I want over 200mm automatic shutdown height if I print some tall/looong jobs..
Extruder Shutdown height is about 227mm.

I also litlebit modified switch_pusher with tinkercad to stronger than orginal..
I use hotglue on switch_holder.

copy paste these start/end-.gcodes to your slicer. (I use cura)
(You have to find the right movements on :G1 Z229 F3600 ; move 229mm to the top G1 X198 F3600 ; move 198mm to the right)

START.GCODE:

;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time: {print_time}
;Filament used: {filament_amount}m {filament_weight}g
;Filament cost: {filament_cost}
;M190 S{print_bed_temperature} ;Uncomment to add your own bed temperature line
;M109 S{print_temperature} ;Uncomment to add your own temperature line
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 ;home
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F9000
M117 Printing...
