Simplify3d Starting Gcode

[N5QM]

All,

I need some help with starting gcode for Simplify3D, can you share what you use please?

There's also help with end g-code in http://3dprintboard.com/showthread.p...7-Ending-Gcode

Here is the starting gcode script I use with S3D. Note that I don't have ABL, and my home is at the front-left corner of the printer. I split up the homing process to first move the nozzle to the front left, then I prime the extruder so I can wipe it manually, and then I home Z.

; Simplify3D will already have printer at temperature by this point
M107            ; start with print cooling fan off
G91                 ; relative positioning
G1 Z10 F120   ; raise up before homing to clear clips and prepare for wiping away priming
G28 X0 Y0       ; home X and Y
G1 E8 F180     ; extrude 8mm at 3mm/sec to prime
G1 E-2.5 F900 ;retract 2.5mm at 15mm/sec
G92 E0            ; reset extruded length
G28 Z0           ; home Z
G90                 ; absolute positioning
M82                 ; extruder to absolute mode
M117 Printing...

FOLLOWUP COMMENT: The 3mm/Sec extrusion rate is OK for 1.75mm filament in a hexagon hot end with a 0.40mm nozzle. For 3mm filament, you might get by for this short of an extrusion at 3mm/sec but in general, IMO 1 to 1.5mm/sec would be more appropriate.
