For this to work set Input to Active High in Mach3)
