Hi everyone!

I'm upgrading an old PrintrBot Plus 3D printer. This is the original PrintrBot and there is no support for this printer anymore. I'm using a BigTreeTech SKR-E3-DIP for the new controller and a BigTreeTech BTT-TFT35-E3-V3.0 for the display.

I have an old Dell server PSU that I would like to use as the power supply for the printer. It's small size will be perfect for mounting to the printers chassis.

Does anyone know how to get this PSU to power on when the 120v power is turned on? I tried just plugging it in, but I only get 2v off of the positive.

Thanks!

I would try searching for the model number in google you will probably find some r/c fourms as they use server psus for battery charging quite often.
You will have to jumper one or more of the small pins to turn it on to get the 12v out.
