** Found 1 unconnected pads **
ErrType(2): Unconnected items
@ (137.947 mm,91.498 mm): Track 0.250 mm, net [GND] (2) on layer F.Cu, length: 0.067 mm
@ (139.200 mm,93.100 mm): Pad 3 on B.Cu, Non-copper of JP1
PS: Not related to my question but… well: In order to get the error message I created an entry in the “Create report file” box and got this:
This looks like a custom pad. The footprint editor sets its zone connection to None by default. (this is because there is no thermal spokes option for custom pads.)
Either select pad to zone connection as solid for this pad or connect it manually with a trace.
(Or use a normal pad as i kind of fail to see the reason for using a custom pad for this footprint.)
You could for example use SolderJumper-3_P1.3mm_Bridged12_Pad1.0x1.5mm which does not use custom pads.
To fix the pad settings copy the footprint into your personal lib and edit it in the footprint editor. But be aware that it will be near to impossible to solder the pad if it is fully connected to a copper zone.
