G251X Digital Step Drive

$65.00 As low as $39.00

With a cost as low as $39/ axis, the G251X is our most popular product for small to medium sized stepper applications. With an easier to use 3.5mm terminal block for end-user wiring the G251X is a favorite of hobbyists and OEM’s alike. Its small size (only 1.65” x 1.3” x 0.585”) makes it a perfect candidate for small platform CNC machines, 3D printers or any small to medium power automation application.

At a native ten microstep resolution the G251X does not require extremely high input frequencies to operate at high speed but offers enough resolution to match the accuracy of most stepper motors (+/- 5% of one full step). An adjustable low speed smoothness trimpot compensates for motor nonlinearity at the low end while midband resonance compensation ensures reliable torque output through the midband dropout region.

Full Step Morphing is entirely unique to Geckodrive products and can transition your motor to a true full step motor between 4 – 6 revolutions per second. No software changes are required to take advantage of this and accuracy will not be sacrificed. This results in a 30% increase in useable torque over a drive that does not morph.

High quality and high efficiency components, from the small footprint IPAK MOSFETs and oversized gate drivers to the low-power CPLD  means the drive consumes very little quiescent current and requires minimal heatsinking. An attached hard anodized heatspreader electrically isolates the MOSFETs on the bottom side and makes it possible to attach the G251X to any heatsinking surface.

All Geckodrive motor controls come with our industry leading three-year warranty and free US based technical support. Should a drive sustain damage in the field we offer repairs to minimize your downtime. If you are unsatisfied with your purchase we offer a 90 day return window.
