I installed PP 2.2.2 this morning and spent a little time exploring. There are a number of new ADMIN commands listed but many do not appear to do anything. For example ADMIN GET_AXIS_BACKLASH is accepted but doesn't show anything on the Status tab. ADMIN MEMORY works as expected. ADMIN MOUSE gives a nice menu to set mouse speed and other goodies. ADMIN BOOTMENU ON briefly enables coolant and then gives the errors in the second screen shot. It seems that a controller reboot is required to again connect to my 770. After the reboot everything appears normal and unchanged.
Has anyone else tried the additions?
