Construction of a TandemB Prototype

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

Constructing the ‘gunstrap’

I have started to build the new larger Mantis CNC inspired repstrap. The plywood i’m using for its construction is, oddly enough, from 8mm rifle ammunition boxes previously used by the Australian navy. Its 16mm thick, easy to work with and … Continue reading

Rethinking the Mantis Repstrap.

The Mantis CNC is a well thought out and very easy to construct PCB mill. Unfortunately, as it was originally designed as a PCB milling tool its build area is very restricted both horizontally and vertically. Because of this, and a few … Continue reading
