Good workflow processes

How do you go from a CAD design to a finished piece of solid object? Include in this document or series of documents as many of the steps and background info on the tools and software as needed.

Once this process gets started, students and others can add to the body of knowledge to make it truly usable.

A good understanding of partwizard will be useful.

Project Wizard will be useful to some extent for getting started, but there aren't a huge amount of files in the collection.

Being able to go from hand drawn artwork to executable shopbot file will be important.

ShopBotDustCollection

A way to get the dust off of the table without it going all over the room. The SETC Fab Lab has a pretty good design, there are some others as well. The dust collection system needs to be hooked into the room's vacuum system. The dust collection system should probably be properly grounded

Limit switches

A way to have the machine know when it has reached the safe end of its axis. These switches need to be tied into the estop circuit.

Z Zero tool

This will be a way to accurately measure the height of the tool relative to the top of the table or the material. It will probably be tied to the estop circuit. When you bring the z axis down, and the z zero tool is on the workpiece or table and connected to ground on the tool, the bit will touch the tool, ground, trigger the estop, then stop the tool. This will allow a known z height, maybe an eighth of an inch, which can be factored and the tool can then cut.
