4 Axis 256 micro stepping Driver + Controller measuring only 2.25" x 2.25" x 1.0!
AllMotion's EZQUAD HR Stepper was designed to allow the rapid implementation of multi-axis stepper motor solutions in products requiring automation and encoder feedback.
Measuring only 2.25" x 2.25" x 1.0" (57mm x 57mm x 25mm), the fully intelligent stepper motor Controller + Drivers runs 4 fully independent stepper motors (see wiring diagram). Operating from a 10V to 40V supply the controller regulates to any motor voltage via software command. (Eg 6V motor can be run with 24V supply). Commands can be issued from any serial terminal program (such as HyperTerminal) or the EZStepper Windows application.
The EZQuad HR Stepper will drive 4 motors at 1 Amps each with a setting of move current m=50 %. However, with careful selection of motors and/or improved cooling and/or low move time duty cycle it is possible to run motors at 2 Amps at m=100%. See Command Set for details.
The Commands are intuitive and simple. For example, the command A10000 will move the stepper motor to Absolute position 10000. (This communications protocol is compatible with devices that use the Cavro DT or OEM protocol.)
The EZQuad HR Stepper is also capable of stand-alone operation with no connection to a PC. It can be set to execute a preset string of commands upon power-up (i.e., only power is required in this mode). The Commands include nested loops and execution halt pending a switch closure, which is useful in stand-alone applications.
The EZQuad HR Stepper Motor Controller will typically work with any motor that is 3" or smaller (size 23 or smaller). Our Starter Kits enable a first-time user to make Stepper Motors move intelligently in less than half an hour.

Q & A
EZQUAD HR Stepper Motor Controller/Driver Q & A
It typically works with stepper motors of 3″ or smaller (size 23 or smaller). You can run lower-voltage motors on higher-voltage supply using software voltage regulation—for example, a 6 V motor on a 24 V supply.
