Customized BLTouch addon for the Cobblebot Hotend Mount by irononreverse: http://www.thingiverse.com/thing:932645 V3 has improved positioning. Offset for the BLTouch to the hotend is found at the bottom of this summary. You can see this youtube video to see it in action: https://youtu.be/kh8dfugXY18 These are my experiences with configuring my BLTouch for use on my Cobblebot using Marlin 1.1.0-RC. It seems like there's a lack of information about this so I'm hoping this will be helpful to someone. My configuration is currently working but it's still a work in progress and may change.
