Hello Forum members,
Please check my YouTube channel where I showcase SandeepsCNC software which is completely developed on a single board computer, raspberry Pi. Currently I am distributing the Licenses for Free. Request you to check whether it will be useful for your projects and I will be happy to hear your inputs and suggestions in promoting my work. Thank you.

From what I gather from your website this is essentially a grey-scale image to a rasterised 3d relief carving? No G-Code interpreter?
That's interesting for some, but not for me. But it's an interesting application of a RPi, which could probably be a good standalone device suitable for small scale machines. With the right software!
The purpose of this software is not to use G-code. For 3- axis CNC it's really not needed. Even for simple tasks you spend so much time in writing the code or converting the cad/cam.
Please look at other video's. Technically you can do all which you do with G-code code but with ease and fast.
I think we need to agree to disagree on this one.
Well, I respect your opinion to disagree :)
Sandeep, I don't think people really want to spend minutes watching a video to get information that could be read in seconds on a website. As a CNC and Pi user I'm interested in what you have, can you provide a link to your website please?

Thanks for the link. One question: you say that the machine doesn't need g code, and can cut simple shapes from the app. But, while that's useful, often one would also like for example to import complex shapes from CAD/CAM - is that not possible?

You can get any 2D shape for CAD/CAM saved as an image and give it to the SandeepsCNC software. Using Image based Edge detection methods it will create the tool paths. I am sorry, I didn't have a video to demonstrate it but the functionality is there.
The main purpose of this software is to help CNC Machine builders to reduce machine building cost and do Complex 2D and 3D relief carvings simple and easy.
For 3D CAD/CAM shapes, you certainly need G-Code. There are already free G-code runners available for Raspberry pi. But you still need to pay for software to generate the G-Code.
I will integrate G-Code interpreter in the SandeepsCNC software only if there is lot of request from users.
Thanks
Happy to test when this is available.Quote:

I can already import an image into LinuxCNC and generate a toolpath from it.I would be quite happy to lose the bulk of my old desktop computer and replace it with a Raspberry Pi and might just do this when I am convinced that LinuxCNC will run on a Pi.I also like the idea of a control system not being dependent on one individual as illness or misfortune could prevent them continuing with the project.
Hello Doddy,
Once I create the video, I will let you know.
The reason I haven't created one yet, even though the software has the functionality, is because my diy CNC bed is not flat and this is causing the pcb milling not possible: either it is completely cutting the pcb; not just the copper, or not cutting at all because of uneven z.
I see this problem with several DIY CNC machines. So I am adding a function in sandeepsCNC software to map Z before any cutting or carving.
Thanks
Sandeeps - thanks, makes sense. I've plenty of painful experience in isolation routing PCBs so I can appreciate at least some of the issues that you might face.
