I recently did an uninstall reinstall of Labview 6.0, Flexmotion 5.1.1. and MAX 2.1 All worked fine before the un-re install with the exception of a new PCI 6034. An overzelous systems person did the un-re-install in the thought that the board would work. MANY things have not worked since...one by one I've tracked them down, but this item leaves me at a loss. I load a program onto the 7433 board, I load a motion profile into memory, I execute the program and wait in a while loop for a Motion Complete Flag to become true. In normal program mode the Motion complete flag is NEVER false and the while loop ends before the motor moves. In debug mode the Motion Complete flag IS false at the start of motion and the move works correctly. Nothing in the onboard program, the move profile, or the execution command-wait for flag has been changed. What could possibly be different?-- Jim Fee
