I am looking for free software to design and mill simple front panels. I need 2 layers at least to hold a bunch of 60x60 5V solar panels (plus one panel in the back, probably). At worst I can drill separate panels that I would glue together to pinch/sandwich the panels.
Front Panel Designer looks good, but I would better stick to FLOSS, like, may be Inkscape + pyCAM (but how would I handle Z profiles? with layers?).
Not sure were to invest my time and the limits/burdens that go with them. Do you have good suggestions?

+Peter van der Walt thanks a LOT. BTW I like programmable (hence fully parametric) CAD so much that I was even considering using openscad to try and do the job!
What are the panels for? Here is another web based SVG to G-Code generator: http://www.makercam.com/
Thanks also, even though I am still evaluating jscut (really nice so far). Its UI seems smoother but I would not stop to this.
I just want to drill a 2-step basic frame/holder for 8 small 5V solar panels, placed in a row to minimize the overall height.
They power an attiny85 + temp sensors + 12V fan to move the hot air from my veranda to the inside of my house (or extract it during summer). I’ve already milled the PCB, so it was the right time to move further to 2.5D 
I recommend HeeksCNC.

It is part of HeeksCAD but one doesn’t have to make the designs in HeeksCAD. You can import DXFs or SVGs. HeeksCNC allows you to generate profiles, drilling operations, etc. You can have tabs added for cut out operations. It can also add little loops to smooth out the start on cutting profiles. You can set the maximum depth for a cut and it will make multiple passes for greater depths. Perhaps makercam does all of these things, I have used it yet. I plan on checking it out on my next project for our Shopbot.
