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.

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.

Build log

  • 11 June 2014: soldered pins on the Pololu drivers and soldered the CNC shield
  • 12 June 2014: connected the shield to an Arduino Nano (while waiting for an Uno). Connected a motor and tested the shield.
Uno to Nano
  • 13 June 2014: added connectors to both motors and ran a simple test
  • 15 June 2014: embroidered a lemming by hand
