Thank you. I had a suspicion it might be either a fuse or something related to voltage regulation of some sort, since the Vcc voltage was 5.7V after this happened and that def didn't seem normal.by ugabuga - RAMPS Electronics
Hey all, The setup was working. I have RAMPS 1.6 with A4988 steppers which I will be using for a CNC machine I'm building. (The Root3 CNC) I was trying to set the Vref and my voltmeter probe slipped from the GND pin (I realize now that was a very unsafe way to be measuring the voltage) so it ended up between GND and the next pin which seems to be Vcc. For a fraction of a second there was a bzzzby ugabuga - RAMPS Electronics
