   1 To upgrade from master or edge to the new motion control firmware
   2 -----------------------------------------------------------------
   3
   4 The following changes must be made to your config
   5
   6 1. alpha_max, beta_max, gamma_max must be correctly defined for homing to work properly even when homing to min
   7    they control the maximum distance the axis will move before it gives up finding the home switch.
   8
   9 2. it is best to start from a fresh config
  10 3. you must delete the config-override (M502) as M203 format has changed (M203 sets cartesian max speeds, M203.1 sets actuator max speeds, no longer uses ABC as these are now reserved for future n-axis)
  11
  12 4. Homing is slightly different, by default it will home X and Y axis at the same time then Z, this can be reversed and have Z home first then X and Y.
  13    the homing_order setting still works the same way as before.

  15 The following changes must be made to your hardware

  18 1. Due to a mistake in the previous versions of the firmware the E direction was reversed, so you must invert your dir pin for your extruders (or reverse the extruder plug) from how they were before.
