Skin is a script to smooth the surface skin of an object by replacing the perimeter surface with a surface printed at half the carve
height, and replacing the top infill with half width offset infill. It was made with help from James Blackwell.
Skin gives the impression that the object was carved at a much thinner height giving a high-quality finish, but still prints in a relatively short time. The latest process has some similarities with a description at:
Bookend / Preface
The start and end alterations files are now added by bookend, instead of preface. Bookend is called just before export which means that the start and end commands will no longer be modified by any of the other tools. If you are using start and end files, you will have to move their name settings from preface to bookend.
Clairvoyance is an analyze plugin to open the gcode file with an outside program.
If the 'Gcode Program' is set to webbrowser, the gcode file will be sent to the default browser to be opened. If the 'Gcode Program' is set to a program name, the gcode file will be sent to that program to be opened. A good gcode viewer is Pleasant3D, at:
The 'Orbital Outset' feature has been added to cool.
When the orbit cool type is selected, the orbits will be outset around the largest island by 'Orbital Outset' millimeters. If 'Orbital Outset' is negative, the orbits will be inset instead.
The 'Retract Within Island' feature has been added to dimension, the default is off.
When selected, retraction will work even when the next thread is within the same island. If it is not selected, retraction will only work when crossing a boundary.
Note, in a recent version of skeinforge this was called Retract When Crossing Boundary or something, with the opposite value of 'Retract Within Island'. So if you're using Dimension, you must set 'Retract Within Island', even if you want the default. Otherwise because dimension would read the profile, it would be set on.
Faster than Light
If neutrinos really can travel faster than the speed of light through the earth, this may be because of the Scharnhorst effect in a solid.
The hypothetical Scharnhorst effect is extremely tiny between two parallel plates. If the plates are closer together, the effect increases. In a solid, it is as if the plates were touching, so the effect is greater still. This effect is unoticeable with light because the electromagnetic index of refraction swamps the Scharnhorst effect. However, neutrinos are not slowed by the electromagnetic index of refraction, so the Scharnhorst effect in a solid for neutrinos is noticeable and could boost their speed slightly above c.
Limit / Speed
The 'Maximum Z Feed Rate' has been moved from limit to speed. If you are using limit, you will have to move the 'Maximum Z Feed Rate' to speed.
The 'Maximum Z Feed Rate' now also defines the speed of a vertical hop, like the infill hop in skin.
The 'Reverse Sequence every Odd Layer' option has been added to multiply. Multiply has always reversed the sequence on every odd layer so that the tool would travel less. The problem is that the builds would be made with different amount of time to cool, so some would be too hot and some too cold, which is why the default is off. With the option off, the sequence is the same on every layer.
Printrun / Pronterface
Printrun consists of printcore, pronsole and pronterface, and a small collection of helpful scripts. It is pure Python 3d printing host software:
The contributors page is at:
* printcore.py is a library that makes writing reprap hosts easy
* pronsole.py is an interactive command-line host software with tabcompletion goodness
* pronterface.py is a graphical host software with the same functionality as pronsole
The convex feature has been added to skirt, the default is on.
When selected, the skirt will be convex, going around the model with only convex angles. If convex is not selected, the skirt will hug the model, going into every nook and cranny.
The leading developers of Sprinter are currently Kliment and caru, though many others contribute with their patches:
This is a firmware for RAMPS and other reprap single-processor electronics setups. It supports printing from SD card, active heatbed control, and ATmega internal pullups.
Synopsis & Export
Synopsis is an analyze plugin to export the profile from a skeinforge gcode file as a csv or zip file. It is based on Gary Hodgson's code:
The related functions to add extensions to the file name are in export and follow below.
When 'Add Descriptive Extension' is selected, key profile values will be added as an extension to the gcode file. For example:
When 'Add Profile Extension' is selected, the current profile will be added to the file extension. For example:
When 'Add Timestamp Extension' is selected, the current date and time is added as an extension in format YYYYmmdd_HHMMSS (so it is sortable if one has many files). For example:
Version and Search
The version information has been moved from the main panel to the help panel.
The search buttons have been removed from the main panel, but are still on the help panel.
