Geeetech

Hello guys I hope someone could maybe help me with setting up the 2208 drivers version 3.0 from bigtreetech I`ve looked all over the place but do not know where to connect the Pdn/UART cables onto the Gt2560 V4.0 Board I got with the Geeetech A-10 printer I`ve tried to contact Geeetech but they just seem to ignore all my questions....

so from my understanding I just have to connect a single cable to the board for each driver I'm planning on using 3 drivers for the x y z axis so 3 cables would need to plug into the gt2560 board but I can`t find any good pinout schematics or just any useful information on where they should be connecting too.

Also i`m using Vert's 2.0 bugfix firmware which works great on the printer with the standard drivers

so before i fuck up my board permanently maby someone can help me in the right direction.

the info I think would be userfull i will put down here:

info about the chip: https://www.arduino.cc/en/Hacking/PinMapping2560

Pdf on the 2208's : https://github.com/bigtreetech/BIGTREETECH-TMC2208-V3.0

Schematic v4.0 dl link : https://www.geeetech.com/download.html?version_id=447

Came to the conclusion The board would not have enough pins that are interupt pins without taking away the lcd and the sd card. and then i still would be short on interupt enabled pins. next to the fact that the info/schematics on the boards are terrible and in fact i came to the conclusion probing the board the schematic is not right on some pins.

so i had to upgrade to the skr 1.4 turbo that im currently using with 2209's and i can tell u the only thing im hearing now is that awefully loud 30mm fan
