@sebkritikel

Currently, i have 12 Stepper Motors (3 x Closed Loop Servo Nema 34 (48V recommended) , 3 x Stepper Nema 17 (24V recommended), 6 x Stepper Nema 11(24V recommended) ) in total to connect for now on my PnP machine project

They mention wanting to add 3x Nema23s as well. Unsure if they would be closed loop.
@developeralgo222 I would recommend posting the part number (and potentially links) to each piece of hardware (motors, etc) you're aiming to use, that way we can best help you.

Motors and Corresponding External Drivers

Closed Loop Motors:

(48V DC recommended for Nema 34 & 36V DC for Nema 23 )

3 x Nema 34 Closed Loop Motor ( 86HSE8N-BC38 ) each with HSS86 Hybrid Servo Driver
2 x Nema 23 Closed Loop Motor ( 57HSE76-2N-D25) each with 2HSS57 Hybrid Servo Driver

Open Loop Motors:

( 24V DC recommended for Nema 11 & 17 )

As per the support info from this forum, i might not need to use the 9 x External drivers for the 9 x Motors directly connected to 3 x 3HC expansion boards

3 x Nema 17 Open Loop Stepper Motor (Benzhi BD4248 ) each with Benzhi Microstep Driver(DM542 driver clone, i think) for driving the 6 heads/Nozzles along the Z-axis
6 x Nema 11 Open Loop Stepper Motor (Benzhi BT12811 ) each with Benzhi Microstep Driver (DM542 driver clone, i think) for the Nozzles/Heads

Duets:

1 x Duet 3 6XD Main Board ( All Closed Loop Motors & Drivers will connect to this 6XD board)
3 x Duet 3 3HC Expansion Boards ( All Open loop Motors will directly connect to 3 x 3HC expansion boards therefore avoiding external drivers and using 3HC in-built Drivers)

Endstops:

Several endstops (20+) for the various Axes as required--- Panasonic PM25U & PM25L
