G540 4-Axis Digital Step Drive

$289.00

Our first multi-axis drive, the G540 is our most popular end-user focused product. Capable of driving four independent motors with its discrete internal motor controls at up to 50VDC and 3.5A per axis, it can move motors ranging from small NEMA 17s to large NEMA 34s. The motherboard has an integrated DB25 connector for connecting directly to a computer via parallel port or a third party motion controller. Motor connections are made through DB9 plugs, which are included with the drive, and current can be set differently on each axis via a current set resistor.

Motor connections are made through DB9 plugs, which are included with the drive, and current can be set differently on each axis via a current set resistor.

The G250X, the heart of the G540, features proprietary anti-resonance and motor smoothing techniques. At a native ten microstep resolution the G250X 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). Full step morphing at higher speeds transitions the drive to send a true square wave when the benefits of microstepping are no longer present. 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.

Four general purpose inputs on the motherboard are meant for limit switches, home switches, touch probes, torch height controllers, and other machine accessories. Two general purpose outputs that can run up to 50VDC and 1A each allow for the use of relays, coolant pumps, indicator LEDs, or other high current accessories. An integrated VFD (Variable Frequency Drive) circuit outputs a proportional 0 – 10VDC signal based off of an input voltage, typically used for controlling spindle speed.

The G540 also has a NC switch on its emergency stop pin, making sure you do not power your motors until your machine is clear. A secondary safety measure, the charge pump or watchdog timer, will not enable the drive until a 10kHz signal is present on one of its DB25 pins. Both features can be disabled by the user for non-computer-based applications.

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.

    I have used this drive since 2012 and it works just as well as the day I bought it. It is damn near bulletproof.

    Being a Manufacturer of CNC Plasma Tables I use the G540 exclusively. I have been using this product for 7 years on all the tables we build. This small all-in-one package is well built and reliable and has the best warranty in the business. Detrick Design & fabrication, LLC

    I've used the G540 on workhorse machines in the past never ran into an issue (except when I sprayed my control box with water). Bought another one recently for a personal project and it was a breeze to setup. Great price for 4 high quality drivers in one housing, and a key chain too!

    After months of struggling with stuff that was made and owned by a China company, I went with this and my problems disappeared.

    I had nearly given up with my CNC DIY kit, but Gecko saved the day. What a wonderful product and support.

    I know I am the customer, but I can't thank them enough.

    I've bought & used a few of the G540's over the years, and I keep coming back. It's simply the best, with the best warranty and customer service. Very personal & professional support, always! The G540 is a very clean, compact package that simplifies your controller build.

    Bought the 540 to replace a chinese BoB that came with some other components on a used cnc router framework. Got tired of dealing with china via email & very little support. A phone call to Gecko engineer sealed the deal. Just finished the install & tuning. Hope to be making chips in the morning. Warranty & great support mean a lot to someone used to dealing with lots of different brands of metal cutting machines at work.

    Service is fast and the product works very well, like the compact size and the plugs ( had to install for mine to work ) I bought another one to replace an older driver on another machine.

    I got this to replace a LS7400 vintage single pole driver for 4 motors. went from 51oz-in which was just enough to run consistently to 240 oz-in. which can bend things if you let in jam.

    The hardest part was soldering all the blamed pins and making up connectors for the motors. Gecko's setup file immediately got the machine running again. It took a bit of fiddling with accelleration, speed, and other settings on motor tuning to get the best performance.

    For new machines HaydonKerk makes some very good parts all the way from light duty antibacklash nuts to ball screws and nuts capable of several hundred pounds of force.

    Zero training on using or operating a CNC machine and no prior knowledge of how they even operated. Did a little research and purchased this for my initial attempt at building a home made CNC machine (Plasma later converted to spindle). Tons of documentation/videos available which made my attempt successful. I only wish they had a 6 axis version as I am looking to expand!

    the g540 has to be one of the best stepper controllers available.

    everythings documented, its robust, easy to install.

    had one for years on my little CNC mill, so far, its survived all the abuse i can hurl at it, and ive only had to replace the fuse.

    for ease of setup, nothing else can quite beat it. just dismantled a 3d printer to make a coil winder.

    10 hours of sifting through arduino nonsense just figuring out what BOARD i even have...

    i finally give in, and steal the gecko off the mill.

    ten minutes later im spinning motors. hopefully the maths works out and im calibrated...

    now, i just gotta write the g-code bit. oh dear.

    sadly, the gecko doesnt do that for me...

    This is the second G540 I have purchased, They work great. I just recently updated my router to an ESS smooth Stepper. Very easy to setup no issues at all.
