So far so good! I built it to be able to adjust to any size, and am hoping to do some full wall plots soon.
Polargraph Drawing Machine
I'm having problems with rendering images, I can't seems to make any of the "squiggles", only empty lines. I found this thread: http://www.polargraph.co.uk/forum/polargraphs-group2/troubleshooting-forum5/up-and-running-but-no-image-yet-thread248/ which seems to be the same problem I am having but I didn't see how/if it got resolved. Vector drawing worked just fine for me. Any ideas or troubleshooting tips? I've tried quite a few different grid size and sample area changes. Thanks again!
Thanks for the response! That's what I was worried about. I think I'll try to print a tensioner arm that holds a bearing to the pulley so it can't skip. I'll post some pictures of the setup if it works.
What is the solve if you have a drawing area larger than you have space for the counterweight on the string? For example when the carraige is in one of the upper corners the counterweight is touching the ground, and no longer providing weight to keep the belt from skipping,
