Topic: Take a look at this bottom layer problem please.

Still limping along with my old extruder waiting on the E3D. My ABS bottom layer is real loose. In the pics maybe you can see that the infill is not physically connecting with the perimeters. when I turn the finished part over, the bottom is real coarse fill and has threads flying loose.

My corners are also lifting, despite 200C extruder temp, copious use of hair spray on glass, 100C bed temp and long warm up waits.

I have Searched here for a solution and piddled with various Slicer settings but, no cigar. Help please. Thanks.

Have you tried a little hotter on the extruder??? especially if it's black filament. Does the filament extrude free and straight while extruding in midair?

Yes, it looks fine. I'm at 200C now, I figure if I go much higher, it will trip off. Plus, would that explain why the filler isn't extending all the way to the perimeter? I think it the two would meet, they would bond. Of course, that still leaves open the very coarse texture of that bottom payer, which is exposed in my part.

Bingo, Manx! You win the prize. Thanks. God, I'll be glad when I grow up and don't have to ask so damn many dumb questions. But, I'm learning. I appreciate your time.
