A scan measurement app and its MCP server kept six significant digits in answers, so large absolute coordinates lose 0.1 mm or more. session.reset reported success after a failed reset, and picture tools claimed to be read-only and still overwrote files.
Recurring agent failure issue in ScanRuler (CNCKitchen)
What engineers report
A recurring agent failure problem in ScanRuler (CNCKitchen) that mostly hits the mechanical designer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 8-9 2026 (Nov 8 8:41 AM ET through Nov 9 6:41 AM ET digests plus the Haitch editions). Verified live 2026-11-09: 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 user prints parts, scans them and compares against the STEP. "The colour map shows exactly where the print warped or shrank... But that's where it ends." Today the fix is "editing the CAD by hand and guessing from the colour map," and the tools that do proper distortion compensation "are expensive commercial packages." The ask is a compensated mesh export, with a pinned bed face and a strength setting. Measured data that never flows back into the model. A first-person workaround with a clear price gap.MCAD · impact 74
- The scan-to-CAD guide says inner wall and inset take only a number, but the source accepts a parameter expression. An agent following it types the wall as a number and loses the parameter link. Docs and code drifted, and the agent trusts the docs.MCAD · impact 66
