Export DXF - Edge_Top and Edge_Bottom - DLP 3D printer for PCB etching

#1 Post by MarkEd » 29 Jul 2020, 00:25

Hello

Please add ability to set "Edge Width:" to negative value(for example -0,05mm or -0,1) in "export DXF" - Edge_Top and Edge_Bottom layer.
This would be useful for PCB etching with DLP 3D printer.

Using DLP 3D printer for PCB etch - surprising results:

Track and pads are to wide. Edge Width = -0,05 in dxf export would probably be perfect.

We will consider allowing negative value in Edge Width but it seems counterintuitive in most cases therefore the software changes negative value to minimum positive one.

It would be great if it would show up in the next version.
It is probably counterintuitive when milling, but it would do the job with UV exposure.
