Overview
The Soigeneris STDR-4C stepper drive is a full-featured, compact, 4-axis stepper drive system. With its 120V/240V operation and a careful selection of quality components, you have a solid performer that is also very economical to ship worldwide.
The STDR-4C was the first stepper control to come fully integrated with the SmoothStepper motion control board. The SmoothStepper offloads all the timing critical functions from the PC providing both a superior step quality and faster step rate than the parallel port is capable of. A stable step pulse stream allows you to achieve maximum performance from the rest of your system and it allows for using laptops and smaller embedded motherboards.
Designed to be easy to use and easy to upgrade all signals are brought out to the rear panel which makes connections and upgrades easier. A 48V power supply is used to power the stepper drives while two separate auxiliary power supplies are also included: a 5V supply for the SmoothStepper and a 12V supply to power external sensors. (Separate isolated power supplies maintain the signal isolation provided by the G540.)
We can also provide a complete drive kit with the STDR-4C bundled with our stepper motors and a set of high quality, 20AWG, 8', shielded stepper extension cables. We suggest the following kits for common types of CNC machines. Contact us for kits with different length stepper cables.

Features
The Soigeneris STDR-4C stepper drive is a full-featured, compact, 4-axis stepper drive system. A careful selection of quality components is housed in a heavy-duty aluminum enclosure. A high-quality 48V, 320W power supply feeds the stepper motors through a Gecko G540 drive. Two auxiliary power supplies are also included: a 5V supply for the SmoothStepper and a 12V supply to power external sensors. (Separate isolated power supplies maintain the signal isolation provided by the G540.)
The design philosophy of the STDR-4C was to provide a very solid stepper drive system that was easy to use and easy to expand. We started with a heavy duty aluminum enclosure, a high-quality 48V power supply, and the venerable Gecko G540. All the signals from the G540 were brought out to the back panel to make connections easy. To keep things cool a unique thermal control baffle was used that ensures fresh, cool air is drawn in the bottom and the warm air is exhausted out the top. For systems using motors which draw more than 3A, an optional heat sink is also available for the G540.
A large illuminated power switch starts things up and to help ensure safety, an industrial E-Stop switch was fitted. The E-Stop switch removes power from the main power supply and spindle output while maintaining power to the auxiliary supplies. Two relays were fitted, one supplies power to the spindle outlet and the other controls a set of auxiliary contacts on the back panel. Finally to provide the best performance possible a Smooth Stepper was added in.
