I can't help with the technical part, but I want to say that's really cool. You need to have some batteries on the gondola, then?

Pausing a drawing, when printing form SD card
I wanted to ask whether there's the possibility to pause the drawing process when printing from the SD card.
(When using the controller software, this is easily done).
Yesterday I was printing a larger piece (from SD), and the pen ran out of ink. So stupid :D - I had to decide whether to abort the drawing, or let it continue.
Thanks for all help!

Option to show reduced vector/bbox for "MOVE VECTOR"?
I'm currently working with SVG data that has 200k+ lines in it. Once the controller has exported the queue, I use the amazing polargraph-optimizer to be able to reduce the commandload to less than a fifth (!) of the data.
Before this though, while still in the polargraph controller, the huge file is cumbersome to work with; in my case, especially so when moving the vector to its final position on the paper. (the software still is insanely responsive, considering the load it has to juggle!)
There is the command to not show any vector data, but would it be possible to optionally show some kind of "limited" version, e.g. just the bounding box, of the vector data as well?
Thanks!

Looking good :)

Re: Pausing a drawing, when printing form SD card
With PolargraphSD, you just tap the button on the screen to pause it. Otherwise no, once the control switches over to the file on the card, there's no stopping it until it finishes.

Hyptnotik! Like a 3D Printer you can watch it drawing during hours and hours...

Re: Option to show reduced vector/bbox for "MOVE VECTOR"?
There's not anything built in to reduce the detail during move, but it's quite straightforward to reduce what it displays during a "move vector".
The code that does that bit of drawing is at https://github.com/euphy/polargraphcontroller/blob/master/polargraphcontroller.pde#L1000
Replace that line with:
int increment = round((pointPaths.length/10.0)+0.5);
for (int i = 0; i<pointPaths.length; i+=increment)
Where the 10.0 is the proportion of lines to draw. So 10.0 will draw one in every ten lines during "move" time. Changing it to 2.0 will draw every other line. 20.0 will draw one in every twenty lines. Etc.
Is that any good?
Maybe it should only kick in over a certain number of lines ... so only if the artwork is more than 10000 lines or something like that.
I might roll something like this into the next release.

Filling polygon?
Hi, do you know a way to fill a polygon? I dream of finding a way to do that... The only way i know is with CAMBAM cnc software, you can ask to pocket a closed polygon, and i search a way to doing that to prepare SVG files for the PolarGraph...

Re: Filling polygon?
If I understand your question correctly, the easiest way I know is to use the Eggbot Contributed Extension for Inkscape called "Hatch Fill".

Re: Filling polygon?
Yeahhhhhh that's what i neeeedddd!!!!! Now i know it's possible i will try to code it in Processing :)
(and use Inskape plugin for the moment)

Re: Filling polygon?
argh think i can't do it myself lol... will use Egbot plugZ :D

Thanks for this! I've been busy the last days, but will experiment with it, and get back here.
Thanks for your support!!

A 'reduce density while moving enormous vector or .g files' function would be lovely in a future release Sandy, especially with mega Death to Sharpie outputs.

Re: live drawing
HI guys, i'm still trying to do this.
Now i can receive "ready" messages and "motor released" and other information messages from arduino via serial, the problem is that when i send messages to the arduino, arduino receives them but the commands don't work properly.
Maybe the server doesn't recognize them in this way or am i missing something?
Thank you very much!
I'll copy here my basic max patch :
