In the end this printer is a typical kossel. If you search for kossel calibration on youtube you will come up with a few videos to help. That's how I did it.

If you do decide to flash your firmware, do yourself a favor and don't do it the "easy way" as given on the forum as this has the potential to brick your board. Do it the "hard way" with the arduino ide version 1.0.6. Don't be concerned that it won't work with the latest version of arduino. It won't and that is all there is to it. Don't try reloading a different bootloader. That way lies madness.

Take a bit of time to learn about the delta geometry. It is more complicated than one would think and can help you understand problems you are having with the printer. This also is on the web somewhere.
