I am attempting to print a model that is too tall to print up-right and it has a large flat side that would be my first layer but ultimately would be the side of the object and I'd like it to look presentable. I'm using wood PLA, so I intend to sand and stain it.
I've had no issues with adhesion when using a raft. The slicer lays down a thick first layer that sticks beautifully. Here's the first layer of a raft - nice thick lines:
But when I try printing without the raft (even when using a brim) that first layer is not only thin, but easily moves away. Also the lines meld together creating gaps in the layer. And that's no skirt around the outside, that's the side of the model that doesn't touch the fill. I have to imagine this would be awful rough and impossible to sand out if it finished.
By the second layer, the friction is picking up the first layer and it catches the extruder and bam:
I've done some research suggesting higher temps, both of the extruder and the plate. I did see an improvement in the lines, but it still doesn't stick well. And what is considered a good temp? how do you know if you went too hot?
Any recommended settings in the slicer to make the bottom layer smoother?
