Added F (probing speed) and T (travel speed) parameters to M558 command Removed M210 command because home feed rates are defined in the homing files Increased UART interrupt priority to avoid dropping characters sent by PanelDue Bug fix: M558 P3 did not leave the Z probe control pin high Bug fix: in version 1.09j only, the move following a G92 E0 command was sometimes executed from an incorrect start point Fixed bugs with reads/writes from/to the SD card that spanned one or more whole sectors Updated to latest Atmel HSMCI driver
