Modifying Marlin Firmware to work with a TandemB

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

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
