I have shared the Marlin that we are working on with a few guys that also have a very similar machine on the SmartRap forum.
They are testing it too. Their machines are also the same configuration of the hardware.
One of the guys is having a few issues, but I think the problem could be that he has an open z probe caused by the Bowden weight holding the probing mechanism to one side. I had that happen to me once and recognized the same problems that he is having.

Hi All, Nice to see you working on this. I just got a printrbot metal simple. It's using an induction sensor for autoleveling. It's never extended or retracted as i just sits about 1 mm above the nozzle all the time. The sensor detects the metal bed about 2-3 mm above it and acts as the sole z-endstop. It was really simple to measure the offset and enter it into the firmware using M212. I'm really impressed with this little printer. I've since purchased another probe to install it on my bigger printer. I'll let you know how it goes when I get it installed.

Here is the sensor: http://www.amazon.com/Cylindrical-In...J12A3-4-Z%2FBY
And here is a link where Brook Drumm explains how to set the offset: http://www.youtube.com/watch?v=lgVmN...hl2F_bmR01sjaA
Autoleveling is fun stuff.

It would be interesting to see how repeatable it is. Can you be talked into loading the M48 code and running the test?

I could be talked into it but my nozzle clogged last night so am out of business until then. Brook stated somewhere that repeatability was 0.1 - 0.2mm and this sounds right from what I've seen on the prints I've made so far.
BTW, Brook is a really nice guy and very accessible. I'm sure he would be very interested in your repeatability measurements and may even contribute to the cause. If you don't know the Printrbot story take a look. He did a 25K kickstarter a few years ago that turned into over 800K. He has done nothing but design newer and better printers since then and still sticks to the open source philosophy. It looks like he is selling over 50 of the printrbot metal simples a day now.
