Robot: Arduino uno with CNC V3 shield (com1) and A4988 stepper drive chips for x and y. 9g servo for z.
Drawing area: A4 paper
Operating system: Windows 10
Goal: control CNC plotter with mouse in processing, I want to be able to draw with my mouse. So far I have only found cnc software that works with gamepads. I want it to work with exact coordinates (if I for example I start drawing in say x50y50 in processing, it corresponds to x50y50 on the paper with the arduino). This is important because there might be a time lag, since the mouse in processing is likely faster than the arduino controlled cnc and I want it to work in real time.
I found this thread with code that didn't work (which was for a mac computer as well): processing example controlling stepper x y - Interfacing w/ Software on the Computer - Arduino Forum
I have never paid for gigs on here before but if paypal fnf payment works for you then that would be great.
