NEAT !

I am sure i answered this on the other topic.
But since internet has become a cesspool of bad information, you have every right to doubt me.
Just in case:
-normal metal core transformers can withstand a lot of overload, granted they do not exceed the isolation melting temperature
-stepper drives do not pull 5A from the transformer for a 5A motor, and yes the motor gets 5A easily but the drive might pull a single amp from the transformer. This is an EXAMPLE!!!
-the above depends hugely on the motor and drive voltage
-etc

The cabinet control relay holder with boards. 
the box is just 3d printet and the relay boards are from ali..ex...press for like 2 Euro.

 

Its is exactly the 5ABOB config for the Sainsmart 5 Axis BOB with an added stepgen
on DB25 pins 1 and 14 (removing the PWMgen from pin 1) all other pins are GPIO

Yeah but someone starts a topic mentioning half a nanometre it's going to raise some interest. It's getting around to the level of the CMM NIST has in the US.
Precision is interesting whether it's a machinist hitting tenths on a manual lathe, a grader operator nailing a sub roadbed to the millimetre, the construction of the bridge over the harbour in the capital of my state or the work of Brunel in the 1800s.

Could StepGen be used to convert the absolute position data from the Fanuc encoder channels to quadrature pulses for outputting to encoder input on the drives? 

Cincinnati sabre 500. A simple 3 axis machine. The tool changer pivots on two hinges to swing the carousel under the spindle. It's resembles an arm bring a glass to a mouth.

Hi,
Thanks for your file. Please confirm if it contains the input pins information for 5 Axis BOB.
If not, please add the same.

If the resolvers connect to the drives (expected with AC servos) ,
a 7I49 is not needed (or useful)

Yes, assuming:

Black is out
Blue is ground = 24V common
Brown is +24V
