Three axis microstepping drive and power supply board
ideal for 3 axis machine control
This high performance micro-stepper drive card was designed to complement our low cost AMC-E stepper,
standalone machine control card. It can be neatly mounted either above, below, or beside the AMC-E
stepper machine control card and connected to it via one ribbon and one 3 pin power cable.
The drive card incorporates 3 axes of motor drives for 3 axis machine control, machine safety circuits,
power supplies for both the AMC-E and the stepper drives, and status indicators.
Connections to your machine are made via plug in screw terminal connectors.
Intended applications include: engraving machines, routing machines, milling machines, lathes, and
dispensing machines. Designed for 3 axis machine control
Due to its capability of operating at high voltages and of supporting selectable high micro-stepping
resolutions, the drive is capable of running your machine very rapidly, smoothly and quietly, and over-comes
many of the resonance problems that occur when using coarser step resolutions.
