I bought my printer 2 months ago, a Flashforge Creator Pro, and started using Simplify3D without any issues, but I did a firmware update on my printer to Sailfish 7.8 and after that this issue appeared. I can see the solution on the last page stating the following:
Starting Script Before:
G28 ; home all axes
G1 Z0.2 F1200 ; raise nozzle
G92 E0 ; reset extrusion distance
G1 X100 Y0 E12 F600 ; purge nozzle
Starting Script After:
M106 S0 ; turn off cooling fan
G28 ; home all axes
G1 Z0.2 F1200 ; raise nozzle
G92 E0 ; reset extrusion distance
G1 X100 Y0 E12 F600 ; purge nozzle
M106 S;[fan_speed_pwm] ; set fan to variable PWM value
However it seems my knowledge or lack of intelligence is simply not there to figure out where I should put those "Starting Script After" commands in on my current preset Starting Script of the Flashforge Creator Pro which has the following:
; **** Replicator 1 dual start.gcode ****
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 X-110 Y-70 Z30 F9000 ; move to wait position left 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 Z0.4 ; position nozzle
M135 T1 ; left tool
G1 X-140 Y-70 F9000 ; reposition nozzle
G1 X-100 Y-70 E25 F300 ; purge nozzle
G1 X-110 Y-70 Z0.15 F1200 ; slow wipe
G1 X-100 Y-70 Z0.5 F1200 ; lift
G92 A0 B0 ; zero extruders
M73 P1 ;@body (notify GPX body has started)
; **** end of start.gcode ****
I assume M126 S[fan_speed_pwm] needs to be removed and somewhere along the lines the aforementioned commands needs to be put, but can those lines just be put anywhere? I guess the printer reads the script from top to bottom so something is telling me I can't just put it where ever I choose x)
For your Creator Pro I would not modify the start script if it was fine. Go to the cooling tab in S3D and find the fan overrides section and uncheck "Increase fan spped for layers under ...". The Creator Pro fan is an on/off fan anyway so it has no speed control and this section doesn't apply to it.
