G-code unit scaling #14

Closed helicalbytes closed 8 years ago

helicalbytes commented 8 years ago

I have some text from SVG fonts ready to convert to g-code for testing. Just want to check the scaling. That is, how many g-code units equal one physical unit (e.g. cm) on the drawing surface?

goatchurchprime commented 8 years ago

The scale is set in mm. One G-code unit for 1mm.

On the current whiteboard setup we can safely go X-200, to X200 and Y-200 to Y200

Z is ignored, but takes time, so go up and down in it by 1mm. May be used for the pen servo later.

See Issue#15 about corner rounding and possibility of non-outline letters. (More like hand-writing type letters).

For emphasis we'd do more interesting shaded letters where areas are hatched or painted in.

Thanks for info. Regarding single line (as distinct from outline) fonts, I did have a look for some of these a few days ago. I found a few that are used for engraving and other similar applications, but I wasn't sure if there are any that are widely known and used?
