Post by 3DAngel » Mon Sep 23, 2019 2:48 pm

hello to Geetech...

the pdf sch at your site vs the WORKING Marlin 1.1.8 pin_GT2560_v3.h do not match.

need the updated pin out specific to the A20M....LCD

CS_Pin
A0_pin
etc...

Much appreciated
Thanks

here are some of pins... but it is more than what I just marked..
would someone from Geeetech revise the GT2560 V3 for A20M sch.pdf?

pins identification from Geetech's github Marlin for A20M.

it would made thing easier and not that confusing...
thanks

so the pin out is not as described on the schematic.

the pin # are referring to the pin out of the Arduino MEGA board.
received help from Geetech and figured the needed pin out and got the LCD to work on Klipper FW.
cheers
