Jogging the mill is a pain in the ass. One of the most helpful GCode commands you can use is "go to coordinate". To go to an X coordinate "zero" one would use "g0 x0", similarly to go to y0 one would use "g0 y0". This is especially helpful for moving the tooling out of the way to add a new piece to be milled or to make an adjustment. Subsequently, the tooling can be reset with "g0 x0" "g0 y0" "g0 z0"
Redbeard made some changes to the config file including resetting the initial home positions to "0 0 0 0" so that when the application starts up, it will leave the tool exactly where it is placed. While this isn't the behaviour we want long term, it's perfect for our current lack of limit switches. Additionally, the directive "no_force_homing=1" was added to get rid of pesky error messages (again, since we don't have limit switches for homing the device.)
