If you sort by most votes your in the first row for both catagories on mobile

Thanks everyone for the support and the nice things youāve said.
Great idea. I want to do more involving models that represent actual physical things. These patterns being represented by a swinging pendulum are really neat.
I found Peano curves on wikipedia that look a lot like hilbert curves. I like them a lot. I will have to dig in and see how to represent them in sfy. One of the biggest challenges isnāt finding new math equations to draw, it is keeping the interface easy enough it wouldnāt intimidate a student. I need to avoid turning people off who think they donāt like math.
Iām not sure which AMFMPM patterns youāre talking about. I do want to add the ability to make more of the patterns from equations and sin/cosine work great for that.
I would love to see more people with MPCNCs use sandify for making pen drawings. I added a section in the sandify wiki for tips to convert the patterns to pen drawing gcode, but I donāt think I have advertised that well. If anyone makes some sfy drawings, please share the gcode and some photos. It really drags me back to the keyboard to work on these kind of projects.

If I sort by most votes, My patterns are on top in both categories. It wasnāt that way even this morning. The voting goes for 2 more weeks, but hereās hoping we can keep it up!
You all are great.

We have not pushed you to #1 yetā¦we need reinforcements.
Call it Creativity for Dummies or something stupā¦ buzzy like thatā¦
Amplitude modulation, frequency ~, phase ~. Nice ways to draw wave patterns like on a water surface. Make it 3D and give it a perspective viewā¦
Decades ago (actually about four of them), I had an HP 9815 desktop computer and a matching HP 9872 four-colour pen plotter in my lab - a good opportunity for procrastinative late night fun with stacked sine- and other loops. Adding a Z-buffer to hide hidden lines precisely where they were supposed to disappear and re-emerge was a fruitful excercise for later activities with ray tracing applications. I have to learn how to let python plot gcode - hpgl was very simple in that integrated environment.
Any recommendations on how to get straight from plot x1y1,x2y2 ā¦ to gcode? Or, to become daring, dxf? That mumpy corner in my bookshelf?

Numpy and matplotlib are amazing packages. You can also find online juniper notebooks and it very close to a completely free matlab experience.
Getting to gcode is easy. You just have to be aware that you are drawing line segments from points. So 0,0;1,0 really defines a line, not two points. The much harder part is being reasonable with limits. The short solution is to just write out your gcode without worrying about limits and then load it into sandify as an import. The limits code is easily the most complicated part and the easiest to reuse.
G1 X(x) Y(y)
Thatās it. It will use the Z and feedrate from the previous move. Donāt put more than 3 decimal places, but sfy will handle that on final output anyway.

Thanks. I suspected that it is easier than thought. My main goal is to let my MPCNC (after remodeling it to Primo, all parts printed, no time to dis- and reassemble yet, but the sailing season is coming to an endā¦) do something useless aka art.
Numpy, of course, mot mumpy 
Thatās what I find when googoolating for juniper notebooks:
Juniper berry: Notebooks with Fruits for Kids and Adults ā¦
Oh wellā¦
I guess, for letting the MPCNC doing the hard work, Iāll rather create a point cloud representing the desired surface and then let meshmixer or something similar do its magic.
Thanks for getting me closer to the rails, btw

New day, new votes come on people!
This is the dude that made dual end stops possible, helped me on almost all my Marlin PRās, helped a giant number of people in the forums, invented Sandify (what a ton of the competition are using), and someone I trust to privately ask his opinion on major decisions, Marlin builder (heck me using github at all!), the Docsā¦the list is huge.
Put a little post in note near your keyboard, drop two votes everyday. Free to do, and makes me happy, thanks!

AWESOME! How else can we get the group in on this? I have a banner, pinned this post, FaceBook, any other ideas?
Jeff is like me, self promotion is not his strong suit. So I am more than willing to do what I can to make this happen.

Maybe enter everyone that votes into a draw for some fancy V1 swag. Like a hat or t-shirt

I can do that, how do we prove votes? New thread, screenshots with a date?

I donāt think the rules allow for rigging it, or buying votes in any way. I appreciate the offer, but it does need to stay fair.
