LCD/board pins for A10T with GT2560 V4.1

[the3dprintingbelgian]

Hello,

I just got a new A10T running the GT2560 V4.1 board. I noticed it is running a SUPER ancient marlin 1.1.8.

Obviously I want to update the firmware to a modern marlin that has massive improvements to mixing support.

I have used marlin's A10T config and advconfig and tried vert's fork. nothing.

The printer connects to pronter face and I am able to control it. heating works. but the LCD does not function. blank screen.

I request for the correct pins so I can modify the GT2560V3.H board pinout. Geeetech is using marlin for their printers so you have to release source. so please give us the board pin out of the 4.1. don't close source something while profiting off open source.

Also every single extruder extrudes the wrong amount. E0 extrudes 5 mm less than the requested 100mm. E1 15mm less. E2 9mm. I cant change the esteps separately if you are going to keep your stupid "we are breaking GPL rules and keeping the 4.1 closed" thing can you ATLEAST update the firmware to have distinct E factors turned on.

heres a pin file for the GT2560V4

https://pastebin.com/T7Xw0pxh

these pins are from the official github repo, that work on 1.1.8 and im currently building my own 2.0.x version and they seem to be working
remember to add

#elif MB(GT2560_V4)
#include "mega/pins_GT2560_V4.h" // ATmega2560 env:mega2560

to pins.h and

#define BOARD_GT2560_V4 76 // Geeetech GT2560 V4.0

to boards.h

So what LCD do you have defined? managed to get the board setup in my boards list. some non-fatal errors. just need to know what the correct LCD is.

Bumping this. there has to be somebody here tech savvy enough to be able to port the functions of the LCD to marlin 2.0

You know what. I am raising a 30 dollar bounty for anyvody who can get a modern build of marlin working with the A10T with the V4.1 and the YHCB2004 screen.

Hi.
JFYI. Should work again with Verts Marlin (v2.0.8) version now. Just uncomment the //#define YHCB2004 line and compile it.

Regards,
Chris.
