I'm trying to configure a hangprinter with only the A,B and C anchors, so it can move an object across a 2D plane (the floor).

I can't disable the D anchor. Is this a limitation of the configuration tool, or a limitation of the RepRapFirmware?

I'm new here. How can I mark this topic as solved?

@jay_s_uk
Thank you. This config tool is quite comprehensive. is it already stable enough to be mentioned in the documentation?

I'm using the RepRapFirmware Configuration Tool.
After clicking on Custom configuration and next, I can choose these 4 printer geometries:
Cartesian
CoreXY
CoreXZ
Delta

In the documentation I see examples for the following printers:
CoreXY printer
Linear Delta printer
IDEX printer
DLP printer controlled by nanoDLP
Hangprinter
Polar printer
Rotary Delta printer
Serial SCARA printer
Five bar parallel SCARA printer
Robot printer

What can I do to extend the RepRapFirmware Configuration Tool to be able to generate more printer geometries?

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?
