The easyest way to solve the problem is to goto home then go back to where you where last. But this only works if you know where you where in the middle of a running cycle when using some kind of a drawing/cutting setup.
As for the easy single axis driver, you need only 4 darlington transisters which have built in diodes, You DONT have to have 4 resisters for the stepping phase controll when run directly from the parallel port but it is reccomended. As for setting up a home switch thats easy enuff. |
