/diy/ - Do It Yourself

I'm trying to print ABS without an enclosure and have had little success. I've got a few prints to come out, but there was initially bed adhesion issues and then layer adhesion.

I cranked the bed up to 100, but now that my bed is seasoned it seems to stick fine at 82 C.

I printed a few test cubes and they werent bad, but had some splitting on the sides where the area pulled due to shrinking. I tweaked the settings and moved on to a real print: the leveler wheels. Now when I check on the printer instead of layer after layer of plastic, I get this weird sporadic crumbly plastic in the shape of what I want printed. The plastic is stuck to the bed, and the first few layers look fine, but then things get fucky. I printed a go pro mount that was an inch or so high, so I figured ambient temperature shouldn't an issue for these little wheels that aren't nearly as tall and have the radiant heat from the bed to keep them warm.

I occasionally hear a crack or a pop, but the filament is new. Before I go throwing my new ABS in the oven (is that even safe if I plan on using the oven for food later?) I thought I would post my settings.

Cooling is off
brim set to 5mm
all at once print, though it shouldnt matter because I've reduced the print down to a single object until I get things dialed in correctly.
