I might have the answer to this myself.
I took an old printer out of storage and got bed leveling to work on the first try. I think I have a mechanical problem. I have changed to a e3d hemera extruder and made some other changes that I think are to heavy for my X-axis rails to handle. I can make the carriage flex with just moving the wires going to it. I will get some new beefier hardware and try again.

I wanted to do some upgrades to my printer (hypercube evolution) and set of on making auto bed leveling with 2 motors work before getting into DAA.
I am having some issues with getting auto bed leveling to work. I run probing and compensation 4 times and according to the bed leveling process I am getting pretty good results (I think).

I am using a BLtouch as a probe.
This does now show in where the nozzle of the extruder ends up though. If I set the nozzle at 0.5mm on the left side of the bed where I probe for the left motor and then move over to the right side my nozzle is about 1mm higher.
I can not figure out what I am doing wrong here...

Thanks for the quick reply.
Yes, I have a small burn marked on the attached image. I find no short between the stepper connections and ground. I have around 2 ohms on each coil and that is close enough to what the specs on my motors say.
I just bought a duet wifi the other day to upgrade from my ramps 1.4 setup. Wired it up to my ATX power supply with external 5v and ps_on. Works perfectly. Wired the endstops. Still works nicely, easy install wiring is so much nicer than the ramps board. Now comes the not-so-fun part... I connected my y-motor to driver 1. I try to move my y-axis in the console but all I get is a small "poof", burnt electronics smell, and a message "short to ground on driver 1". So I am guessing I burnt this driver.... 
How did this happen? This is an MPCNC machine that worked fine on the ramps board for over a year. Motor wiring has not changed. Power wiring is fine, endstops work but the driver just went poof when I tried to move the y-axis! I have not changed anything in the config file as of yet so I should only be driving the motors with 800ma. I have 2 self-built printers and one cnc machine so I think I have plenty of experience and I do not think I made a misstake, even though this is my first duet board.
Can this be covered by warranty or is this a "crap, I burnt €150 and I need to get a new one" situation?
