Introduction

Many modern sewing machines (including the ones for the home market) can be computer-controlled. Good sewing machines can sew, stitch and quilt. I.e. you get three machines in one. We probably can distinguish between the following kinds of models:

  • computer-controlled (directly from a computer). I imagine that these could exist in industry.
  • computer-controlled (via file upload, i.e. specific firmware in the machine will read a proprietary CNC file and execute it). That's the solution existing in mid and high-end home machines (in the $500 to $10000 range). A good model (like a Swiss Bernina that can both sew and stitch will cost around CHF 3000.-)
  • Computer-powered, i.e. the machine will have more than a single motor and stuff is synchronized with a computer instead of complex mechanics. Typically, low and mid-end home machines.

For the time being, this page will focus on embroidery. See also fab lab, an introduction to end user-created design and fabrication.

In computer-powered or computer-controlled home sewing machines, “the computer directly controls several different motors, which precisely move the needle bar, the tensioning discs, the feed dog and other elements in the machine. [...] The computer drives the motors at just the right speed to move the needle bar up and down and from side to side in a particular stitch pattern. Typically, the computer programs for different stitches are stored in removable memory disks or cartridges. The sewing-machine computer may also hook up to a PC in order to download patterns directly from the Internet. Some electronic sewing machines also have the ability to create complex embroidery patterns. These machines have a motorized work area that holds the fabric in place underneath the needle assembly. They also have a series of sensors that tell the computer how all of the machine components are positioned. [...] The sewer simply loads a pattern from memory or creates an original one, and the computer does almost everything else.” Computerized Sewing Machines, retrieved 13:07, 15 April 2011 (CEST). With that kind of machines, a user can focus on design and the needs to learn how to interpret orders from machine like replacing the threads.

According to Wikipedia and other sources, the first modern day computer controlled sewing machine was built by Orisol in 1987 for making shoes.

Design software exists in various form. Designs are both sold and also available as open "source". Converter software between various control formats exists.

Computerized embroidery

More or less according to Wikipedia, the basic steps for creating an embroidery are as follows:

  • Get or create a digitized embroidery design file
  • Edit the design and/or combine with other designs (optional)
  • Translate to machine executable code (optional)
  • load the final design file into the embroidery machine
  • stabilize the fabric and place it in the machine
  • start and monitor the embroidery machine

Software and repositories for embroidery

Disclaimer: None tested so far, therefore none we could recommend.

Franz Xaver Simm: Die Stickerin Oil on canvas, 94 x 68 cm

We can distinguish between several types of software, although sometimes the frontiers are blurreded.

  • Software to create designs for "manual" embroidery
  • Vectorizers (can translate a bitmap to vector formats)
  • Digitizers (can translate a vector format to CNC code)
  • Converters can convert from one format to another (may include the above)
  • Editors (can draw digitize, but sometimes also vectorize)
  • Viewers (allow to view files, useful for script generated formats for example)
  • Organizers (help to organize designs)
  • Complete embroidery CAD Suites, can create sophisticated drawings and supports all the design stages. Therefore, high-end software includes all of the above.

Design and multi-purpose tools

Free just design tools

(these will just create patterns for hand stitching)

  • KXStitch aims to produce software to allow the creation and editing of cross stitch patterns. Runs under Linux/KDE. See kxstitch wiki
Free design tools for computerized embroidery

These can output CNC file formats. You may have to use a converter to get it working on your machine.

