oww, but should be possible to disassemple one of the "sameside" extruder and mount it in the opposite side, right?

It seems not enough power supply for the mainboard.You should test the voltage in power supply(normal is 12V) :

Voltage on both connector is 12.20v i assume is okay

You should use multimeter test the voltage of mainboard in here:

Just tested, witouth USB power supply voltage here is just 1.65v

where is the issue?

The holder on Pro W is not same on Pro C, you need a MK8 dual extruder.

as i already have an MK8 Extruder with the Pro W, can i buy this two instead?

dual holder:

Is this also valid for the Pro W?

I think the power supply of pro W is enough so we can use the stock one

and as we already have an extruder can we buy just one more and put it on the holder with the old one?

For the firmware we just need to replace the stock one to the Pro C firmware? No ...

i recently bought a i3 Pro W but from the first run the LCD does not turn on, only the fans start spinning and a green led turn on on the board, the only way to get it working (and to get the printer working) is to connect the USB power (to a PC or a simply USB charger)

here a video of the issue ...
