Ask Me Anything Wednesday October 14th & Industrial Stepper Drivers vs. STEP400

Our Ask Me Anything (AMA) is coming up tomorrow! This is a series that takes place on Crowd Supply's Discord server. If you have any questions or simply some interest in STEP400 or stepper motors, please join us! Also, the other day, through an unexpected connection, I had the opportunity to speak with someone who works at an industrial stepper motor manufacturing company. This update will be a recap of our chat, and I think it will be very helpful in understanding what STEP400 is and what it isn't. Read the full update.

How To Get Started With Mechanical Parts

Hello everyone. Once again, thank you all for your support and interest! This time, I recount my visit to TASKO, a company that makes a lot of machines for exhibitions, theatrical performances and video filming. They showed us various ways to incorporate stepper motors into practical mechanisms. Getting into the mechanics part of stepper motor projects presents a different kind of difficulty from electronics or programming. In this post, I'd like to show you what happens next, after making the motor spin. Read the full update.
