I have a Rambo 1.4 that I am migrating from a burly setup to a primo setup. I am just wired the Z stepper and thought I would make sure it worked. When I plugged my Rambo into my laptop I received an error of a “power surge”. I have tried just USB and USB + 12V with all the same results. I have also verified the 3 fuses are not popped.
Here is an example image of what I see when I try and plug in this board.
Did this board go poof?
