Using a duet3 to drive an incomplete hangprinter (only 2d)

[genialePrutser]

I am looking for a way to position a sensor on the floor, so it can measure the light pattern from lights above.

I'm planning to build a system with 4 cable winches in the corners, and then connect those with cables to a platform in the middle containing the sensor, like this:

I only need 2d movements, so I'm planning to put the winches in the lower corners of the room, instead of raised like in the picture above.

In the documentation I found a configuration example for a hangprinter. https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_Hangprinter This example uses 3 winches in a horizontal plane, and a vertical one:

Can this example be modified to use 4 winches in a horizontal plane?

How can I configure a duet3 to drive the 4 winches in the lower corners of a room?

@genialePrutser If you are driving the hangprinter using a 6XD, you may get away with just leaving the D anchor motor disconnected. The main dev of the hangprinter kinematics thinks this would work. If you are using a 6HC or Mini5+, you may need to hook up a dummy motor for the extra D anchor to avoid "phase disconnected" warnings/errors.

PS: If you set the motor current for the D drive to less than 500mA, you should not get any "phase disconnected" warnings even if you leave it disconnected.
