Ender 3 Printer

Hi there

I just wanted to know if it will work i have an Ender 3 Printer running a Creality 4.2.7 Silent Board will this Firmware work with it as since i added this board to my printer and upgraded the Firmware to the latest creality one it doesn't have the refresh option for the SD Card as i use a SD to Micro SD Adapter and its a pain switching off and on, i know you have a fix for it but wanted to ask before i tried

@john-helyar Is this the E3V2 you changed the main board to V427? Jyers does not work with the old ender 3 screen.
Jyers FW will read the SD card by moving the main menu selection square from PRINT to another selection and back to PRINT.

Thank you for the reply
ok mine is the old Ender 3 i am looking to upgrade my screen to either the V2 version or the Touch screen version, for now i will just stick with switching off and on again

@john-helyar The touchscreen is not supported by Jyers.

I have the Jyers firmware on a 4.2.2 board E3 and a 4.2.7 on a Ender 3 Max with the screen updated to the E3V2 screen. Either board and that screen seem to work just fine.

I noticed this as well - evidently the "clicked-in" state of the SD card is polled in some way and the firmware reports it as a card inserted but not able to be mounted. More of an annoying "fix" potential but when a mountable filesystem is detected the firmware happily mounts to it. This one I might dig into :-)
