Just to clarify, you are talking about the inner black box not driving down and not the pneumatic function that brings the tactile assembly closer to the stencil? Sometimes the pneumatic shafts get slightly bent and the assembly will not retract. T

Don, either you have a faulty park sensor or much more likely the vision gantry Y axis is not reaching the sensor. Possible issues, one of the two VY drivers cards is failing; one of the VY forcer motors (air bearings) is failing; to much air leakin

Check/reseat all connections on axis driver card and from driver card to step motor. On older MpM's it is common to get a bad connection on the connector for axis driver power and blow components on your driver board. Reseating these connectors mig
