Beeping sound when turning on Octopus Pro 446 while trying to flash it

So im trying to flash my Octopus Pro446 i only have Power for the board and usb c to pi plugged in. as soon as i trun it on the board starts beeping and nothing happens. i set the stepper jumpers to 48v and 24v and i have not connected anything to the stepper terminal power wise. i use a 32gb sd card.

Aha, something is shorting. That beep you hear is the power cutting off, might be from the 5V rail collapsing. Check that you didn't misplace a jumper

but i have nothing connected cant be the jumpers above the steppers right ? so the only other ones are the ones for the fan ports

You don't need to connect something to short it. If you messed up some jumpers or there's metal connecting to points on the back or something, it can short. No there's not really any way to make those short anything And nothing immediately jumps out to me in the video

how is this mounted? I don't see any screws in the mounting holes, and that thing in the picture i marked looks odd

Your wiring sounds like it needs to be redone if you are getting shorts just by connecting a device

I haven't changed anything tho, didn't had shorts yesterday on the octopus v1.1

Like blacksmith said, if connecting power to the toolboard causes a short and prevents the octopus from bootin, you need to go over your wiring.
