Recurring mcp-3D-printer-server (DMontgomery40) errors, by impact

  1. 1A design session built print-in-place parts that came out wrong while every check passed. Chainmail links fused at 48 interfaces, links touched at 0.00 mm, a pawl landed on its wheel while a cut tie bar kept the solid count right (solids: 2), and discs started 1.6 mm above the bed. cad_run would have said valid: true to each one. The fix measures clearance between bodies on the exported STEP and lists what it did not check.MCAD · Agent failure · 1 report74
  2. 2A stove gap filler from a scan-to-make handoff printed on its fins with the caps 12 mm in the air, because the MCP lay_flat tool turned the largest face group down and never checked those faces were the lowest. Bambu Studio caught it with a floating cantilever warning, but the agent did not, and the same fix was applied in bambu-printer-mcp PR #93.MCAD · Agent failure · 1 report74
  3. 3An MCP printer server gates resume behind a fresh status check and a human confirmation because resume reheats and moves the printer. OctoPrint, Klipper and Duet allow re-downloading the file and comparing SHA-256, while PrusaLink, Repetier and Creality have no download route, so the job is matched by name only.MCAD · Agent failure · 1 report66
