D02 light-off command between tiled Gerb

December 13, 202

GBTiler needs to take an extra step as it tiles the second and all following instances of circuit board files, assuring that the first coordinate placement and light action directive effectively turns off the light (which causes lines to be drawn) between tiled coordinate data sets from each source file.

Currently, there are times when two or more boards end up being graphically connected by an unintended line, linking the last point of the previous tiled circuit board with the first point of the current tiled circuit board. Programs that output Gerber format files typically have never had to worry about turning off the light at the last line or aperture exposure. In a single file, there is no more drawing following that last point or stroke.

When tiling Gerber files it becomes necessary to turn off the light between files.

Project admin Ted Havelka is posting this bug, for information to users of GBTiler and as a reminder that he needs to amend the bug.
