To upgrade from master or edge to the new motion control firmware
-----------------------------------------------------------------

The following changes must be made to your config

1. alpha_max, beta_max, gamma_max must be correctly defined for homing to work properly even when homing to min
   they control the maximum distance the axis will move before it gives up finding the home switch.

2. it is best to start from a fresh config
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)

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.
   the homing_order setting still works the same way as before.

The following changes must be made to your hardware
---------------------------------------------------

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.
