# Klipper # Start and End G-code The following snippets are used to make the start and end GCODE independent of the slicer used. ## Start Print The start print macro will first warm the bed and then perform an auto bed level while the hotend is warmed to a temperature of 160. This should be a safe enough temperature that the filament is close to operating temperature without becoming soft enough that it begins to flow out of the nozzle. As soon as the ABL is completed the hotend is set to its operating temperature, and then a purge line is done down the left side of the bed. ```gcode [gcode_macro START_PRINT] default_parameter_BED_TEMP: 60 default_parameter_EXTRUDER_TEMP: 190 gcode: M140 S{BED_TEMP} # Set Heat Bed temperature M190 S{BED_TEMP} # Wait for Heat Bed temperature M104 S160 # Start warming extruder to 160 G29 # Auto bed-level (BL-Touch) G92 E0 # Reset Extruder M104 S{EXTRUDER_TEMP} # Set Extruder temperature G1 X0.1 Y20 Z0.3 F5000.0 # Move to start position M109 S{EXTRUDER_TEMP} # Wait for Extruder temperature G1 X0.1 Y200.0 Z0.3 F1500.0 E15 # Draw the line G92 E0 # Reset Extruder G1 Z2.0 F3000 # Move Z Axis up little to prevent scratching of Heat Bed G1 X5 Y200.0 Z0.3 F5000.0 ; Move over to prevent blob squish ``` ##### Calling the start macro in SuperSlicer, PrusaSlicer etc (2.6+): 1. Printer Settings -> Custom G-code -> Start G-code 2. Replace "Start G-code" with: ```gcode START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP={first_layer_temperature[initial_extruder]} ``` ##### Calling the start macro in SuperSlicer, PrusaSlicer etc (Pre 2.6): 1. Printer Settings -> Custom G-code -> Start G-code 2. Replace "Start G-code" with: ```gcode START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP={first_layer_temperature[initial_extruder]+extruder_temperature_offset[initial_extruder]} ``` ##### Calling the start macro in Cura 1. Preferences -> Configure Cura 2. Printers -> Select Printer -> Machine Settings 3. Replace "Start G-code" with: ```gcode START_PRINT BED_TEMP={material_bed_temperature} EXTRUDER_TEMP={material_print_temperature} ``` ## End Print The end print macro will do the standard routing of moving the nozzle out of the way, presenting the print, and turning off the fan, hotend, bed and stepper motors. ```gcode [gcode_macro END_PRINT] gcode: G91 #Relative positioning G1 E-2 F2700 #Retract a bit G1 E-2 Z0.2 F2400 #Retract and raise Z G1 X5 Y5 F3000 #Wipe out G1 Z10 #Raise Z more G90 #Absolute positionning G1 X0 Y{235} #Present print M106 S0 #Turn-off fan M104 S0 #Turn-off hotend M140 S0 #Turn-off bed M84 X Y E #Disable all steppers but Z ``` ##### Calling the end macro in SuperSlicer, PrusaSlicer etc: 1. Printer Settings -> Custom G-code -> End G-code 2. Replace "End G-code" with: ```gcode END_PRINT ``` ##### Calling the end macro in Cura 1. Preferences -> Configure Cura 2. Printers -> Select Printer -> Machine Settings 3. Replace "End G-code" with: ```gcode END_PRINT ``` # Filament MVS Values The following are MVS values calculated using the method described by [Muppet Labs](http://projects.ttlexceeded.com/3dprinting_techniques_calibrating_volumetric_rate.html#test-procedure). The value in the MVS column is the raw MVS, and should be reduced by about ~0.5 mm3/s.
