?I have discovered a very easy way to get a stencil file for the board outline - merely copy the entire project and edit the milling outline to lie on the "dimension" points. Run pcb-gcode? and use the resultant gcode text file for the stencil outline.? If the tool used is the same as for "etching", the resulting stencil will be half a tool diameter? too small - really of no consequence, and it may help in getting the stencil aligned.
Attached is a pic of my latest stencil which mounts a mini USB connector (pins 0.5mm spaces 0.2mm) and uses 0.19mm mylar.? At first sight it appears to leave a lot of solder paste on the pcb so the next trial will use 0.125mm mylar.? Picture distortion is due to macro lens on camera
