Open Source C CNC Software

LinuxCNC controls CNC machines. It can drive milling machines, lathes, 3d printers, laser cutters, plasma cutters, robot arms, hexapods, and more.

AVRCNC is a CNC-Controller based on an ATMega8 and some other (cheap) hardware. Main advantages compared to L297+L298 are: - simpler to build - easier to expand - mega8 controlls motors directly - no time-critical tasks on PC

CNC-Suite is an Free & Open Enviroment for 2D and 3D CNC-Machines

Cnc's IP Data Volume Report: Logs IP to IP contact, number of packets, bytes, time of contact, Ethernet too! View via local web interface. Very simple for those who want to view who your computer is contacting the most!

4.4BSD-based UNIX-like operating system for CNC / machine control applications. Using low-cost hardware, FabBSD can be used to control a wide array of CNC milling machines, lathes, routers, process-control and automation equipment.

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 reference point, travel CNC with a laser module and fine tune X/Y coordinates to target at the center of a drilled point (laser light will dim out). Write each of the measured point's coordinate with corresponding ideal (original) point coordinate into the reference point (text) file. Then use this utility with source G-Code file & measured reference file to perform transformation into a destination G-Code file. Each X/Y coordinate in "G0", "G00", "G01" commands will be rotated by a calculated angle.

Universal CNC (Computer Numerical Control) system with accompanying communication and graphics libraries

RoboFac is a software system for controlling a hexapod, also known as a Stewart-Gough platform. It features a G-Code interpreter for CNC machining.

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. Don't miss the follow-up project at http://raumschaum.org Its goal is to further develop hardware and software into an user friendly application.

motion 5 is a specialised variant of GRBL which is focused on motion of up to five CNC axes and laser processing instead of milling. It supports ATMega MCUs running with up to 20 MHz and provides jitter-free pulses with a frequency of up to 38 kHz. Wherever usage and handling of motion5 is different to original GRBL, this is described in Wiki. For the G-code commands please note that motion5 supports more axes which are named "A" and "B". So a GRBL-command "G1X10.0Y20.0Z10.0" which moves its three axes would be e.g. "G1X10.0Y20.0Z10.0A20.0B30.0" in motion5 to move all five axes.

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.

Project aim is to translate RS274X files such that it is easy to use the RS274X file content to automaticly program a home made CNC milling machine to mill Printed circuit boards.

Tinymotion is an dedicated motion control hardware/software combo for cnc machine control applications. http://www.tinycontrols.com
