EDGE: Scrub Plate Spacer
The scrub plate spacer is a metal plate that goes under the scrub plate. This part replaces the stack of washers and washer-retaining o-rings.
- Makes it easier to remove the scrub plate - you don't have to keep the washers on the screws, or chase the washers around if they fall off.
- Makes the nozzle offset calibration more consistent - we've removed compliance (the rubber o-rings) from the system, made the height more consistent (plate vs washers), and better supported the scrub plate so it doesn't tilt when force is applied.
