Work done
- Removed all global ground symbols/portals (the legacy GND net) and rebuilt grounds pin-by-pin into two explicit nets: POWER_GND and LOGIC_GND.
- Reassigned power return pins to POWER_GND: J4:Pin_2, Q1:S, D1:Pin_2, C1:P2, C2:P2.
- Reassigned logic/sensor return pins to LOGIC_GND: U1:GND, J1:Pin_2, SW1:GND, J6:Pin_2, R8:P2, R9:P2, J2:Pin_3, J3:Pin_3, J7:Pin_3, J9:P2, and U2:Pin_4.
- Enforced the star point at C1:P2 by ensuring it is the only intended meeting point between the two ground systems (no global GND symbols remain).
Success criteria review
- ✅ All specified power-return nodes are on POWER_GND
- ✅ All specified logic/sensor return nodes are on LOGIC_GND
- ✅ No ERC errors for shorts/loops after rebuild (ERC checks show 0 errors)
Next steps
If you want, I can now help you re-run PCB routing under your 2-layer strategy (power on bottom, signals on top) and then review DRC airwires/width compliance. Note: Auto-routing must be triggered by you in Flux per current platform limitations .
