drawing machine, arduino based
Description
this is a drawing machine based on an arduino uno. it is similar to other designs available on thingiverse. i chose to design my own because most available machines do not hide away the electronics and the motors. all in all i was surprised how easily such a plotter can be built. operating the plotter is also easy when using migrbl that can drive the servo on the z axis. i generate most gcode either with inkscape, carbide create or with my own python scripts (e.g. to generate cycloid drawings). components used: - 1x arduino uno - 1x arduino cnc shield version 3 - 2x stepper drivers a4988 (soon to be replaced with silent tmc2209 - 2x nema 17 stepper motors - 4x 8x500 mm carbon rods - 8x 8x12x15 mm brass bushings - 2x 20 teeth, 5 mm hole pulleys - 5x 20 teeth, 5 mm hole pulleys with ball bearings - 1x timing belt gt2, 6 mm wide, around 2.5 m long - various 3 mm hex bolts i bought almost all component online in china. more information can be found here: https://www.muellerr.ch/arduino-drawing-machine/ video of the drawing machine in action: https://www.youtube.com/watch?v=ujbIIkblkWw
