A toolchanger printer validates its Klipper macros against CAD clash checks, and the owner still cannot watch the moves play out. The macro sequence already exports a JSONL timeline, one move per line, but getting it into FreeCAD takes hand-kept offsets (X = model X + 420.0, Y = model Y - 30.5), a Z zero taken from a sweep log, and solids grouped into bed (115), gantry (58) and carriage. The timeline's tool field is the extruder active before a pickup, so which head is on the carriage has to be worked out from the dock path.

What engineers report
A recurring agent failure problem in vt350 (dvystrcil) that mostly hits the mechanical designer.
Failure pattern: validation / failure
Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: 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

- Answering what sits where meant loading a 50 to 170 MB FreeCAD file, so the vt350 project now writes a per-part bounding-box index beside every model. A 917-part model took 60 s to compute. Along the way they found the group path was wrong for any object inside a group inside an App::Part, and the mesh export still has that bug.MCAD · impact 66
- To answer a layout question like what sits on the underside of the filter, Claude starts freecadcmd and loads a 50 to 170 MB model, a few minutes per question. The models live outside git, and bounding boxes differ between GUI and headless runs (0.14 mm on one pass).MCAD · impact 66
