This driver only needs 4 wires from your stepper. To do this, I’m using a cncshield. I think there are 4 or 5 samples. The most common steppers have steps per revolution, so all movement is in 1. Placing two jumpers across the line marked Y will clone the 4th axis to Y. Exactly why this is is pretty complex, but if you want to know more about it, you should really read this: Your sketch will compile, upload, and start running on the Arduino.

Unfortunately the mechanical rotary axis is not very accurate. It is even does acceleration and deceleration, supports multiple drivers at once, and most importantly it is non blocking.

Keep this in mind when adjusting the current limits. The big easyDriver is the big brother of the easy driver we wrote about last year. I know this is old, but I arduno using the same controller, and something you’ve done has me confused. So we need two pairs of wire that have the highest resistance in the group.

The G201X Digital Step Drive

Is this a possible scenario? The version I have here is barebones with none of the examples. Better yet if the Arduino can be programmed for various steps then I could have switches for say 2 degrees or 5 degrees or 90 degrees etc.


Microstepping breaks down that step into smaller micro steps. Meaning, you can be moving your motor as you are reading from a sensor, or turning on lights etc. Our drives are designed for stepper and servo applications and we are constantly developing new motor control technology. Enable, direction, step, ground.

Our technical support is well versed in a variety of applications and is always available to assist you during business hours.

John, Thanks, that explains it. Gecko Stepper Driver Control. Adjusting the microstepping The Big Arduibo Driver defaults to 16 step microstepping mode.

Using an ohmMeter, pick one wire at random, and test it with the others until you find a pair that shows resistance of a few ohms 1 — ohms most often.

JavaScript seems to be disabled in your browser. For grblI can’t do this so have to run three separate wires for X,Y and Z.

John, Thanks for the reply. They are perfect for automation or any time you need a motor to turn to a specific point, at a specific speed, in a specific direction.

Gecko Stepper Driver Control

You’ve probably noticed this by now, but the male headers on etepper CNC shield beside the V terminal block, allow you to clone the 4th driver A to any of the other three axes. The library even keeps track of the position of the motor. If you have a 4 wire stepper, awesome!


Help with Control of a stepper motor using Arduino,Gecko drive and a switch. Check out the chart on the side to see how make the adjustments.

A Gecko like this one. To find the correct 2 wires, we need to locate the 3 wires from each coil. The ends of the coils will have twice the resistance as the center to an end. It works well and I’ve been successfully creating gcode using mostly CamBam. Shop Our Top Products.

Both motors would turn in the same direction so changing the wiring on one motor is required to get this direction reversal. Code For the arduino code for the driver, im going to be using AccelStepper Library. John, I downloaded the software and investigated the Example programs just as you suggest. All neat and tidy in a box.
