also, it will estop when i click the reset button on the screen, but not when i click the stop button. i always thought it did estop when clicking stop, but honestly can not remember for sure. i will run a program this morning and try clicking stop to see if it at least does stop the program. i checked settings in mach, and estop is still enabled??? i noticed there is a jumper wire on the BOB that goes from pin 10 on the input side(estop pin) to the output side, and it has a capacitor inline(green wire about 8" long). could this capacitor have burned out? keeping the controller up and running is like painting a bridge on this thing!!!
