Back in the early 90's I moved to The Netherlands and worked for a company that cut and bent the leads on semiconductor lead frames. I was responsible for the pocket tray loaders and off-loaders. My first introduction to CAN bus before CAN even had network specific bus drivers. There were no High Level Protocols. Lots of pneumatics, ,Compumotor linear stepper motors, sensors etc.
The flywheel on the 30 ton press had an absolute encoder and particular positions caused things to move in and out of the way of the press tool and die. They are having a 30 year reunion for the introduction of the TFM this fall. Unfortunately because of COVID rules I won't be able to attend.
