I am building my Eclips3d printer. I have tested movement and heat for the bed and hotend but I have not melted plastic yet.
My SmoothieBoard 5X has been working and yesterday I ran the tuning procedure to tune the PID parameters for the Bed and Hot End.
Today my smoothieBoard will not boot. I get only one led (VBB) on solid and a solid lit screen on my LCD panel.
I have a 5 V regulator mounted on the SmoothieBoard and a second regulator mounted on the LCD adapter card.
Measuring the voltage showed the 5V line on the SmoothieBoard at 0.6 volts. The voltage on the LCD adapter board is 0.6 v on the smoothie side of the 5v diode and 5v on the adapter side.
My first guess was a regulator failure. I connected a 5 V external power supply to the smoothieBoard without removing the 5v regulator. The voltage on power supply with no load was 5.5 v yet the 5 v line on the SmoothieBoard is still 0.6 V.
What should I try next? Is the next step to unsolder the regulator?
I noticed that a smoothieBoard led flashes when I rotate a stepper motor with power off. Could I have zapped the board when I moved the z platform for leveling today?

My problem was the washer on the z endstop shorting the endstop power.
