Vivedino Troodon Control Board question
Never rush things right? Sigh... Well I rushed things and mixed up the wires going to a new extruder I was installing on a troodon. When I turned it on after installing the extruder, it did not turn on. I'm only getting the blue vin light on the control board.
I tried replacing the fuses, nothing changed. And I've moved on to looking for damage on the board. The only thing I can find is this one chip looked burnt/melted, I cleaned it off with alcohol to read the numbers but I cannot seem to find it through google.
The numbers I can read are:
Does anyone know what this is & do you think replacing it might fix the issue? I'm gonna order another board but with global shipping in the toilet... I was kinda hoping to try some fixes in the mean time.
@warbunnies have you tried contacting formbot for a replacement or any warranty support?
I'm definitely going through the process of getting a new board from them BUT the main issue there is international shipping, there are crazy delays right now. I'm asking if they can do any sorta overnight shipping but my guess it that it will probably take a while and running the prototyping shop on one printer is going to be rough.
@warbunnies looks like the A4403 voltage regulator chip to me.
@dc42 Thanks! I'll read more into that but it certainly does look like it. Would explain why the low voltage is getting no power.
