Hey there!
I thought about upgrading the control board for my MPCNC Primo, because so far I only had an Arduino with a cnc-shield. Said and done, I bought the SKR Pro v1.2 with TMC2209 and the TFT35 E3 V3.0.1 .
There comes my problem, flashing the V1 firmware onto the screen. Because I bought the V3.0.1 and not the V3.0, I cannot just flash the firmware for the V3.0.
I tried many .bin files for other screens, because there is no preconfigured V1 firmware for the V3.0.1 yet. But every time I put the files on the sd-card, inserted it into the screen, flashed the firmware of the screen and put the sd-card back into my computer, there was a .CUR file extension on every file except the .bin file. That means that the board just ignored that file.
Then I saw a post of an user where I saw, that he also used the TFT35 E3 V3.0.1 and I wrote him a message. Long story short, he was able to flash the screen with the firmware from GitHub, which I also tried, unsuccessfully.
I just don’t know what to do, and I would be so happy if anyone could help me.
If you need more information or something like that, just tell me : )
