Hi All:
A new version is online, no changes other than a new shortcut on the screen named Gearotic-Spur, its a small program for creating Spurs for 3d Printing. It allows for decorating STL's with bearings, collars and spokes. It is an early beta , I haven't as yet done a tutorial, but that will come.
Notes:
1) It doesn't , as of yet , remember anything, each run of the program is a fresh run.
2) It is 3 stages.
First stage: Create gear tooth array, if you require backlash, set the backlash to .47 or so. Helical is also available as well as cycloidal.
Second Stage, decorate the front and/or back of the gears with bearing races, flanges, collars or clamp collars.
Last Stage:
Only spokes are now shown, select spokes and manipulate them as you wish. Press "Integrate" to create the end high definition
STL's of the gears. That's it, gear is complete, export buttons appear on screen.
These gears are created as Signed-Distance-Functions. This is why on the spokes screen I separate you from the gear outline,
SDF's of gears are very slow as they are a tough computation in the real time rendering of sdf's. The integration allows for a final computation of the stl with a marching cubes algorithm set to triangulate all details to a minimum of a function of the pitch radius, this is to allow very small gears for resin 3d printing with radii less than 5mm.
Let me know if you run into troubles. I hope this aids in producing gears that lock to shafts more easily for you.
Regards
Art
