Hello Reprap people, I need your help.
I have a BTT GTR board with TMC2209 drivers and would now like to put a BTT TFT70 into operation. How can I get the TFT to work? Thanks in advance for your help

did you follow the instructions on the wiki first? https://teamgloomy.github.io/gtr_screen.html

Yes, I have, but it doesn't work because he always complains about the Wifi😭

#

you're gonna need to be more specific than "it complains about wifi" 😅

glacial granite Jun 20, 2023, 1:35 PM

#

ok, wifi wants the baud rate, even if i enter it correctly it still doesn't work. It keeps saying "no printer connected and the display beeps unbearably🙈 sorry for my english😁

my tft35 works with :
M575 P1 S2 B57600

#

did you change the baudrate in the screen's settings too?

#

not sure what wifi has to do with your tft

B115200 try and lower it as the wiki says to 57600 ish

#

and change it in the screen settings too

#

I've tried everything🤷‍♂️

#

the last values are from experiment no.100

graceful spade Jun 20, 2023, 1:46 PM

#

a screen doesn't need a high baudrate comm, the lower the better

glacial granite Jun 20, 2023, 1:47 PM

#

ok

graceful spade Jun 20, 2023, 1:47 PM

#

main problem here is BTT TFT screens are unreliable and partially work sometimes when the firmware isn't too broken due to changes in the marlin part of it

#

try updating your screen to their latest version if that's not the case

glacial granite Jun 20, 2023, 1:48 PM

#

ok thanks, i will try tonight👍

#

I'll let you know if it worked

Hey guys, me again. My board is running great so far. I have now connected a BTT TFT70 to the Super 8 Pro and it works so far, except for one small thing. As soon as I press home on the display or something like that, the display freezes or "please wait" appears and then it stays that way. Can you tell me maybe (guess) what it could be?

#

#

could be a lot of things (mainly the screen's firmware being bugged) but you can check that your homing files are not doing things that could "freeze" your TFT when you home, like doing extra includes, etc..

#

does it freeze when you press Home X / Y / Z / All ? that'll help pinpoint what/which file is wrong

I have the firmware from reprap and now I don't know what could be wrong?🤷‍♂️ https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware
