Repeatability starts before the glue path
If the workholding or reference structure moves, dispensing consistency is already compromised. Stable positioning and repeatable part reference are part of the dispensing process itself.

What Gets Missed Most in Dispensing Process Control Projects
Dispensing projects are often judged by valve selection alone. Publicly, that sounds simple. In delivery, the real project boundary usually sits in fixture repeatability, consistency control, inspection logic, and exception handling.
Inspection should close the loop
Dispensing control becomes much stronger when it includes inspection feedback instead of relying only on commanded volume or motion path assumptions.
Takt and process stability must be judged together
A project that meets takt but introduces unstable material behavior is not actually healthy. The better route balances takt, process consistency, maintenance logic, and acceptable recovery paths.
