I recently bought a CR-Touch and installed it. It is already recognized by the Printer (the pin moves out 2 times on boot). I wanted to update the firmware to use it for my prints. I followed guides telling me to download the firmware (from CR Touch 3D Printer Parts - Creality 3D and choosing the “Ender-5 Pro CR Touch Firmware” and using the V4.2.2 board version, as it is my board.
Unfortunately, formatting the SD card with FAT(32) and 4096 Bytes, saving the firmware on there and inserting into the printer does not work. The printer boots up normally.
Can you tell me why the printer is not installing the firmware? What mistakes am I making?
My current Marlin version is 0.0.8, which it shipped with. Is that the problem?
The only file you should be placing on the SD card is usually the .bin file. If the file is not being read by the printer then you can also try renaming the firmware file to something like firmware.bin as that sometimes helps.
