3D Printer Babbling
Keeping the plastic adhering to the bed and itself is a balancing act. I favour PETG filament: recyclable, no fumes. This particular batch enters 'glass' phase around 230-240C, so I print at 235 and start the bed at 70, dropping to 50 once a few layers are down - I want to keep the print cooling evenly, not melt it into a blobby mess.
About the first mm of plastic is down here on a piece that takes up most of my bed's footprint.
