A brand new Tiny G, just hooked up steppers, started tuning the current, stepper was vibrating as opposed to moving at all current levels so I turned down the current and cut the power to the board. Now no matter what G-code command or internal test cycle I try, the stepper drivers (all of them, not just the one channel) won't do anything (not even lighting up the led). The board connects to the computer just fine and settings are set to default.
I have tried everything that I can think of but to no avail. The stepper drivers simply will not step.
