Your goal: make the 555 + CD4017 LED chaser work reliably.
Plan:
- Rewire IC3 astable: tie THR+TR to a TIMING net; move C4 between TIMING and GND; connect R1 from VDD to DIS; wire VR2 as RB (CW->DIS, WIPER+CCW->TIMING).
- On IC2, remove CARRY_OUT-to-GND; keep CLK INH low; RESET low.
- Add two 100nF Capacitor decouplers: IC3 VCC-GND and IC2 VDD-GND.
- Re-run ERC/DRC and verify CLK from IC3 to IC2. Let me know if you want any changes.

Short answer: not yet. I see a few blocking issues in your Flux schematic.
-
555 timing node is wrong
-
CD4017 carry-out shorted
-
Decoupling caps missing
- Add a 100 nF between IC3 and another 100 nF between IC2, placed close to the pins. Example part: 100nF Capacitor.
-
LED resistor values inconsistent
Notes from checks
- ERC reports “Missing Power” on IC2 and IC3. Your nets show power on Net 41; just make sure your supply symbol V2 orientation and net naming are correct (e.g., rename Net 41 to “VCC/5V”) so ERC recognizes it.
If you want, I can apply these fixes to the schematic and add the two 100 nF caps for you.
