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)
.skeinforge/alterations/start.gcode (this one is put before the first line of generated file. Sets metric, absolute positioning then homes all axis)
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
.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)
G92 Z0 G1 Z2 F30 G1 X0 Y200 F4500 G1 Z-250 F30 G92 Z0
Settings for plugins, as they appear in the interface. SF40, everything is in Craft tab. Settings are for PLA
When Z axis homes its touching the plate to prevent oozing, so we have
Additional Height over Layer Thickness (ratio) set to 0.8
Left to defaults
Bed Temperature set to 45
Active with defaults
Minimum Layer Time (seconds) set to 20.
Method set to
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.
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
Add Export Suffix
Infill solidity set to 0.23 (its prettier than 0.20 and we have translucent objects)
Activated, homing.gcode is used to read temperatue
Active, at defaults
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.
Center X (mm) and
Center X (mm) set to 90
This one moves objects to center of build plate. Quite important.
At default values
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.
Gap over Perimeter Width (ratio) 3.0, rest at default. With skeinforge from git I have activated
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.
Activated, but all temps set to 195
