Topic: Layer height / print result

I have new SD3 (about 1 week old).
I face serious sticking problem with this printer, but I think I solve those with forum help. thx for that.
Now seems my layer heigth is wrong because printhead poking print result continously.
I use Slick3r to slice model, but I couldn't realize what settings I need to change.
I try to change layer height but it seems change amount of material also.
I print thingiverse thing:38064 without in infill (Only infill when needed set on) and print result start look OK after 6 - 8 layer.
Possible reason could be wrong Z height but if I change that ABS not stick at all.
I already tried glass bed with hairspray and ABS glue, but then I couldn't print even first layer.

Weird glass/hairspray is very grippy. Maybe you use to much hairspray?? Or maybe slow down the speed of your first layer that might help.

Re: Layer height / print result

I try both much and little bit less (sprayed to clear and mat) result was same.
Weird thing was in printer when glass was heated I couldn't see hairspray at all.
Could it evaporate because of heated printbed.

I currently blame Glass temperature even I let it warm like 30 min before print.
I measure Glassbed surface temperature with touch temperaturemeter and it shows 67 C after 5 min (settings was 95 C).

How ever I get ABS to stick for Kaption on original bed.
Now problem is that "over" filling and bending.
Bending I thing can be handled with casing, but what could be solution for first layers over filling?
