Preparing A Drawing for the CNC Machine

 



First I went through some planning stages with the composition I wanted to use.


When I was happy with the design I added it into Rhino to begin tracing the layers.
I had to trace each layer using curved lines, then hatched them to get a good visual of what they would look like with infills over each other. My hand hurt from all the clicking but I finished it in an hour.




This was the final image before I started introducing the numbers to the background.

For the numbers, I wanted to generate a random sequence in Rhino to fill in the background, as well as insert a sequence in binary to spell something out. This didn't end up working out for a few reasons. I'll get into why the numbers didn't look how I wanted them to below.

I started using the rectilinear fill to create grid patterns. Two fills per layer, one at 90 degrees and the other at -90 degrees. 

HELP NEEDED:
For some reason one of the curves did not register with the fill. This is the error message that it generated. I don't know why this is, because the hatch fill worked fine in Rhino for this section.




I tried baking the lines that I COULD produce, and here's why I decided against the numbers in the background. The size of them meant they weren't legible in this fill unless I outlined them, but that drew too much attention to them. Here they just look like little gaps in the pattern.


I managed to add in select few curves from the darkest layer (just the shadows around the eyes) but still wish I could fill the rest. 

And to experiment I tried a scribble fill as well. It produced strange and scary results.



So then I gave up on finding what was wrong with that one curve. Because it let me hatch that area, i just did that instead of using the rhino fills. 

Came up with this design finally.

FEB 26th / MAR 07 - CNC DRAWING

Image
The progress I made since the CNC demo has been slow comparatively. I had to clean up my files and organize the layers into colors to prepare for printing. This week I am preparing to try my file on the CNC machine. That is tomorrow's project because Thursday morning was the only time I was available. I will update this post after that process. On FEB 27th and MARCH 3rd I printed my drawing on the CNC machine. Overall I'd say it took 4 1/2 hours.  The first two layers, I did in one session. They had wider grid infills but covered more space overall so they each took about the same time as the final layer, around an hour and a half each. The first layer was done in red and green. I switched to green because the pen ran out of red ink. I was using a color changing pen for ease of color switching. After the end of the first print I switched to blue for the second layer. I didn't have to re-home it or anything because I was just clicking a button on the pen. The blue ink lasted...

MARCH 09 - NONLINEAR FDM TOOLPATHS - Pasta Experiment

Image
I decided to experiment with GCODE by making a bowl of pasta. The trick is that the pasta is going to be printed in the air and droop into the bowl from above. Hopefully without melting everything that came before it? Here's how I set it up: I used the trick with the Spiral + Intersect on a sphere I cut in half, then used the rectilinear fill definition to cover the bottom of it. I joined the two curves to make a sort of imperfect (and very tiny) bowl. The "spaghetti" is just two other curves I projected in the space above the bowl. As it prints, I'm hoping it all spirals into the bowl below like noodles that have just been thrown in there. I also took a look at what this might look like with 0.5mm wide pipes. From there I just put the curves into the gcode generator and tried it out in NC Viewer to make sure everything printed in the right order. The organization by Z axis made this process easy to set up. Here it is on the printing bed as well.
