Y-axis FIXED!

Thanks to some hints from the kind people on the RepRap.org forums I found out there was a bad connection on the bottom side of the PCB. Some solder bridged 2 connections due tho the short circuit I caused before(including smoke & flash). After cleaning up this bridge all electronics work fine and my X, Y and Z axis move smoothly!

This means I'm back on track and hopefully be printing something soon...!?
Next Step: Leveling the print bed
