The ability to sketch an equation curve is available in Autodesk’s more professional (and expensive) CAD product, Autodesk Inventor, but is missing from Fusion360’s. This tutorial details how you can get similar functionality using the Fusion 360 API. The Fusion 360 API (Application Programming … Continue reading
Strain wave gearing is known for its near zero backlash, compact design and axial construction. However it is not known for being cheap. This is why Simon Merrett created waves (pun fully intended) with his DIY 3D printed strain wave gear reduction first … Continue reading
After having some trouble finding a clear guide on how to create the correct tooth profile for a HTD 5M timing pulley I have decided to create my own. This method will also work for a HTD 3M or 8M … Continue reading
Which is better, a stepper motor or a brushless DC (BLDC) servo motor like these from Teknic (Clearpath)? The short answer: It depends on your application. If you only need open-loop position control (no shaft position feedback), are on a … Continue reading
In previous posts I built a prototype ‘TandemB’ which can be thought of as a 2D Delta printer in terms of its x and y-axis movement. This prototype could be moved about under its own power but that had no compatible firmware … Continue reading
In a previous post I proposed the idea using an unconventional kinematic system to translation movements in the x and y axis. This idea, which was dubbed ‘Tandem’, is similar to that of a delta robot with the key difference being that rather … Continue reading
Working in Tandem – Unconventional XY-axis layouts for 3D printing, laser cutting, CNC milling, engraving or pick and place.
Below I outline three separate concepts for moving in the X and Y plane with a specific emphasis on minimising the moving mass, maintaining high mechanical stiffness, reducing backlash and allowing two stepper motors to work in tandem. It is my hope that these concepts, … Continue reading
