  1. Understanding Stepper Motors with DC Motor Theory

    An Introduction to Stepper Motors Part 1: Stepper Motor Theory and Design Step motors (also known as Stepper motors) are DC motors that move in precise, discrete steps. They contain multiple coils that are organized into groups called phases. By energizing each phase in sequence, the motor will rotate, one step at a time. (Hence the term ‘step motor’.) With...
  2. Troubleshooting Guide for the Geckodrive G540

    The easiest way to check to see if the Geckodrive G540 is working correctly is to connect only your power supply, a jumper wire between TERMINAL 10 and 12 and turn off the charge pump switch on the front of the drive. With only those things done you should get a green LED. If you do, begin plugging in your motors...
  3. What does a CNC Machine Consist of?

    Many people ask us what a CNC machine consists of. Every machine consists of the same basic four components. Here is a breakdown of each of the CNC machine components. A plasma cutter, router, mill or lathe are all going to use nearly identical electronics and software. The only difference is the mechanical assembly of the machine, and the tool...
  4. Tech Question: Can the Gecko G540 only put out a maximum of 1A?

    Tech Question of the Week: Q: I have a Gecko G540 and want to connect a 15-watt laser to the output 2. According to the laser manufacturer, the current is less than 4 amp (but can possibly be higher than 1A). Now, I was wondering will the G540 only put out a maximum of 1A or, will it start smoking...
  5. Tech Question: trying to get my G201X up and running

    Tech Question of the Week:  Q: I have spent a few days trying to get my G201X up and running. I can successfully drive it directly from Smoothstepper (ESS) however not via a few breakout boards. I have now tried three break out boards that use the Sharp EL/PC817 opto-isolators. After finding out these were possibly not fast enough, I...
  6. G320X P.I.D. Tuning

    The G320X can be tuned with either an oscilloscope or by ear to ensure that it is maintaining position while under load. The guide below is the quickest way to tune the drive without an oscilloscope and will result in a rigid motor shaft that will maintain position under any load. 1) Set the G320X following error limit switches to...
  7. Sub-Microstepping on the GM215

    Hey, we just published a new application note about one of the features on the upcoming GM215 - Sub-Microstepping. You can read about it here or on our website under the "Application Notes" section. The GM215 has many new features that can get the most out of your stepper motor and we will be posting about it here and on our...
