Hello,

I have this plotter. What is the wiring diagram to connect the Arduino to the plotter?

Also what should the voltage knobs be set at. I can't find a manual for this so I'm not sure what they do.

Hi, I have successfully been able to control the X and Y position of this plotter via an ESP32. I'm still stuck on how you wired up to control the pen down relay. Do you know how you wired it up?
