Eden , if you have camelot you can have a dual needle with preset foot relating you the exact separating height ; the placement force does not apply as far as I know . Picture basically two needles with a touch foot beside in calibrated offset . As you take off sideways , after dual dispense , you can not string into each pad . Contact Shaafi : [log in to unmask] he knows better than most , and can provide you with an actual custom solution . He would recommend you volume dispensed as well . They have a special kit for measuring the volume as well .
