I had posted my original experiments with the guilloche generator in another thread but the software has morphed into something more complex over time. So, if somebody wants to play with the current Beta version, it is HERE. Operates so far only in Demo mode until I have the license distribution method set up.
To give an idea about what it can do right now, see sample screen pics below. For any possible pattern, it can high resolution bitmap output for use in Vcarve (e.g. flat-bottom vcarve or inlays) or generate g-code directly to execute with a v-bit (direct vcarve only without flat bottom). I thought about dxf output but that would lose all depth information and does not look promising. For now it can do circular, spiral, linear and radial guilloche work. At some point I would like to do rotational indexer output but need to find a way to specify non-cylindrical shapes. Most columns or pens have conical or barrel type shapes, after all.
