Thats really good, is that the same software as the previous project?
I made a 2 axis plotter from the chassis of a broken Roland plotter, just used the motors and mechanism, but my software is very crude. ( it was my first attempt at programming )
I have two steppers, and a pen up solenoid ( to actually move a nozzle up - its a machine for doming with urethane.)
I can set a pattern in the arduino and let it run, but I have to reprogram each time I have to dome another shape label.
It would be nice to have it connected to a pc and just call up the right shape from a file.
