Thanks for the warm welcome -- it's appreciated. Why do I get the distinct impression that knowing about this place will end up being very expensive, and very interesting.
Now...back to my question.
I understand how to change out one drive system for another -- that's no big deal. But, how would you make sure that the commands it receives, are still translated in a 1:1 manner?
i.e. You send an HPGL command which tells the plotter to "draw" a line by moving the carriage 2 inches, or 800 steps or however it's indexed. Now, the controller internal to the plotter generates the necessary pulses that drove the toothed belt, that moved the carriage 2". How would you do the (mechanical?) conversion, such that the resulting movement remains the same?
