Hi,
Please see the attached:
Release.zip (2.2 MB)
Extract the ZIP file and copy the whole content to the root of a clean sd card. You should then see there
1 The folder ‘TFT35’
2 The file ‘config.ini’ → Please replace this with your own config.ini should you have made changes to it
3 The new firmware ‘BIGTREE_TFT35_V3.0_E3.28.x.bin’
I set the touch plate height to 5mm, please check whether this works by probing via the menue Zero / Z-Probe.
I couldn’t test it as my processor is different… Good luck!
