Walt — Simple Man Takeaway
Vacuum does not hold the part because it likes you. It holds because the seal, surface, timing, and motion all agreed for a moment.
Plain-English Summary
Use this flow when a vacuum system fails to pick, drops parts, releases late, releases early, marks product, or becomes inconsistent during a transfer. Vacuum failures are often a combination of cup condition, product surface, air supply, vacuum level, timing, motion, and release path.

Support-System First-Check Flow
Field Checks
- Identify the failure point
- Inspect the cups
- Check the product surface
- Measure vacuum at the work
- Check generator supply
- Check timing
- Check motion profile
- Check support and guidance
Watch Out For
- Vacuum switch proves a spike but not a stable hold
- Cup material wrong for product surface
- Motion exceeds holding capability
- Exhaust or muffler restriction
- Tubes too long, leaking, or collapsed
- Product surface changed with supplier, label, dust, moisture, or oil
- Release air missing or late
Reverse-Trace / Ghost Busting™ Decision
if the vacuum-on command, release command, vacuum-proven bit, or transfer permissive is missing in live logic.
if the vacuum signal flickers, drops briefly, arrives late, or proves falsely inside a short transfer window.
Recipe / Health Log
Record the good, the bad, and the in-between: product, material, method, machine state, atmosphere, utility condition, settings, timing, symptom, corrective action, and result.

Walt says STOP! - Safety First
Make these checks prior to proceeding.
Stop and follow site procedures when dropped parts can injure people, robot/gantry/transfer motion can restart, hands enter pick/place/crush zones, or vacuum holds overhead or unstable loads.
