I’m trying to realize a double side PCB, complete with some labels.
I’m getting some problem in different steps of the process.
- Initially, I wrote the labels I need (i.e. +5V, or LED+, or similar, to address me when soldering the components) directly on the PCB layer (front / back). Nevertheless, this way, the machining process will take a lot of time more than only routes.
- I’d like to have more control when machining the PCB outline / structural holes and so
Thus, I decided to use FlatCAM only to realize the isolation routes / holes / double side mills processing, and use a CNC dedicated software (thinking about Aspire) to realize the labels and the outlines/structural holes.
To get this, I exported from PCBNew the layers Front, Back and custom (where I imported the outline DXF to help me in positioning the components), choosing SVG as format.
The thing seems working, but when I import the SVGs in the CNC software, the draws are very little (i.e this PCB is 4060 mm, the SVGs are 46 mm), altought in kicad export dialog windows the scale is 1:1
This get me very frustrated, as it becomes really hard to create and place the label / holes and to set the milling parameters.
What have I to do to export the SVGs from PCBNew keeping the right dimensions?
