Removing the boards works best by using a twist motion around the z-axis. A brush should be nearby to clean the grooves. | Removing the boards works best by using a twist motion around the z-axis. A brush should be nearby to clean the grooves. | ||

Pins of through-hole mounted devices also do not form automatic top-bottom connections. This especially frustrating with the eagle autorouter, because I found no way of turning this off. Sometimes you can compensate by soldering also on the top side of the part, but very often there is really no space for that. Best thing is to manually overwork the board in eagle. | Pins of through-hole mounted devices also do not form automatic top-bottom connections.

=== Routing === | |||
While the eagle autorouter tries to bundle wires closely together, for voronoi shaped pcbs, this is not so optimal. | |||
You can still use the autorouter, however I would recommend it only on the bottom layer. I use a 12.5 mil routing grid usually, and * for bottom N/A for top. | |||
Then I move the wires around, so that the sidewards distance is maximized. | |||
