Programming Feedrates

G36 is the default mode and is established at power up, E--STOP reset, and
end-of-program (M02, M30, or M99). The recommended method of
programming G36 and G36.1 is to program a relatively long entry and exit
move into/out of the mode.
The entry move should be a long move in the general direction of the
first short block, and at the same feedrate as the first short block. This
entry move should be long enough for the axes to reach programmed
speed. Program the G36.1 code in this entry block.
The exit move should be a long move in the general direction of the last
short block, and at the same feedrate as the last short block. This exit
move should be long enough for the axes to decelerate properly without
overshooting its endpoint. Program the G36 code in this exit block.
The following example shows the recommended entry and exit moves for
short block mode.
