Toolhead PCB Change

Sovol SV06 ACE
1

Hey folks,
last week i fried my ACEs Toolhead PCB. Today i got my replacement part, put it in, started a new calibraton and nothing happends.
After a few minutes an error message appears.
‘extra_mcu’ unable to connect.
On the PCB the blue light is on always.
Does the new PCB needs software? But how?
I’ve already opened a ticket at Sovol but after one week waiting for parts to arrive i’m unpatiecend and want to Print :smiley:
TIA guys

Felix

Update:
Firmware flashed und updated back up to V19. Besides language, I changed nothing but still have the same issues.

Hi,
Are you sure about the wiring of the motherboard?

Maybe I wasn’t precise enough.
I replaced my old PCB with a brand new one ordered from Sovol.
I’m not sure if I maybe fried the wiring too. But webcam, LED, HotEnd Fan and Blue LED on the PCB are working
