Transformation utility to rotate coordinates in G-Code files
Coordinate rotation is useful when making PCB with 2+ layers. Based on a reference points (which are included in PCB production files during DIY manufacture) it is possible to layout different PCB layers during drilling, UV exposing, gluing &final cut. Each time PCB was dismounted from a CNC and mounted again, it will have some angle of rotation over a zero point (X=0, Y=0).
Manual measurement of this rotation angle is performed with help of laser module mounted on the same CNC. For each...
A robotic DIY styrofoam cutter consisting of one rotational and two translational axes. It cuts a variety of shapes out of styrofoam-like materials using a hot wire. This project documents the necessary hardware and software parts.

Its goal is to further develop hardware and software into an user friendly application.
piCNC is a PIC based stepper motor controller for use in CNC applications. Its software and hardware development is completely open source and community supported.
