How to reset start/end gcode ?

Recommended Posts

Reinstalling Cura is one Solution.

Or try in Cura: File > Reset Profile to Default

Or Use the following:

;Start GCode Cura 14.07

;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 S75 ;{print_bed_temperature}

M109 S220 ;{print_temperature}

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M907 E1000 ;set extruder current to normal state

;only needed for Trinamic-Stepper

;not needed for UM2-Original

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...

;END GCode Cura 14.07

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}

Just because I had a nightmare trying to restore mine even after reinstalling these might help someone:

 

Cura 14.09 - Original Ultimaker with Official Heated Bed Kit

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 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...

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}

I have had this too, tinkering with the headers and then not knowing if i have broken something. A "reset to defaults" button for each script would be cool. Once you have edited it, unless you save it away its gone, and even if you reinstall it picks up your old preffernces file with the edits in it.

For future reference, if you rename/remove current_profile.ini in the Cura directory under the Cura installation directory, Cura will regenerate it with the original start/end gcode.

On my system. this file is:

C:Program Files (x86)Cura_14.07Curacurrent_profile.ini

NOTE THAT THIS RESETS ALL YOUR SETTINGS TOO.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
