We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I just got an AxiDraw pen plotter and it's too much fun.
I wrote a little wrapper for CNC Server and wanted to share it + my example in case anyone else has one and wants to play around with it in Processing.
Processing code here: https://github.com/koblin/AxiDrawProcessing
This also includes a simple example of HTTPClient for PUT and DELETE calls (something I was surprised isn't already built out in Processing... though maybe I missed something obvious).
