Re: better heated bed for SD4?

Glass and Hairspray all day long...If I think a print will give me trouble, I might use brim and glue stick the edges, but that's rare.

Height was about 1.5" with 40% infill; 3 perimeters.

SD2 - Stock - Enclosure - Heated Bed - Glass Plate - Auto Fire Extinguisher
Ord Bot Hadron - RAMPS 1.4 - Bulldog XL - E3D v6 - 10" x 10" PCB Heated Build w/SSR - Glass Plate
Thanks for All of Your Help!

Re: better heated bed for SD4?

Yup - Glass+Hairspray.  Glue stick works, too, but I find hairspray is more consistent and easier.  The moment of nirvana came for me when I discovered the "First Layer" modifier to the extrusion width in the advanced settings.  150% is about perfect.  For large prints that will tend to lift at the corners, I go to 200% and add a brim but that often pulls chips out of the glass with the part when I remove it.  At settings over 100%, this makes slicer print wider tracks for the first layer which really helps it get a grip.
