    Anyone know why the preset had just stopped operating? You can speed the press up manually and it’ll stay there, but won’t come up to speed after pressing the production activation button.

    Assuming it’s pre-CPTRONIC, it’ll likely be an issue in the commutator servo drive. Possibly a loose solenoid in the latching mechanism, or even a bad solenoid. It’s all under the rectangular cover on the main drive.
