After Reorient, 'make it N mm tall' and the bed pre-check still used the authored pose, so a rod laid flat and asked to be 50 mm tall printed 2.5 mm tall. A 3MF part placed with a mirroring transform was flattened inside out, a 10 x 20 x 30 box measured -6000 mm3 in the STL handed to the slicer, and a 40 x 40 mm sawtooth underside was classed as a harmless chamfer so a part needing supports was reported as fine.

Analyst note
From the Grok pain-radar digests, Nov 9-10 2026 (Nov 9 7:41 AM ET through Nov 10 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-10: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

- A 300 s client cap killed a bed mesh run while Klipper kept probing; the runner recorded a cooldown failure, never reached SAVE_CONFIG, and the mesh had to be saved by hand.MCAD · impact 66
- A spool sync writes a temperature record with no material family, and the safety verifier compares None to PLA before it looks at the real G-code temperatures. Every slice gets refused, including correct G-code.MCAD · impact 66
- In the same tool, a long calibration reported The send did not succeed while the printer kept running, and worse, a result prompt that timed out counted as Discard, which for PID is FIRMWARE_RESTART; now a timeout sends nothing and Accept or Discard re-checks the printer is idle first.Firmware · impact 66
