An Introduction to Stepper MotorsPart 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 a computer controlled ‘stepping’ you can…

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 used to cut or shape the material. Do you have a… -
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 when currents get higher than 1A? Is there a fuse to protect the G540 for this? Thanks in advance… -
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 tested a small breakout board that uses the TLP281 without…
