For the E3 V3.0.1 I guess you will need a different firmware file. This should be the file BIGTREE_GD_TFT35_V3.0_E3.* which is not included in the repo you referred to. To be sure you can check what is printed on your TFT processor. If it starts with a GD then you will be sure.
Best is to use the V1 firmware. Ryan has just released a new version today.
it has the stock menu and setting
and yes is GD processor
in the las config
i had the spindel control
do i have to do a new config with the old setting ?
That’s ok, this is as expected. This also means that you’ve successfully flashed your TFT. If you look at your SD card again, just to be sure that the flash process was successful, the file extensions should have changed to ‘*.cur’.
yes is GD processor
Good. That is exactly what happened to me. I can’t remember how often I had tried to flash the firmware until I realised that the GD processor needed a different file.
in the las config i had the spindel control
It may well be that ercoleg (the owner of your old firmware repo) changed the menu structure. If you’d like to get exactly this look and feel again, the only way is to ask them to update their firmware for the GD processor.
do i have to do a new config with the old setting ?
Difficult to say. The config file will have changed in the last 3 years. But from what I understand so far the menu structure cannot be changed via the config file. You may want to try the Marlin mode instead and see whether this suits you better.
