Re: SIMPLY CIRCUIT TO DRIVE STEP MOTOR

Woodknack,

This method of driving the stepper as a synchronous motor will give
you a fixed speed. (72 rpm for 1.8 degree motors)

You may prefer to get one of the kits for a stepper driver, which has
an onboard oscillator (ramsey is one brand). This way, you can change
both speed and direction of your leadscrew. Many of these kits use
the 5804 chip which can have up to 35volts dc, and provide current of
up to 1.5amps per phase (heat sinked and fan-cooled). This will be
plenty for your taig screw, IMO. AND,... you can upgrade later to
cnc, if you wish.

Hope this helps.
