A4988 and steppers My experience and mistakes

I've bought a few of the pololu stepper drivers A4988 to populate a ramps1.3 board used in printrbot. Before building the mechanics I soldered together the ramps board and plugged it all together with my arduino mega2560 and the drivers. Having tried to work out the best software combination with marlin version and either pronterface or replicator G I could not for the life of me get any action from the steppers in the control panel for either host software.

PzKw "Tammy"

Start me notI decided to do this Tamiya tankbot as a blog as there's been a few similar posts lately and It is probably one of the most common platforms about the net so I will see if I can do something different with it. But for starters I have built it like a start here robot although I will not call it that.
At the moment it is controlled by a pic16F690 but I intend to build different configurations using other micros as well.
