Sad and unsatisfied update!

Had 20mins over today so I ran to the shed.
Realized I read the connections wrong for the relays. Reconnected and got the master relay to latch with start button. And disconnect with e stop!

Problem 1. Something is wrong, when I e stop I kill power to 5v psu . This makes my uc300 disconnect from pc and a restart is required for uccnc to connect with uc300 again.
Will look over the wires and reconnect with 5v outside of that loop.

Problem 2. Red fault light is on at all 4 drives.
Guessing it has to do with the enable signal.. since its not over or under voltage (get 50.6v ac at drives they take up to 80v ac or 110v dc) and no holdingtorque so no over/under current. Have tried enable through bob aswell as running ena- straight to gnd.
This could have something to do with my bob aswell? The bob has a green led shining by the 12-24v sign. But a red led right by the 5v pwm text.. is this normal or is it a error?

And another question!
How do I know the port nr to use in uccnc?
Easiest to connect switch and watch in ports and pins whats flashing? :)
