I'm assembling the Carve King according to the assembly instructions and can't figure out what I've done wrong.
One of the stepper drivers sparked and smoked when I plugged in the power supply- 24V, I verified, to the shield as instructed, not to the board. If you're looking at the shield with the labels "upright", it was the top left driver. I've triple checked everything, all the jumpers are in the correct places, the stepper drivers are oriented correctly, positive and negative wires are where they should be.
Any ideas on what might be have happened?
I installed the spare stepper driver, but I'm scared to plug it in again and blow this one too!
