E stop and Mach 3 help needed
« on: November 09, 2009, 03:10:45 PM »
got  a g540 and mach3 hooked up with 3 steppers, Terminal 1,2,3,4 and 10 are grounded.  (simulating home and estop switches)  . Mach 3 is setup and sees the home switches.  ( Port 1, pins 10,11,and 12 )  The problem is with the e stop.  I set up Mach3 ESTOP input to port 1 and pin 15.  Is this correct.  Mach 3 will se the estop but can't reset the g540 unless I use port 0 in Mach 3  ( which dissables it ) .  If i put LOW  true on the ESTOP  input I can get mach3 to clear the red LED on its Diagnostics displat (Emergency LED) .  If I dont use the estop input I can clear the errors and get the G540 to go green ( no fault ) and get motors to run.   I can then pull the estop ground on the G540 and get a fault.  So it works on the G540.  But the question is how do i get an ESTOP error to show up on Mach 3  as an Emergency LED on the daig screen.  Port 1 pin ??. ???

Are you referring to false triggering of the EStop ?
