| You can use a microcontroller (e.g. a PIC). If you want linear motion only you can use a step-dir IC and make a timer circuit with a 555 to provide step pulses. This way you can control direction and feedrate (with a potentiometer). You can't do a circle this way though... Nikolas |

| How versed are you in electonics? What are the x-y table inputs? You could precalculate all the information, or you could use a simple microcontroller such as an AVR or PIC. Phil

| www.parallax.com you can make a pbasic program and use continuous rotation servos to drive the axis (just an idea) It does require a windows pc with a serial port to program but after that it can run by itself. A starter kit is $80. not sure if their servos have the torque though... |
