The four cable drawing machine built by David Bynoe, currently performing at the Telus Spark Science Centre in Calgary, Alberta, is hypnotic to watch as it makes and remakes beautiful patterns in the sand of spectacular precision.
Each of the four stepper motors is connected to a pulley and string. By winding in or letting out string on each corner the computer can position the draw head anywhere in three dimensional space, or at least within its work envelope of roughly 590x590x220mm.
The machine is controlled with LinuxCNC using a custom kinematics module and python script written by Kevin Loney. Its input files are standard g-code, the same format used for controlling a CNC mill, all the weird coordinate transformation math is handled by the kinematics wrapper.
