Thank you guys.
Joan_Sparky, yes there is quite som information about exactly that. Which makes me go back and double check every footprint on everything but passives, I guess. But that's fine. The only thing that concerns me is if I edit a footprints origin and update my layout, will the components rotate and/or place differently, or will only the position on the board and the rotation values change?
PCBway has an example centroid file for reference: http://www.pcbway.com/img/images/pcbway/a-sample-of-PCBWay-Centroid-File.txt
All though PCBway does not specify it has to be exactly like this, comparing this to the .pos file output from PCBnew I can see some differences:
- Several more X/Y positions, Mid X, Mid Y, Ref X, Ref Y, Pad X and Pad Y. I'm guessing Mid X and Mid Y are what's in the -pos file. The other two positions (Ref and Pad) I'm not sure what is. From what I can see, Mid and Ref always equals the same.
- It does not state the value. I can edit this out.
- Units are mil, KiCad units is inches when output in imperial (I was told that CMs wants metric?)
I also have a new concern. I try to move the Origin Point to bottom left corner of the pcb. By doing this I'm placing a red origin point which moves each time a place a "new one". All good. But there's also a grey similar looking origin point on my pcb which I don't know where comes from. What is this? Can I move it? Delete it? Do I need it?
