TinyG XY Plotter

This is my XY plotter that I created to test out our ARC code for our multi axis (up to 254 networked) stepper motor controller called TinyG. You can read more about TinyG here.

I do realize that it would not take much more to create a z axis and make this a CNC machine. This is the plan. However if anyone else wants to mess with it. Please go for it. Also, if anyone is in the Washington DC metro area and wants to mess with the machine let me know.

The metal parts are all made from the contraptor frame work. (www.contraptor.org) However, that being said you do not have to drill the holes in every part. Just drill them where you are going to need them.

All metal is aluminum with the exception of the Y axis "angle rails" these are made from home depot steel angle. Both steel and alum angle is 1" x 1" x 1/8". Possibly the coolest thing about this design is the fact that all the stuff that needs to be accura
