Purchased this to modify an extruder on an ARTME3D printer. Was thinking of swapping out the 3D printed gearbox. Ended up using it on a different project instead. Paired it with a DM556T driver, running at 24V, current set to 2.8A per the motor’s spec. It’s running a lift that raises a wheelchair into a pickup truck. Handles the load fine, no issues so far.
