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

This message 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. Restart Mach3 and test the new setting by pressing the physical EStop button. If there is no physical button, set the pin number to 0.
