GerberCAM – Opensource PCB G-code Generator

GerberCAM

What is GerberCAM?
GerberCAM is an opensource software to convert a PCB gerber file to a CNC machine manufacture file(G-code).The following picture shows GerberCAM’s role in PCB prototyping process.

What are the features of GerberCAM?
GerberCAM currently support following features.
● Recieve gerber file in RS-274X format only
● Up to two layers(top & bottom)
● Pad holes automatic recognition
● Tool bits(drill,conical,cylindrical) generation & management

Contour path:
● Automatically treat closed loop as contour path
● Can determine contour path by thresholds

Toolpath generating:
● Single bit toolpath
● Automatically DRC and show the collided path

Pad types:
● pads with rotation
● Round
● Rectangle
● Obround
● Teardrop(● Track ● Arc)

Track types:
● straight line

Here are the snapshots of the current development.

GerberCAM is still a prototype.After three months of heavy development and testing it’s suspended.It has a fast generation time comparing to CopperCAM 2012,which is the CAM software I’ve been using to generate G-code for PCB prototyping for years.It can also handle some PCBs which can’t be supported by CopperCAM.

However,since I don’t have a CNC machine to test the software anymore so I didn’t continue to work on this project.I’ve been using hundreds of gerber files and thousands of times to test all current functions.There are still a lot of testing and verification work to do in the future.If anyone is interested in this project,feel free to fork it.Also I’ve been writing a detailed document about the implementation of GerberCAM on my blog.There are several opensource CAM software projects out there and I hope my works could contribute any help.

Here’s the link to the document.

gerbercam's Issues

Help to test your program

Hi, nice to meet you, I have not found another way to communicate with you.

I tried to clone this one softly, I have not gotten it to start working (I have Windows, the problem is in Qt5Core.dll). Could you help me? Do you think it makes sense for what I want to achieve?
Is the next:
I have very limited programming knowledge, even so I have managed to make my contributions of complements (route for trochoidal milling, trochoidal milling 3d, scale, generate threads,) to BCNC.
My interest is, within a larger project of a cnc with not so common utilities on which I am working, to generate the milling of pcb with two milling cutters: I have made progress, by means of complements for said program, (with the routes for a bit of 0.10mm and a bit of 0.7mm, I have managed to fill the areas where the 0.7mm cutter does not reach), but the process demands too much time from my computer.
I await your comment, a hug.
