3D Relief cutting with 3020 using a greyscale depth image
-
I was talking to @robert today about cutting 3D shapes on the 3020. A while ago I did an extensive search for a free and open source 3D cam software, but I could not find anything that I could recommend. However, I did not realize that LinuxCNC has a really nifty and nice feature built-in for generating G-Code based on a grayscale raster image:
For this test, I am using an image I found online while searching for “greyscale depth”:
@pierre has been taking some pictures along the way, I hope he can post them here.
So far it looks pretty promising, but this is a slow and long job. I am very curious to see how much of the details will show. Stay tuned for more update!

Not terrible for the very first attempt. There is a lot of room for improvement, but I call this a success.

@arasbm As I recall the part was about 4" square, maybe 3/4" deep… How long did it take to cut, using that wee 1/8" upcut router bit?

That looks great for a first run, and the youtube tutorial was very interesting. The detail issues look to me like a bit issue. A ball-end bit would be great to get for this. Thanks for doing this, I think it will be useful for a lot of projects.

I was in yesterday to do some projects on the CNC and after a couple hours or frustration, finally figured out that the speed controller has come loose from the control box, and I don’t know what pin configuration was used to connect it originally. If someone who does know (Aras or Pierre, I think you both were in on that) could re-connect it, I would really appreciate it. I am trying to get more proficient and do a demo on in for the kids next Monday.
BTW, I orders a couple of dozen new bits for it a week or so ago, so we will have some more options for projects, like some Ball-End bits, more engraving bits and a set of sized bits for a bit more precision. I’ll bring them in as soon as they arrive - can’t wait to try some of the greyscale 3D relief projects with a ball-end bit, which should allow for much greater detail.

I probably won’t have much chance to work on it until after the haunted house. I think @Chris documented the correct wiring in this thread:

When we re-wire it, we should take some pictures too.

@pierre is correct … at least it is correct as far as we got. Never played with various router speeds or basic router control from the cnc software.

@arasbm and I found 5 extra minutes to look at it today. I’m pretty sure it is up and running again. Sorry to have taken so long to fix it.

Pierre, that is great. You shouldn’t apologize, I appreciate you taking care of it.
