Why does it say "External Estop request" when ever I try reset Mach3?

This messages means that the Estop input is active, usually evidenced by the flashing of the Emergency LED on the Diagnostics screen. If a physical Estop button has been wired into the breakout board, verify that the port/pin assignment and Active Low settings are correct. If there is no physical button, set the pin number to 0.
