Note that you probably never had to upgrade to Marlin 2.0, you could have inserted a pause or at least a dwell command in your older firmware.

I tried this https://3dprinting.stackexchange.com/questions/14191/cant-manage-to-force-my-print-to-standby-while-i-insert-a-nut-prusa-slicer-an , what is a dwell command please? Also I needed to modify the nozzle to prober offset because the stock fan duct was bumping into the prints and idk if it's feasible on chitu boards

Tried this https://www.tronxyonline.com/Firmware-XY-Series-a63177.html but after launching the gcode print and restarting, Marlin persists...

what did you do to actually get to the problem in the first place?

I'm not sure to remember but I think I miss-pressed `store settings` in the `motion>bed-leveling` touchscreen UI

(Asked by: username_0 on 2020-08-17)

Because I needed to insert nuts in my prints and therefore G-code instructions in their file, I upgraded my printer firmware to Marlin as in here :

At the beginning I did used to get the 6 beeps when booting, and was able to boot back to the initial firmware when hiding the `upgrade.cbd` file in a folder, instead of the root level of the SD card.

But I did by mistake load/save some settings to the EEPROM I guess, and I cannot get back to the initial firmware - at boot time there isn't any beep anymore and it boots directly on the marlin boot wallpaper.

How to prevent Marlin forcing the 3D printer to boot on it please?
