Daan, Great idea unless you clean in my favorite machine. SmartSonic takes the fillings out of your teeth when walking by in operation as well as any epoxy fids or epoxy anywhere on the stencil. Wonder why it works so well! Have to use sharpy (how's that spelled) to rejuvinate the black stuff in fid holes for proper recognition. Did try nitrite and other blackening stuff. Need ideas on this as well. Also Daan, downloaded the SPC thing. Too long out of dos. What is the startup thing required to activate the program?