  • Embroidermodder. Free software tool (under development as of April 2011) that allows the user to add custom modifications to their embroidery designs. Can read/write 5-6 formats. Started in 2004 by Mark Pontius, last update on 11/2010 when last checked (April 2011). I installed this on Win 7 64 and the program runs. I created a simple text and was able to save a .dst file and then open it with Wilcom TrueSizer. Some stiches seem to be wrong.
Commercial embroidery/stitching design tools
  • BuzzTools sells a series of design tools, e.g. design management software. graphics to stitches, words to stitches, etc. (between $99 and 300)
  • Bernina, the sewing machine company sells several products for their own machines. US link, Switzerland (de/fr). Prices fairly expensive, i.e. must have design program is about $2000. There is one free program ArtLink 6 (CH) / Artlink 6 (USA)
  • Embrilliance. A (relatively) cheap multi-purpose tool for converting/mergin/lettering etc. Supports most embroidery formats, but can't import "normal" 2D graphics. (Mac/PC)
  • Embroidery software by Pulse. Various products like Tajima DG/ML, Tajima Librarian, Tajima Passport, Embroidery/Illustrator. High end/expensive.
  • Stitches in Motion has Sew Art (software for converting clipart or other forms of raster and vector images into an embroidery file). It can output in PES or JEF. For other formats, you will have to use a conversion program.
  • Embird Embroidery Software sells several programs, A base program (Basic Embird) plus several plugins e.g. Embird Studio (digitizing). Can read/write many formats.

Free converter tools and other utilities

Free utility tools (converters, digitizers, etc.)

Some of these are available as plugins for graphics programs

  • Planned since 2009: The Brother Liberation Front announced working on and Inkscape and Gimp plugin named Yarnscape and Crafty Gimp respectively. If this will happen, then Inkscape could become a free embroidery design tool.
apt-get install python-shapely
cp embroider.inx embroider.py PyEmb.py ~/.config/inkscape/extensions
In Inkscape, the extension is available in Extensions->Render->Embroider
Only works, if you create a drawing with filled regions that are converted to pathes and are not grouped. (So no grouping, no strokes, etc. !)
Result *.exp will sit in your home directory or some other place ...

I managed to create a stitched oval and display it with some *.exp viewer. - April 2011.

  • Joachims's freeware include Pesview 1.3.0, a Viewer/Conversion-Tool for PES/PEC/PCS/DST/SEW and EasyPEC for converting PES.x to PEC 1.0
Free converters/resizers/etc from commercial companies

  • WILCOM TrueSizer. Read, resize, rotate and convert many popular industrial and home expanded/condensed file formats. Can't write .ART. Windows, free but registration is required. Tested under Windows 7 64 bit. Software works, but so far I don't have a sewing machine to test for real (April 2011). Anyhow, as far as I can tell, this seems to be the one of the two best free converters.
  • multi-converter from Stitch & Sew. Can read designs from manufacturer's cards to the hard disk and the other way round. Registration required. I Installed it on Win 7/64, but did not understand how I could convert files within my hard disk.
  • Bernina Artlink, a free multi-purpose utility program form Bernina. Can resize, rotate 45 degrees, select stitch color, read/write many embroidery formats, display hoops for various types (also other brands), write to various hardware. As far as I can tell, this seems to be the one of the two best free converters. I somehow got the German version, but there is also an English edition ...
Commercial converters
  • SewWhat! from Stitches in Motion. Can read most formats and write a lot of formats (but not .art). Between $50 and $65. Free trial versions.

File formats

There are several kinds of formats, in particular

  • All sorts of 2D bitmap and vector formats for the drawings
  • Embroidery and sewing specific file formats that work on a range of machines and also can be used as exchange formats.
  • Machine formats that are mostly brand or even type specific
List of formats

(Not sure that it is correct. It seems that there are about 20 different formats and it is not very clear what formats a specific machine from various Brands can read. E.g. I believe that most Berninas can read, .pes, .art and .exp)

  • ART Bernina
  • PEC Bernina ?
  • CSD Singer
  • DST Tajima
  • EXP Melco (Bernina?)
  • FDR Barudan
  • HUS Husquarna
  • JEF Janome
  • PES Brother (Bernina?, Bablock, Deco)
  • SEW Elna
  • PCS,PCQ,PCD,PCM,VIP Pfaff
  • SHV Viking
