Struggling with start.gcode and end.gcode

Hi guys,

While trying to understand the GCodes and SF a lot better I ended up in fine-tuning a start.gcode and end.gcode which is used by SF (Preface).

Last friday Siert wrote a simple but effective start.gcode on an Ultimaker Workshop day which he sent to me. I tried to replace the standard start.gcode with Siert's version but I can't find the right path for the code.

I have two questions about this:

1) How do I know which start.gcode SF uses?

2) I can imagine some people wrote there own start and end files. I'm really interested in those codes! ;-)

Thanks,

Michael

    Hi,

    i'm no expert but as far as i know:

    1) How do I know which start.gcode SF uses?

    On my system (Mac OS) in the ReplicatorG25 directory, each skeinforge engine has its own directory with /prefs in witch different (gcode generator) profiles are stored in separate directories.

    In each profile directory is a subdirectory called: alterations.

    In directory alterations, the start.gcode and end.gcode are stored.

    /ReplicatorG25/skein_engines/skeinforge-35/skeinforge_application/prefs/SF35-ULTIMAKER - Quality print/alterations/start.gcode

    For ReplicatorG24 it's different; its a file in a hidden directory in the root:

    /Users/Username/.replicatorg/sf_31_profiles/Dupli ULTIMAKER - ABS - Q/alterations

    So, depending on witch RepG, SF and profile you use a different stored start.gcode is used.

    2) I can imagine some people wrote there own start and end files. I'm really interested in those codes!

    A code i use:

    G21 (Metric: The unit is a millimeter)

    G90 (Absolute Positioning)

    G28 Z0 ;physical home Z

    G92 X0 Y0 Z0 ;This is zero

    G91

    G1 Z25.0 F400 ;Move down platform 25mm with speed 400

    G92 E0 (zero the extruded length)

    G1 F1000 E260 ;Extrude material

    G1 F3000 E-20 ;A little pullback of fillament

    G92 E0 (zero the extruded length)

    M1 (Clean the nozzle and press YES to continue...)

    G1 Z-24.0 F400 ;Move up platform 24mm with speed 400

    G1 Z-1.0 F100 ;Move up platform 1mm with speed 100

    G90

    G92 E0

    G1 E0.00

    M104 S220.00 ;Temperature set

    I don't know if it's perfect (especially regarding the extrusion length) but it works fine for me.

    Greetz,

    Berend

    Hi Berend,

    thanks for the reply. One thing I noticed: Do you preheat manually before building the code? I can't find a code in which you heaten up the extruder before this line:

    "G1 F1000 E260 ;Extrude material"

    Or am I missing something?
