CUT40 Board Opening Map

This is the fast internal opening map for CUT40 once torch, air, clamp, and guide-hardware branches are already bounded.

Open Only After Proving

fresh CB50 front-end stack is already proven
dry external air path is already proven
clamp and guide-hardware branches are already separated
freehand cutting is already compared against guided cutting

First Internal Targets

Board or internal group	Open first when...	Key connector or checkpoint	Best local file to open first
Air-control valve branch	air routing is wrong or unstable	external-air routing and valve behavior	workbook sheet `coolcut40air`
Torch and start-control branch	start is absent with healthy air and fresh front end	start-control branch after air is proven	`Cut40_owner_manual.pdf` and workbook
Main output branch	start and air look healthy but output still collapses	output branch only after externals are proven	`Cut40_owner_manual.pdf`

Connector and Board-Family Reminders

Keep guide-hardware complaints outside the chassis until freehand baseline is proven.
Do not blame the machine while hose contamination or air routing is still unproven.
CUT40 and CoolCut40air share enough air-branch behavior that the workbook branch remains useful here.
Do not open the machine while only guided cutting is bad and freehand cutting still looks healthy.

External Parts Exit Paths

If the opening pass shows the complaint still follows the torch, guide, or air branch, leave the board path and use the official ordering flow instead.
CUT40 parts category: official parts path
CB50 torch 07001710: use the official parts path above.

Stop Rules

Stop if guide-hardware correction removes the complaint.
Stop if a clean air path changes the complaint immediately.
Stop if freehand cutting is healthy and only guide hardware fails.
Stop and return to the full guide if air, start, and output evidence still overlap after the first opening pass.
