Temperature and Humidity Sensor Node Design

flux

Still blocked. The backend is still reporting the same active out-of-credit job:
auto-layout-892da960-99ac-4017-ae4f-b8dc1eedc351
I was able to:
  • Re-run the board check: the board is valid.
  • Loosen the added 28 V keepout zones so they are less likely to block gate/filter routing.
  • Confirm routing warnings remain for a few blocked logic pins, but those are secondary.
The actual autoroute start is still rejected because that old job is still active server-side. It likely needs Flux support/admin cleanup if the UI dismiss did not remove it. Use this exact request:

Please clear stuck auto-layout job auto-layout-892da960-99ac-4017-ae4f-b8dc1eedc351 from:
https://www.flux.ai/sddvox/open-hornet-16-channel-28v-magnetic-hold-driver

It remains active with status outOfCredit and blocks new autoroute jobs even after UI retry.

I’ll retry the backend autoroute now and, if it starts, I’ll review the post-route DRC/airwires and continue cleanup.

flux

Still blocked. Autoroute is still rejected by the backend because the same job is active:
auto-layout-892da960-99ac-4017-ae4f-b8dc1eedc351
status: outOfCredit
The pre-route check also timed out this time, likely due to server load, but the decisive issue is still the stuck out-of-credit job. It needs Flux-side cleanup before I can rerun routing.
