The big red estop on top of the controller box kills ALL power to the box (will not turn of spindle). It’s connected directly to the power supply.
The digital estop on the upper right of the screen is a ‘digital’ estop and will turn everything off and reset all zeros without killing all power.
The stop button will just stop the program. You’ll retain zeros, position, etc when using the stop button.
Good practice is to push the ‘start’ button and watch as the machine starts it’s process. Usually within the first 30 seconds - 1 minute, you’ll know if the cut will be go. We like to keep our finger hovering over the ‘start’ button as it changes to a pause button. If something is wrong, we’ll hit pause. If it’s something we’ll need to restart, we’ll then hit stop. If it’s something we can adjust (clamps, material, dust, etc), we’ll adjust it while it’s paused, then hit the pause button again to resume the cut.
If all &@^( breaks loose, slam that big red button!
