New Mainboard 4.2.7 beeps
Installed a new mainboard 4.2.7 on my ender 5 pro. As soon I try to install the firmware it starts beeping.
I downloaded it from the creality website, don't have a BLtouch, so I chose "original version".
Checked everything twice, gave them an extra push, X Y Z and all are on the right position.
What did I do wrong?
