Embroidery machines are pretty expensive. The software too. In this project I want to convert a normal sewing machine into a CNC embroidery machine.
For this a XY table is needed to move the embroidery hoop under the needle. The sewing machine needs a small modification to control the speed and to monitor the needle position.
I would like to start from SVG images, and convert this to GCODE to send patterns to the machine.

* something to measure the needle position
Two ways of sewing machine operation:
** continuous (quilting) This is probably the easiest way, because you only need to control the speed. Basically "on" with certain speed and "off"
** end-point punching (more like embroidery) Needs either accurate needle position info or a motor to make exactly one punch. In the second case this would be the Z axis.

* 11 June 2014: soldered pins on the Pololu drivers and soldered the CNC shield
** [http://blog.protoneer.co.nz/arduino-cnc-shield-v3-00-assembly-guide/ assembly and instructions]
* 12 June 2014: connected the shield to an Arduino Nano (while waiting for an Uno). Connected a motor and tested the shield.
** Have put the [https://github.com/Protoneer/GRBL-Arduino-Library arduino GRBL library] on the Arduino
** Created a simple drawing in [http://www.inkscape.org/en/ Inkscape], converted the path to Gcode with this [http://wiki.linuxcnc.org/cgi-bin/wiki.pl?InkscapeHowto extension], and have sent the gcode to the arduino with the [https://github.com/winder/Universal-G-Code-Sender Universal Gcode Sender]

* 13 June 2014: added connectors to both motors and ran a simple test
* 15 June 2014: embroidered a lemming by hand
