I'm trying to finalize my SmoothStepper install with Mach3 and an "existing" profile. The eStop was working fine but now the physical eStop is works but the software eStop in Mach is not working.

Does anyone have any suggestions on how to fix this?

I'm seeing the following in the History log when starting Mach and hitting the Estop:

Mon - 06:49:09 ---Program Startup
Mon - 06:49:10 ---ReConfiguration Estop.
Mon - 06:49:13 ---Application Watchdog Triggered
Mon - 06:49:32 ---Limit Switch Triggered
Mon - 06:49:35 ---command killed due to buffer error.

Adam,

We'll come to find out I don't have an issue, well besides me. I was remembering incorrectly
how Mach handled an eStop on my machine.

Sorry for the noise.

Adam,

Any luck on the 'Application Watchdog Triggered' error? I'm getting the same message and I'm having random e-stops that need the controller power cycled to reset.

Oscar, go into the SS plug in and set the watchdog timer to 3.1

I've adjusted the watchdog timer and still get the same issue. I can't find any reference anywhere to "Application Watchdog" and what it might mean. A lot pf people report Driver watchdogs but not Application.
