Struggling with start.gcode and end.gcode

Recommended Posts

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
