[Emc-users] Machine POWER (ENABLE) button.

This is a question about how most Linux Systems use the ENABLE and ESTOP signals. For a LinuxCNC system running on a PC, the screen is pretty well identical to the MachineKit screen on a Beaglebone. On the top left is the X button for ESTOP and beside that the POWER (ENABLE) button which

Hi Gene, My use case has nothing to do with machining. I'm using a cnc mill as a precise robot. For the benefit of an eventual future user with the same use case, imagine you have a camera with a signal that triggers at the begining of each capture, and that you're capturing during CNC motion.

[Emc-users] index-enable pin

Hi all, I'm trying to implement a somewhat exotic behavior with EMC2. I have a servo setup with two Pico Systems univpwm boards. I have spare encoder channels I want to use to precisely checkpoint the position of a channel when an external signal is triggered. So I have, concretely, encoder.03's
