Vivedino Troodon rebuild

Hello! I am posting here after reading about various people trying to get Formbot/Vivedino Troodon machines working properly with the existing electronics.
I have one of these machines which is up and running with a new custom built printhead, but the lack of futureproofing means replacing the electronics.
Please could someone share some knowledge to help me order the boards and parts needed to refit one of these machines? I looked at https://duet3d.dozuki.com/Wiki/Going_from_Marlin_on_Arduino_to_RepRapFirmware_on_Duet#Section_What_electrical_details_are_needed_to_configure_RepRapFirmware already, but would be very grateful if someone who has already gone down this path could help!
I am looking at getting a Duet 3 mainboard as a base.
Thanks in advance, best regards, Mike
@mikento what motors and how many does the Troodon have?
@mikento thanks for the message, I guess linking to the board caused the form to reject your reply!:
It has 6, 1.8deg steppers (42mm) for the axes and 1 0.9deg stepper for the extruder. X, Y, Z in the config are configured at 1200mAh, 24v and the extruder is at 650mAh, 24v.
The board I am replacing is this https://www.formbot3d.com/products/troodon-mother-board-and-touch-screen.
The most economical option would be a Duet 3 mini 5+ and a mini 2+ expansion board. That provides enough current for those motors and provides 7 stepper motor outputs (which is what the setup needs)
also what happened to formbot that they are selling those boards off for $10?

@t3p3tony that's just a driver. The boards are $80

Thanks for the help! I will get some boards and bits and pieces ordered up!
My mistake about the board - thought that was really cheap : )

@mikento I have a Troodon 400, I have actually rebuilt most of it with a Duet 3 6HC and a Tool Board v1.1 but clearly a Duet 3 mini 5+ and a mini 2+ expansion board would be the best.
Considering you are looking to have a custom print head, I would like to suggest looking at the Tool Board, it will simplify a lot the wiring and also opens the possibility to use the accelerometer (there are currently basic functionality implemented with RRF3.3 but more will come with 3.4).
Formbot's custom board are not working on the newer version of RRF, I think the last that worked was 3.1.
I'm not sure if the screen from the Troodon will work on a Duet 3 board, it was connected using the ribbon cable.
Can the 5v, GND, Rx and Tx be used with a 4 wire cable?
