i just purchased digital Rockcliff cnc machine plans over the net and the Mach3  software was included. Iam totaly new at cnc software and working  with it to get to know it, nothing seems to work . its constantly asking for an external Estop on the bottom left hand corner.?
I have no hardware hooked up, and the reset botton is useless?   somebody help me.
also looking to start building a small cnc router and help selecting hardware would be appreciated.

thanks ticoe

Go to the diagnostics tab and see if any inputs (little red lights on the right of the screen) are on.

As you have no hardware hooked up,

Go to,  Config / Ports and Pins / Input Signals and scroll down to Estop and toggle the Active low setting.

After that go to the following link,

Watch at least these videos, "Downloading and Installing", "Hooking up Inputs and Outputs",  "Screens - An Overview" and "Coordinates / Homing"
