Nice job, Lawrence. When I get GWiz into good enough shape to release, I'd like to be able to "steal" your code and make a wizard out of it. Would you consider GPLing it? Or better yet, releasing it to the public domain. I say "better yet" because then you can just add a single line comment: (Released to the public domain by Lawrence Glaister.) That seems easier than the multiple lines for the copyright notice plus the GPL license reference.
Some changes I might make: 1 -- Use "named" o-words, instead of the numerical ones. -- That's a relatively new feature. 2 -- I think I would have put the index slot on the inside of the main slots, instead of the outside. That way you need only one long reach opto. When converting it to a wizard, I would make that an option. 3 -- I would make the actual wizard a radial slot wizard. Then to do the encoder, you would invoke the following: A -- A radial slot wiz to do the index slot. B -- A radial slot wiz to do the main slots C -- A bolt hole circle wiz to do the mounting holes D -- An outside circle wiz to do the outside perimeter E -- An inside circle wiz to do the inside hole. Of course, one could make a super wiz to do the whole thing. Ken Lawrence Glaister wrote: > Hi Kirk, > Looks like you have been having fun in gcode.
