Hi,

From your nickname I asuume you are Greek like me!

Have you compiled the touchscreen firmware? What you are asking has to do only with the touchscreen firmware and not the mainboard firmware.

[taraxias]

hi. yes i am greek.giannis here..

when you say compiled you mean to add the file ""Copy to SD Card root directory to update"" with BIGTREE_GD_TFT35_V3.0_E3.27.x + TFT35 + config.ini files and with a sd card update the screen or something else that i am not aware off?

[Services8810]

Hi, I am Giannis also.

You have to compile the tft firmware by editing the configuration files like what you did for the mainboard. The files you uploaded are pre-compiled and have specific settings. Your setup (lile mine) is custom and do not match with the precompiled settings

[taraxias]

ok..now i am despert.. i have try it and something i am definitely doing wrong...the bin file i create after the compile, i ender it on the tft screen and it doesnt read it. same thing and when i ender it on the octopus moatherboard cn you please tell me which files i must compile?

[Services8810]

You need to find the master file for the tft firmware. It is a totally different firmware than the mainboard. You need to change the settings at the config file according to your setup and compile the new firmware. Then upload it to the tft

[Services8810]

I will try to find some guidelines to send you...

[Services8810]

Read this...

https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/issues/2754#issuecomment-1476614875

[taraxias]

ok.. i recompile it, i run it and once again it "runs" the other 2 files but doesnt read the bin file i have create after compile

[Services8810]

Tft will not read .cur folders and files. It adds .cur the 1st time it reads them

[taraxias]

i know. i just send you the photo after i "run" them so you can see that it reads the other 2 files and not the bin one

thats thew original files

[Services8810]

The .bin file is the one you compiled?

[taraxias]

yes

[Services8810]

If it does not add .cur I believe it means that it is exactly the same the one in the tft

[Services8810]

Can you share the config file of the tft firmware?

[taraxias]

Configuration.zip

[Services8810]

The config looks ok. If you compiled the firmware and upload it to the tft you should be able to change Nozzles at the extrude screen. By changing from nozzle 0 to 1 to 2 it will push filament from different extruder to the mixing hotend

[taraxias]

thats exactly my problem.. it doesnt changing extruders.. it stacks to 1.. thats what i am trying to solve 5 days now and i cant

[Services8810]

Have you followed these instructions for compiling?

https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/blob/master/README.md#firmware

Under Customization, Firmware click View Full Instructions

[taraxias]

i ll check it tomorrow. to tired atm... thanks anyway..

[Services8810]

Just curious... what hotend are you using?

[Services8810]

Just for info... it is not mixing hotend, meaning it cannot push two or three filaments at the same time. It is switching, so you have to fully retract the one filament before pushing the other

[taraxias]

yea,i know.. i am working to change it with this one atm

[Services8810]

Nice!!! What is the manufacturer of this?

[taraxias]

not been sure because they give it to me,but i thing is this one

https://www.geeetech.com/a10t-a20t-a30t-3-in-1-out-hotend-kit-p-1126.html

o a30t

[taraxias]

i am really ready to smash it.. i made it all right.. i compile it,it changes colors,icons and others setings but no. doesnt want to accept that i have 3 extruders.. i am really despert

[Services8810]

Check that you have set both configuration.h and config.ini with the extruder values

[taraxias]

i am. i set the same values at configuration.h,config.ini and even to config_rrf.ini just in case

[Services8810]

Just for check...when you are compiling does it create a .bin and a .elf file?

[taraxias]

[Services8810]

Can you send a pic of your tft?

[taraxias]

[Services8810]

Are you sure it is a GD version???

[Services8810]

I had the same and used the bigtree_tft35_v3.0_e3.27 firmware

[taraxias]

i have try it before (the bigtree_tft35_v3.0_e3.27) but it doesnt read it at all. i will try it again

[taraxias]

nop..nothing change

[Services8810]

I will try to send you one...

[taraxias]

the thing is that this problem is only at touch screen mode,not at marlin mode

[Services8810]

Send a pic of your extrude page

[taraxias]

what you mean?

[Services8810]

Menu -> move -> extrude if I remember correct

[taraxias]

[Services8810]

Press nozzle once and send pic again

[taraxias]

nothing change

[Services8810]

E0 didn't change to E1?????

[taraxias]

nop

[Services8810]

Very strange...

[taraxias]

dont worry....i will give up..for now... i will use it with marlin mode for now and when i take care of all the other problems that comes up, i will find my way and or that.. i hope.. ty for all

[Services8810]

I am trying to find how to send you a bin file from the comments, from my phone...
