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)

M105

.skeinforge/alterations/start.gcode (this one is put before the first line of generated file. Sets metric, absolute positioning then homes all axis)

.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)

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

This one is still problematic, as less means objects will deform, but after 10 seconds of circling the extruder oozes a bit. 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
