Recently bought myself a second hand creator pro and just been printing benchmarks and little doodads to improve the printer. I've been trying to learn how to 3D print, and pretty much the only thing I've learned is that each print seems to require different settings! I'd been struggling a little with the first layer adhesion on PLA. I adopted what seems to be everyone's recommendations for first layer settings but wasn't having great success. First layer thickness was 0.4 mm to match nozzle width and an extrusion multiplier of 150%. This wasn't working, so I stuffed around a bit until I changed the thickness to 0.2 mm and all was well in the world again. I think there was just too much filament coming out and was ending up smooshing the extrusion against itself. Anyway, figured a general chat would be good instead of thread crapping the other 3d print threads.
