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.

Build log

• 11 June 2014: soldered pins on the Pololu drivers and soldered the CNC shield
  • 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 arduino GRBL library on the Arduino
  • Created a simple drawing in Inkscape, converted the path to Gcode with this extension, and have sent the gcode to the arduino with the Universal Gcode Sender
