First layer lump of filament

[Kevink]

Just installed the software form my flash forge creator dual sailfish firmware.On a windows x64 system.

When the extruder and the platform are heated up and ready for printing, the extruder squeezes out some filament on the platform without moving.
This results in a lump of melted plastic witch the extruder will drag around during printing, and worst case will get stuck in the print.

Does anyone know a setting somewhere ?

Sounds like the purge and wipe set of commands in the starting script, which can be found under starting g-code in the scripts tab. I don't have a flashforge creator, but i just checked the gcode in the script (at least what appears in my creator dual profile) and it seems to be right?

Thanks for the reply.

Here is the start Gcode concerning a file causing problems:
(it happens with all the prints)

; **** Replicator 1 dual start.gcode ****
M73 P0 ; enable build progress
G162 X Y F3000 ; home XY maximum
G161 Z F1200 ; home Z minimum

; **** end of start.gcode ****

I don't know much about geode, but I compared it with a replicating geode file, and it looks like what is missing is something like this:
G1 E4 F300 (Extrude 4mm of filament)
Just having a look at the geode of this post, and noticed
G1 E25 F300 ; purge nozzle
But the extruder doesn't move 25mm ?

Thanks, Kevin.
