Support material not touching object - Slic3r setting?

mine does that some. usually most makes contact but main thing is it keeps plastic from sagging while printing. once in a while that barely touching issue lets a small part like a wheel on small vehicle fall loose b4 its stuck to the rest of model. if Im watching print I have held it with tweezers till it is attached to model so it dont cause other holes/gaps. I dont like making support thicker for this as that makes for harder to clean off later. also for slight over hangs beyond support I have held a tool under it till plastic hardens (since no Gcode fan for such bridges) then it finishes layers on top fine. thats why a Gcode cooling fan at nozzle tip and duel extruders for wash off support material are my main wish list items for like an WB apprentice.

what about in slic3r config under the support tab at bottom where it says "interface pattern spacing" 0mm? maybe thats how much to add/reduce that layer size to make them closer

always wondered about that setting, thanks Ironman. the last setting you talked about determines how thin support material is compared to whats being extruded meaning at 0=default it will be same as perimeters on model making removal much harder without damaging model (as many parts are same size) from my own experience printing tiny detailed parts. also the guy whos models we are making gave those settings that he uses on his 'UP' printer to get good results on his 1:200 scale Military Armor models. if printing at least 2x larger and if you have all tools needed to very carefully remove support that may be OK but I have all hobby tools available the past 50 years plus hand made tools, dental etc and at scales smaller than 1:120th its near impossible damage free as small of space there is to work. most my vehicle models are 1:160th and some 1:220th and an hour is on the long side of a print this size so I have printer just above my laptop screen and can 'help' it along when needed while browsing.
