I then wrote a simple bash script to generate gcode movements (rand x,y,z from -50 to +50)
It moves!!! in its expected delta way!
You need to have the end stops enabled and attached, the first thing the rostock firmware wants to do before any moves is home upwards to the end stops.
I got around this by powering up without end stops (since my end stops are normally closed) So it presumed that power on positions was (0,0,0) I then attached end stops to allow it to move with out warnings.
Secondly, its really loud!!! Most of the time you have all 3 steppers moving, and the wooden base seems to be amplifying the sounds. It may get quieter once I add the side boards and turn it up the correct way (currently running upside down)
Just some random moves
