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
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
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
As cad.py works from images, your not restricted to just PCB designs. You can also import any black or white image or text. As long as its white lines on a black back ground it should work. So there is … Continue reading
My Mantis inspired repstrap/CNC mill is finally up and running. All the mechanical parts were scavenged used for the repstrap were from old printers. The total cost ended up being around $140AUD. This was all spent on the electronics and includes … Continue reading
If you have pulled apart a printer, fax or scanner then there is a high likelihood that you have found a few photo interrupters. Some of these may be pre-packaged in a plastic housing with three wires attached which you can modify to use … Continue reading
