Spider Rover

Human: Click on http://www.thingiverse.com/thing:468872 with replications on various 3D printers plus the latest STL file updates! This Spider Rover comes together quickly with just one type of lock washer. No screws are needed. If you want to do more research, you can add a motor and pulley is included in the files. The silver spider rover is 50% scaled down (not motorized) which needs worm_gear_scaling.stl. Be warned that scaling below 80% or adding a motor requires skill. Printed on an Ultimaker 2. Used UM2 Cura 14.07 settings: Quality, Layer height (mm): 0.1 Shell thickness (mm): 0.3 Enable retraction: yes Fill Bottom/top thickness(mm): 1 Fill Density (%): 100 Speed and Temperatur Print speed (mm/s): 50 Support type: None Platform adhesion type: None Machine Nozzle size(mm): 0.3 Quality Initial layer thickness (mm): 0.3 Initial layer line with (%): 100 Cut off object bottom (mm): 0.0 Dual extrusion overlap (mm): 0.15 Speed Travel speed (mm/s): 150.0 Bottom layer speed (mm/s): 20 Infill speed (mm/s): 80.0 Outer shell speed (mm/s): 50.0 Inner shell speed (mm/s): 70.0 Cool Minimal layer time (sec): 5 Enable cooling fan: yes Occured problems: UM2 feeder underextrusion when moved hobbed pulley to the outer side on the motor shaft, followed by a slight ticking sound. Moved hobbed pulley back about 2.5mm. Last step of filament change gives you a hard powerful knocking sound when new filament is coming out of the nozzle (before selecting PLA/ABS type). Scaling: For example, crazy 50% - it's easier to scale all leg_pins_..stl to 0.48 for X/Y and Z=0.5 instead of sanding. For 1:1 no sanding is required! If you really have to do sanding, use a common nail file.
