TinyG XY Plotter

thingiverse

This XY plotter owner developed the machine to test their ARC code for TinyG, a multi-axis stepper motor controller that supports up to 254 networked motors. The creator is open to others experimenting with the plotter and even welcomes local tinkerers to get in touch. The metal parts are from Contraptor Framework, with aluminum used for all pieces except the Y-axis angle rails, which are made of home depot steel angle. The design features laser-cut accuracy and is scalable up to 8ft tables with minimal adjustments. It uses 805 skate bearings (5mm centers), 10-24 and 1/4" hardware, and 1/4" threaded rods for sandwiching parts together. The wood is 1/2 inch plywood, cuttable in one pass on a 40W Epilog laser with a 4" lens. Instructions are available upon request, while NEMA 23 stepper motors are recommended. Contact the creator at riley@gmail.com for more information about TinyG and potential collaborations. The electronics can process gcode over USB serial port or store programs in program memory, as demonstrated in this video: http://www.flickr.com/photos/rileyporter/4651309872/in/photostream/.
