The img2track program reads a graphic image file and converts it to pattern data formatted for a Brother KH‑900‑series knitting machine. The pattern can be loaded into the knitting machine with a USB-to-serial adapter cable. Img2track works with Brother models KH‑930, 940, and 950i. (Img2track is pronounced "image to track".)

The img2track program is original code. It was inspired by the earlier Adafruit hack. (See credits in the program's About box.)

Photos of knitting produced with img2track can be seen at this project page at Ravelry, and elsewhere on the web.

May 2014:
After hundreds of hours of additional development, we are pleased to announce img2track 2.2, the first release for both MS‑Windows and Mac OSX. It has many improvements, including an enhanced pattern viewer, multicolor knitting, and several bug fixes.

To fund the development of img2track, we are releasing it as commercial software. You may use the program free of charge, but patterns loaded into the knitting machine are limited to a maximum width of 100 stitches. To use the full 200 stitches width, you must purchase a registration key. We hope you will enjoy img2track, and can support its continued development.

USB-to-serial cable

To get the pattern data into your knitting machine, you will need a USB-to-serial converter cable, with a custom connector. See our tutorial for making this cable. Or you may order one from us. Brotherlink BL1USB or BL5USB cables may also be used.

Installing driver software

The cable requires driver software, which must be installed on the computer.

Windows Vista, 7, or 8:
With the computer connected to the internet, plug in the USB end of the cable — Windows should install the necessary driver automatically. If not, follow next paragraph.

Mac OSX (or Windows if auto-install fails):
Download the appropriate driver for your computer (32 or 64-bit doesn't matter, the download is the same). Follow the instructions for installing the CDM or VCP driver in the FTDI Installation Guide for your computer.
