I have 5A camtronics drivers, but one of the PIC chip went bad, has anyone had this problem? Where can I get cheap 5A chopper driver's?

Hello,

My new Stepper3 HPPWM board will easily drive motors at 5 amps. The board is a unipolar high power pulse width modulated board that is capable of at least 8 Amps per phase.

I have extensively tested it, and am in the process of having it manufactured.

The specs are basically:

3 Axis
PWM Running at 30 KHZ
Potentiometer current adjustment
5 Limit Switch Inputs (can be used for home, limit, and estop).
4 Aux Relay Drivers (Open Collector type)

The interface is a parallel port interface.

The selling price will be $349.

I have not yet written the user's manual, so I cant yet forward it. I expect the board will be manufactured within the next few weeks. The dimensions of the board are 9.5" X 11.0 "

If you are interested, or have any questions, please let me know.

Thanks
Steve
