 +====== 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
 +
