I printed the original one not realising that the printer wouldn't detect when I would swap SD cards so I would need to power down the printer then power back up to be able to read the new SD card.

I designed a push button to ''remove TF'' then ''insert TF'' so that I don't need to restart my printer every time.

I heard with a custom firmware the new SD would be detected but I can't compile a firmware and don't want to mess up my printer.

if you are in the same situation as me... enjoy !

Also, ignore the commentary in the video, I was sending it to my friend.
