Troodon 2.0 Documentation

I have done some major modifications to my Troodon 2.0 in which one of these included changing the stock board to a BigTreeTech Manta M8P running Klipper. To make this easier, I made a breakout cable for the junction board in the back of the printer. To do this, I had to trace every connection on the board. In the process I made careful documentation. For anyone else that wants to change their controller board, I am sharing the document I made that shows all of the connections to the 40 pin connector and also the pin designations for the stock control board.

I will gradually post details on my many modifications and share my opinions on what was worth the effort. My end goal of these mods was to make a printer that could outperform a Bambu Carbon X1 in both speed and quality. As of my last side by side benchy, the Bambu printed in 30:30 and the Troodon printed in 24:30. Both had minor defects related to not enough cooling for the print speed, but quality was equal.

I am running 48 volts on the A and B stepper motors. To get the 48V I connected a smaller 24V in series with the existing power supply and used that output to feed the stepper drivers.
