On the github they write:

USB communication

    Keep the usb connection is ok between the MKS THR36/42 and your Klipper host board, and power on.
    SSH login to your Klipper console and run

    ls /dev/serial/by-id/*

If this should work, is it possible to use a USB Hub to connect the toolboard and the Raspberry Pi to the duet?

Are the mks thr32/thr42 usb toolboards in amy way compatible with a duet2 wifi running Klipper FW?

I have issues to get accurate corners, even if I activate pressure advance (RRF 3.4.0). The first cube is without pressure advance, the second with activated pressure advance. My printer has the classic setup with bowden extruder.

@sonderzug You could have used a hrs df11-10ds connector, like described in the datasheet.

@gnydick Yes, thats also a solution.
But i'd like to do that with the Duet, not by hand.
The Duet has that PS_on Pin which can switch on/off a ATX-Style PSU.
short = psu_on
open = psu_off

The Meanwells RC pins work different.
short = psu off
open = psu on

Thank you for your reply.
But this is not the solution that I've looked for.
I'd like to switch off the printer with the remote control possibility of my Meanwell HRPG-Series PSU.

I've bought a Meanwell HRPG-600-24 which also has the remote possibility.

Is it possible to switch it in the software that it works like this:
rc+ --> rc- short = PSU off
rc+ --> rc- open = PSU on
