So, I've done my first two prints with PETG. I've already learned a few things. I went in increasing the Z Offset, raising the temps (extruder, bed), turning the fan down and have gotten successful(-ish) prints. What seems to be the case is that I need more top layers because with what I was using, I got a lot of pillows and zits on the top surface corresponding to the infill gaps. Also stringing, even though I was using a pretty low (220C) extrusion temperature. Using samples of semi-transparent rigid.ink filament, the prints themselves seem mostly sound, but look like hell. I do like the fact that while I get decent first layer adhesion, unlike PLA, after I remove the item from the bed, I don't have to walk around the room to find it. In any case, if anyone has tips, pointers and/or example settings for S3D, it'd be much appreciated.
