Thank you for response.
Not sure exactly which file to attach the .PRO or .kicad_pcb.
I tried but, apparently, new users are not allowed to attach any files other than screenshots.
Is there a simple workaround? (no, not interested in Cloud/etc).
Thanks
[EDIT] I Redid the tracks at top in Zoomed-in view and was able to properly attach. That problem is solved.
At bottom, I’m thinking it’s related to the Button Switch (as stock part). Two pins on right are internally connected so, only one track is needed. But, the unconnected pin (doesn’t matter which) generates the ratnest-line. Still, it works fine for my CNC need but, would like to understand it.
