Check And G28 problem

[ykilic2776]

If $C check mode is left on, when arduino serial port is opened and closed, check mode stays on, this is a problem, if $H is set to home location, G28 code moves to $130=20 $131=20 $132=20 X-20Y-20Z-20 and machine it goes to this coordinate It is more logical to have G28= X0Y0Z0 after $H.
