Hi guys, thanks for the responses, and apologies for the delay in getting back to you, I had issues logging in
If you take a look at the pictures below you will see how I have to use an engineering approach to the PCB’s, as many are multi layered due to the positioning and sizes of the connected devices. For small PCB’s it’s not a problem, but you can see the last picture is the type of thing that causes issues. (Edit, only one picture allowed per post, will have to span across a number of them)
It is so large that it is impossible to keep flat with the tools I have and also is larger in area than the engraver I have. As a result it is a multi part machining process, and during machining it will continue to flex as it is impossible to hold without the clamps getting in the way of the work. This causes tool wander and a lot of loss of accuracy.
However the design in DXF form allows me to accurately place the switches, SMD LED’s, header pin holes plus all the necessary cutouts that are required to clear the rest of the assembly.
Like I said before, the ability to put a DXF file onto the design and copy the entities or transfer parts to Fritzing is what I need
Cheers
