 +====== Skeinforge Settings for our PrusaMendel ======
 +===== Config file on internet =====
 +Working configuration is stored at https://github.com/AxTheB/skeinconf
 +
 +===== Hardware that we have =====
 +We have RAMPS board, wades extruder and use 1.8deg steppers with *8 multistepping. ATM we can do moves with feedrate 4800 in X direction and 5500 in Y direction smoothly.
 +We have Sprinter firmware, with e_steps_per_unit set to mm of feedstock.
 +
 +===== Custom gcode files =====
 +.skeinforge/alterations/homing.gcode (this one is run every layer. Read temperature)
 +<code>M105</code>
 +
 +.skeinforge/alterations/start.gcode (this one is put before the first line of generated file. Sets metric, absolute positioning then homes all axis)
 +<code>G21
 +G90
 +G1 X-250 Y-250 F4500
 +G1 X-250 F4500
 +G92 X0
 +G1 X2 F800
 +G1 X-10 F800
 +G92 X0
 +G1 Y-250 F4500
 +G92 Y0
 +G1 Y2 F800
 +G1 Y-10 F800
 +G92 Y0
 +G1 Z-250 F60
 +G92 Z0
 +G1 Z1 F10
 +G1 Z-10 F10
 +G92 Z0</code>
 +
 +.skeinforge/alterations/end.gcode (this is appended to end of generated file. Moves the printed object to front then homes Z, as homed Z axis oozes less)
 +
 +<code>G92 Z0
 +G1 Z2 F30
 +G1 X0 Y200 F4500
 +G1 Z-250 F30
 +G92 Z0</code>
 +
 +===== SF =====
 +Settings for plugins, as they appear in the interface. SF40, everything is in Craft tab. Settings are for PLA
 +
 +==== Bottom ====
 +When Z axis homes its touching the plate to prevent oozing, so we have ''Additional Height over Layer Thickness (ratio)'' set to 0.8
 +
 +==== Carve ====
 +Left to defaults
 +
 +==== Chamber ====
 +Activated, ''Bed Temperature'' set to 45
 +
 +==== Clip ====
 +Active with defaults
 +
 +==== Comb ====
 +Inactive
 +
 +==== Cool ====
 +Active, ''Minimum Layer Time (seconds)'' set to 20. ''Method'' set to ''Slowdown''
 +
 +<del>This one is still problematic, as less means objects will deform, but after 10 seconds of circling the extruder oozes a bit.</del> Probably solved by Slowdown instead of circling.
 +
 +==== Dimension ====
 +Activated. ''Filament diameter (mm)'' is set to measured 2.80 and ''Filament packing density (ratio)'' to 1
 +
 +''Retraction Distance (milimeters)'' is set to 1.5 which gets very good results, except when cool plugin is circling 
 +
 +==== Export ====
 +Deactivated ''Add Export Suffix''
 +
 +==== Fill ====
 +Active, with ''Infill solidity'' set to 0.23 (its prettier than 0.20 and we have translucent objects)
 +
 +==== Fillet ====
 +Inactive
 +
 +==== Home ====
 +Activated, homing.gcode is used to read temperatue
 +
 +==== Hop ====
 +Inactive
 +
 +==== Inset ====
 +Active, at defaults
 +
 +==== Jitter ====
 +Inactive
 +
 +==== Lash ====
 +Inactive
 +
 +==== Limit ====
 +Active, ''Maximum initial feed rate (mm/s)'' set to half of feedrate, ''Maximum Z Feed Rate (mm/s)'' set to 1.5
 +
 +Faster Z feed rate was giving funny results, as all objects were shrunk to 2/3 of expected size. Not sure about maximum initital feed rate setting. 
 +
 +==== Multiply ====
 +Activated, ''Center X (mm)'' and ''Center X (mm)'' set to 90
 +
 +This one moves objects to center of build plate. Quite important.
 +
 +==== Oozebane ====
 +Inactive
 +
 +==== Preface ====
 +At default values
 +
 +==== Raft ====
 +Active, with ''Base layers (integer)'' and ''Interface layers (integer)'' set to 0 - objects are good enough when printed directly on heatbed. ''Object First layer'' infill multiplier both set to 0.7, perimeter multiplier both set to 0.5
 +
 +Rest at defaults.
 +
 +==== Scale ====
 +Inactive
 +
 +==== Skirt ====
 +Active, with ''Gap over Perimeter Width (ratio)'' 3.0, rest at default. With skeinforge from git I have activated ''Convex''.
 +
 +==== Speed ====
 +Active, with ''Feed Rate (mm/s)'' and ''Flow Rate Setting (float)'' both set to 45, ''Travel Feed Rate (mm/s)'' is 55 and in ''- Perimeter -'' both values at 0.7
 +
 +This one slows down when printing outer layer, making prints prettier.
 +
 +==== Splodge ====
 +Inactive
 +
 +==== Stretch ====
 +Inactive
 +
 +==== Temperature ====
 +Activated, but all temps set to 195
 +
 +==== Tower, Unpause, Widen, Wipe ====
 +Inactive
 +
