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
Back in 2010 I developed an intense interested in understanding and eventually building a 3D printer. This interest took me down the path of reading all the material available at the time and purchasing a RAMPS (V1.2) which I used to control … Continue reading
How to take an image like this: and in one step generate the gcodes required to do this: All credit for cad.py goes to the original creator Neil Gershenfeld of MIT Center for Bits and Atoms and David Carr of Make Your Bot who optimised the … Continue reading
