Hello
First of all I must tell you that I am a newcomer here and I apologize in advance for my bad English.
I have one problem with my project. I am working on a plotter, which is based on CNC. For controlling i'm using Mach3, and i wanted to jog my stepper motors via buttons. But when i wired my parallel port from PC and output signal from Arduino with Step pin from stepper motor driver, the signal from Mach3, stoped working.But when i disconnect the arduino output signal, the signal from mach3 started working again. Can anyone tell me why does it work like that?
