Sharing the latest piece to come off the polargraph.

Grid size: 6
Pen tip: .25 (ball point ink)
Sample size: 2
Drawing: Frequency modulation
Final Dimension: ~27cm square
Motor Speed: 400
Acc Speed: 300
Time to completion: ~5 hours

Had a small hiccup on the line that left the gap, but it adds character. I think because I've got the grid size so small, the waves aren't quite square. Not sure if this is a product of gondola wobble or if I need to slow down the motors (which would also reduce wobble I suppose). Its consistent through the entire print, so it works well. A bit of a blend between squiggles and square wave. At this resolution, it gives a well blended image from a meter away (as opposed to 5 or 6 meters at grid size 20) Done for a friend of mine.

I'd like to see a drawing with pixels scaled to, say, 1.4. It really would be a new scribble/squarewave hybrid.

Wait....how do you get a grid size of 6?

It just got all arcane up in here.

If I say your name (your true name) three times, whut heppins?

and when I set the controller.grid.size at 3, I heard the voice of the fourth beast say, "Come and see". And I looked, and behold a pale horse! and his name that sat on him was Death!

You guys are too funny. I've seen too many possessions of the gondola to count. Thats why I switched to a 50lb braided fishing line! It kept breaking the string everytime it did that. Now, the weakest link seems to be the motor itself as it just sits there and skips steps.

If you want to see some real wizzardy, the paper thats tucked behind the actual drawing has a square that you can make out near the top of the machine. Thats grid 3. Havent done an actual drawing with it yet, but line to line is ~.97mm
