Disassembly and assembly of parts on the same machine pallet

Hello,

I am working on a model with two parts (Part A & B) coming into the system on the same machine pallet.

Part A - Needs to move from the extension section of the pallet onto the main pallet

Part B - Needs to move to a buffer fixture and then move to the main pallet after Part A has been placed first

I am able to accomplish the movement of Part B from pallet to buffer and back to pallet, but unable to do so for Part A (move directly from pallet extension section to main pallet)

Any suggestions on how to resolve this issue?
