Re: Skeinforge contributions - 15 years ago
Hi Erik, Thanks for writing your 3D-to-5D script and for offering to test new settings. I've added a link to your script from the first post. Over time I'll port features from your script to skeinforge. Cheers, Enriqueby Enrique - RepRap Host
Sawtooth interval position check - 15 years ago
Just had an idea that we could use a sawtooth interval strip to give frequent position checks with one of the optoswitches. The other optoswitch would be used for both endstops. The sawtooth interval strip would look like the ascii diagram below. The 'O' is for the opaque part of the strip and the 'T' for the transparent part.

Re: Larger Reprap? - 15 years ago
Groygan, I completely agree with you. You bring up the excellent point that sag is a big problem with big machines and there is a quick to implement design change that can fix it for at least the next factor of two bigger. An alternate design change would be to replace the relatively thin solid rod with wide tube. This would not be quite as stiff as box extrusion, but it would be quicker to iby Enrique - General

Re: Skeinforge settings - 15 years ago
unfold, You can click 'Add Profile' in the extrusion dialog, the new profile will be a copy of the old selected profile. For example, in the extrusion dialog, select ABS, then type 'ABS_UserSettings' and click 'Add Profile'. This will create a copy of the 'ABS' settings called 'ABS_UserSettings' and you can change that without affecting the old 'ABS' settings. arhimed, Thanks for the settinby Enrique - Skeinforge

Skeinforge settings - 15 years ago
This is a thread for people to post your skeinforge settings and your skeinforge scripts. Every once in a while I will gather the posted settings and put them into the profiles folder in skeinforge. The best way to post the settings is as an attached zip file. The naming convention of the files should be the name of the machine or developer, then the material or method, then optionally specifiby Enrique - Skeinforge
Re: advice - 15 years ago
The quickest way to start contributing is to write documentation. For example skeinforge needs more documentation and you can help develop it on the wiki at: Once you know the project better, you can try designing stuff and posting it on thingiverse: Once you contribute for a while, you'll get to know people and if you contribute a lot, eventually someone will offer to print parts for you.by Enrique - General
Re: Skeinforge Powwow - 15 years ago
There was a problem with hole insetting with one of the versions of skeinforge, the latest version attached and at: has that bug fixed. However, since it is an in progress version there may be other bugs, so I did not put it into subversion. If someone tells me that it works without new bugs, I'll update subversion.

Re: From Blender to Ponoko - 15 years ago
Grogyan, With the current version of skeinforge, carve just carves the shape, it does not inset it. So you can use a reasonable value for the extrusion width, you don't have to try getting it close to zero. Carve just uses the extrusion width to determine the import radius when spanning gaps of a model with holes. If the model is correct, extrusion width will not be used at all by carve.

Re: Skeinforge Powwow - 15 years ago
In my last post I forgot to mention that cool has been changed. There is now a Minimum Orbital Radius for the orbits, an idea of the Masked Retriever. Also, thanks to Ahahn, if there is a file cool_start.txt, cool will add that to the start of the orbits. After it has added the orbits, it will add the file cool_end.txt if it exists.

Re: Skeinforge Powwow - 15 years ago
The latest skeinforge is attached, in subversion and at: Preface.py has been added. Preface converts the svg slices into gcode extrusion layers, and optionally adds initial gcode commands. It basically does part of what inset.py used to do. By popular demand, there is now a date string in version.txt in skeinforge_utilities in skeinforge_tools. The version date string is added in the conteby Enrique - Skeinforge
Re: possible prize for reprap development - 15 years ago
I also agree with rodzite that specifying a percentage of parts that it can make is going to be problematic and can be gamed. Instead, the mass of vitamins should minimized. This avoids gaming with multifunction parts, or massive parts or lowball parts pricing. Mass can not be gamed in any way. I also agree with Adrian that entries must be developed in public.by Enrique - Kartik M. Gada Humanitarian Innovation Prize
Re: Skeinforge Powwow - 15 years ago
arhimed, the E value in the G1 is the in progress skeinforge support of Adrian's extruder distance, as described at: and in Erik de Bruijn's conversion script page at: The E value can be removed by setting the "Extrusion Distance Format Choice" to "Do Not Add Extrusion Distance".

Tony, Without your zipped preferences I can't be sure, but I think the first line after M103 an acceleration, set half way between the 960 and 2400, is because "Use Intermediate Feedrate in Corners" in fillet is selected. All the code between M103 and M101 is to move the head round features of the object and is because "Activate Comb" in comb is selected. After M101 the deceleration from the fby Enrique - Skeinforge

Re: Skeinforge Powwow - 15 years ago
arhimed, For skeinforge to execute multiple files at once, in polyfile choose "Execute All Unmodified Files in a Directory". While that is chosen, skeinforge will execute all the unmodified files in a directory which the chosen file is in. An unmodified file just means something like Screw.gts, rather than Screw_fill.gcode or Screw_raft.gcode. For changing the PWM number, I do not want to doby Enrique - Skeinforge
Re: behold trouble - 15 years ago
Vik, The error occurred because in the line: G1 F20.0 ;Low speed for Z move skeinforge decoded it, in part, into "Z" and tried to turn the nonexistent part after into a float. It expects lines like: G1 Z1.23 which it would decode, in part, into "Z1.23" and turn that into "1.23". Skeinforge now checks to see if after a character the string is empty.

Re: RepRap on an OLPC - 15 years ago
There is send.py and RepRapArduinoSerialSender.py in the fabricate folder in the miscellaneous folder in skeinforge. I haven't tried them because I don't have a reprap, but apparently they work. I believe they use pyserial, so would probably suffer from pyserial delays or problems.
