"perfect" start.gcode & end.gcode for Cura 15.04.2 (Mac) for Octoprint

[frederiekpascal 186]

I've been reading this board and several threads about octoprint and reprap.

It looks like the default end and start code is not the best to use.

Currently it is :

start.gcode :

 

G28G1 X110 Y45 F3000 ; bring extruder to the frontG92 E0 ; zero the extruded lengthG1 Z30 ; lowerG1 E50 F225 ; purge nozzle with 50mm of filamentG1 X80 Y60 F3000 ; move aside of the puddle of primed plasticG92 E0 ; zero the extruded length again

 

end.gcode :

 

G28M104 S0 ; turn off heatersM140 S0 ; turn off bedM84 ; disable motors

 

But that doesn't seem to be the perfect codes to use with Octoprint?

Anybody who can help me out with tweaking this code to use with my Ultimaker2?

Thanks in advance

Ha I recognise that code. Its my simplify3d start code. Easy to recognise as it starts in the front-middle and not the left-front. You can change the xy easy to left front again. I've not used octoprint but it's on my todo list. .. i'll see if I can have a look soon.

ow OK, my bad :-)

The default start.gcode is :

;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 X0 Y0  ;move X/Y to min endstops
G28 Z0     ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0                  ;zero the extruded length
G1 F200 E3              ;extrude 3mm of feed stock
G92 E0                  ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen
M117 Printing...

default end.gcode :

;End GCode
M104 S0                     ;extruder heater off
M140 S0                     ;heated bed heater off (if you have it)
G91                                    ;relative positioning
G1 E-1 F300                            ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more
G28 X0 Y0                              ;move X/Y to min endstops, so the head is out of the way
M84                         ;steppers off
G90                         ;absolute positioning
;{profile_string}

which one should I use? Or do I need adjustments to any of the codes?

Not perfect but it's mine
