Re: Pic servos

I have a pic servo controller that I tested. With it I have the rs232 link
and the pic step board for running the pic servo from the parallel port.
Here is how it works.
Using the supplied software from jrkerr you connect the serial port on your
pc to the serial interface board. You set the PID filter parameters and
enable the servo. Then you disconnect the serial cable and can run dos based
g code interpreter that communicate via the pic step to the servo board. As
stated previously, in another message. It runs slow on a 486-33 using the
parallel port. Using the serial port it is fast but you would have to write
you own software for controlling multiple axis. What is need is the rate
multiplier that he is comming out with. That should speed it up a bunch.
