    Hi All,
    I'm using openbuilds control for a long running relief carving that I left running over night (I have fire and video surveillance). When I checked on it in the morning the router was running but no commands were being sent. After investigation I saw that the com port was closed and I was not able to reconnect to the cnc. I suspect the cause was my mac going to sleep. I disabled sleep and power nap, but it still slept. Has anyone else experienced this? I'm wondering if the command line tool "caffeinate", or the app "amphetamine" could prevent this. Thanks in advance for any help/advice.

    Cheers,
    Joey

    System Preferences-> Battery(laptop)/Energy saver(desktop) then uncheck prevent your Mac from auto sleeping when display is off

    If it's a laptop select power adapter on the left

    Hope that helps

    I use the app caffeine for this.
    Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers.​
