I have taken the drivers from the Y slot and put them in the X slot. Then I set the Vref for X and they are working there. I also plugged in a spare stepper motor in the Y slot and get no response. When I tried that same motor in the X slot it works fine.

Now I am down to troubleshooting the board. I guess I am just looking for some advice. I used some breadboard jumpers and measured the VDD pin on the RAMPS slot and was getting 4.88VDC which was the same as my other driver boards. My enable pin however is at 4.67VDC and my other boards are at 4.88VDC Is that low enough that it will keep the driver from turning on? I'm kinda dead in the water with this. Looks like I might need a new board. I might be able to reflow the components on it but I don't have a hot air station handy.
