Sfact
SFACT is a simplified version of Skeinforge with some enhancements and some unnecessary plugins deleted. It has correct default values and does not mess up your current SF install as it stores its settings in its own .sfact folder located in the Skeinforge folder. You can get it at: https://github.com/ahmetcemturan/skeinforge
The settings I am not mentioning here you can leave as defaults as they probably have no effect on print quality... (or are obvious enought about what they mean...)
This version of Skeinforge is for stepper extruders only....
In general all default values are now chosen for good prints with 3mm filament and 0.5 nozzle (assuming that this is th emainstream). Even If not, settings are now very easy: Bottom: You don't have to touch it... You can enter a NEGATİVE value in additional height if your nozzle is hovering slightly above the printbed when zeroed.
Carve: THE MOST IMPORTANT DECISION You make... Decide your layer height( for Z resolution) Decide your extrusion width (for XY-sharpness). (Imagine to write small letters with a thick marker) In SFACT it is entered in mm as you probably do not design an object like : lets make the wall thickness 3 times the bottom thickness or so... It will not change when you change layer height.
Important is here that your width should be at least the same or higher than the layer height. Also:
0.8 x D^2 <= w x h <= 2 x D^2
where D=nozzle diameter, w= extrusion width, h= layer height other wise you wil squirt around or drip extrusion uncontrolled.
Infill in direction of bridges: leave it on when you are printing a technical part where you have flat bridges.. Turn off if you are printing organic shapes with lots of half and angled overhangs.. Other wise you will end up with many unnecessarily 100% filled layers.
Clip: Clip over perimeter width (ratio): set it to
0.77 * extrusion width
as a start. If you get gaps where the perimeter line start and end join decrease it, if it forms a bulge, increase it.
Comb: When your retractin is not working well eneough you can make the extruder go detours around "loops (empty areas)" of your part.
Cool: Dont use it...if possible... use a fan instead.
Dimension: Must enable this for stepper extrusion to work !!! Watch your extruder and set retract speed to the fastest it can handle safely without stripping filament, skipping steps etc.
Measure your filament and enter here. Later you can use the packing density setting to increase or decrease overall flow (smaller = more flow..)
The other settings you can leave at default..
Fill: Infill width over thickness ratio does not exist in that form anymore... Now its just a scaler that defaults to one. What it does is it ONLY moves the fill lines together (<1) or further apart (>1). And you dont need to change it everytime.
Infill perimeter overlap: you should can set to the same as clip over perimeter width. Here higher value gives you more overlap.
Multiply: Activate multiply, set rows and columns to 1 each, set x and y center to 100 each. This will center the object on the board.
Speed: Set here your feedrates for the print.. values up to 70mm/s should give you decent prints. A good method is to set the feedrate (the value the fill is printed) relatively high and then to reduce the speed for the perimeter (the shell that we see and perceive as nice).. I normally use half speed of the fill..
Use same values for feedrate and floowrate as long as you really know what you are doing... (like feed= 70 / flow =70 and perim feed = 0.5 / perim flow = 0.5)
Travel feedrate should be as high as possible without skipping steps, shaking your printer too much and stressing your hardware.. (150 seems a nice value...with sprinter and accleration of course...)
