PCTG on Elegoo Neptune 4 pro issues
I got my first 3D printer (an Elegoo Neptune 4 pro) in February and have had a pretty good experience printing PLA.
Next I've wanted to try PETG and PTCG and I'm struggling with getting the settings right.
The images show my attempt to print a gridfinity bin in 3DJake's transparent PCTG, and it shows a bunch of the issues I've had in various prints.
First, the walls sometimes get holes in them, which is extra obvious when I run an orcaslicer calibration that runs in vase mode, they always have at least on hole.
Second, I have a lot of stringing, which often gets burnt.
And third, most walls have the same semi-translucent white color, but some of them get a bit glossier in certain parts, and the gloss has a wave-like pattern to it.
None of the images show this well.
Anybody knows what's going on?
