Solved Can I have more than 10 motor controllers?

[appjaws]

I have a core XYUV machine with a 3 colour diamond hotend. I use 3 motors for the Z operation and use the excellent automatic bed levelling system, which keeps my motors from drifting on power down and start up.
I want to start using a 5 colour diamond hotend so I need 2 extra motor circuits,
Any suggestions on extra hardware and setup instructions to achieve this?

You can connect 2 external drivers to the CONN_SD connector. See https://duet3d.com/wiki/Using_external_stepper_motor_drivers.
