Topic: Help Identifying a Vanished 8 pin SMD Voltage Amplifier Chip (I think)

Dear 3D Printing Community,

I bought a XYZprinting da Vinci 1.0 Pro 3-in-1 3D Printer for cheap.
The extruder didn't heat up.

I tested the heating element separately and everything worked so it wasn't the extruder assembly.
Then I opened the back and saw why the heating element wasn't getting 12V.

This is the W5 Motherboard and the next picture is zoomed in to the bottom left.

This is that I found...Yikes! I guess he was removing a short or something but damn.

This is what it supposed to look like... tis is the best picture I could find of the area.

I think this is an 8 pin SMD Voltage Amplifier but I'm not sure.

Can someone with the same board send me an picture of the chip so I can order one and try to get this board working again.


Greetings from the Netherlands

I have no experience or not a lot anyway on board repair in spite f years of electronics experience . That said IMHO that board looks like toast to me. I would not know even where to solder a new chip . My question is what caused that much eat. and what about the condition of the surrounding components. Unless you are highly experienced in board repair I would consider doing a swap to ramps or the like. the other option is finding a replacement check the buy sell trade area as sometimes folks have them to offer.

That damage was caused by a rotary tool .That being said why? There are no longer any pads or connections for that chip which is actually a MOSFET. Even if you did source is there is no way to install it on this board.

Your board is toast and needs to replaced with same or different. There is no way around it.

This damage looks to be intentional.
