Hello,
How can I make the printer extrude a little bit of filament (about 3cm ~ 5cm) off the platform when it is done printing?
My starting script is:
M73 P0 ; enable build progress
G162 X Y F3000 ; home XY maximum
G161 Z F1200 ; home Z minimum
G92 Z-5 ; set Z to -5
G1 Z0 ; move Z to 0
G161 Z F100 ; home Z slowly
M132 X Y Z A B ; recall home offsets
M135 T0 ; load right extruder offsets
G1 X150 Y-70 Z30 F9000 ; move to wait position right hand side of the table
G130 X20 Y20 Z20 A20 B20 ; lower stepper Vrefs while heating
M126 S[fan_speed_pwm]
M140 S[bed0_temperature] T0
M134 T0 ; stabilize bed temperature
M104 S[extruder1_temperature] T1
M133 T1 ; stabilize left extruder temperature
G130 X127 Y127 Z40 A127 B127 ; default stepper Vrefs
G92 A0 B0 ; zero extruders
G1 Z0.3 ; position nozzle
M135 T1 ; left tool
G1 X-90 Y-70 E25 F1200 ; prime nozzle
G1 X-100 Y-70 F180 ; Wait for ooze
G1 X-110 Y-70 F5000 ; Fast wipe
G1 Z0.5 F100 ; Lift
G92 A0 B0 ; zero extruders
M73 P1 ; @body (notify GPX body has started)
My ending script is:
M73 P100 ; end build progress
G1 Z150 F1000 ; send Z axis to bottom of machine
M140 S0 T0 ; cool down HBP
M104 S0 T0 ; cool down right extruder
M104 S0 T1 ; cool down left extruder
M127 ; stop blower fan
G162 X Y F3000 ; home XY maximum
M18 ; disable stepper
M72 P1 ; play Ta-Da song
Thank you!

Re: How to make printer extrude a little after print is done
Add "G1 E##" where ## is the millimeters you want to extrude to the beginning of your end script. Probably after the first line so the extrusion happens at the right hotend temp.

Re: How to make printer extrude a little after print is done
Thank you for your answer! But what if I want to extrude off the platform? Should I write like this? What's a typical load filament speed? I set it to F1200 but I wonder if that is too slow?KC_703 wrote:Add "G1 E##" where ## is the millimeters you want to extrude to the beginning of your end script.

G1 X130 X-70 E50 F1200 ; prime nozzle <------------- Does this move the head first then extrude, or extrude while moving?
