BIGTREETECH-TouchScreenFirmware VS Marlin

I've never seen the 3dwork site before, thanks for that! Look at the settings/config options here and see if they map into that site. Also make sure to check if you need "serial_port_2 1". That was a key for me, everything else was configured correctly but the motherboard wasn't talking to the screen.

When I go here https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware The wirring is gone all of the sudden for some random reason or i am blind

firmware from github

You can't do much to change the menu contents and almost nothing to change the menu structure in config.ini. That's why I wrote you'd have to edit the firmware source files, such as the Menu files under https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/tree/master/TFT/src

Thanks for the ideas. According to the readme, the TFT35 v2.0 only has the RS232 connection, not the EXP connections. It's bolted into my case, I haven't unbolted it yet to visually check for myself. And, according to the readme, the TFT35 v2.0 only supports touchscreen mode, not Marlin mode.

Per this site, to get full functionality you need to:

I've been really happy running looxonline's BIQU B1 firmware. He even has different resolutions for ABL probing, 3X3 4X4 5X5. Plus TFT firmware.

I know some B1 owners also like to use a custom version from Luke Harrison, https://github.com/looxonline/Marlin, which has a few different options and I think is setup to use the BLTouch as the z-end stop as opposed to the official B1 firmware using the limit switch. However I have never used his firmware personally and found the official B1 firmware to be sufficient for my needs.

Are you using the default firmware? My BX was garbage till I used https://github.com/looxonline/Marlin

I'm using the Luke's https://github.com/looxonline/Marlin/tree/BIQUBX_LATEST

Just use the probe for Z homing. It's better that way anyway. You can use this firmware to get started. It's pretty solid. I used the ABL high res version before making my own firmware. https://github.com/looxonline/Marlin

This is a fantastic build for that. It's where i learned a lot of what I know now. Just make sure to change the motherboard definition to the one you have. I think his firmware is still doing the SKR1.4 https://github.com/looxonline/Marlin.git

Hmm i have a biqu b1 with the firmware from luke https://github.com/looxonline/Marlin which seems to have options for kfactor, i used the linear advance test and calibrated my printer, i use prusa slicer and printed 2 xyz cubes before and after and the difference is there, much better
