I’m issues with a print in that every layer after the first layer gets more and more bumpy. The first layer is perfect, then it starts getting very rough and bumpy. If I raise the z calibration, then it’s stringy and too high. I’ve played with nozzle temp as well as head bed temp. I’ve reduced the flow from 1.1 to .85.
I believe the nozzle is causing this (as if it was too low) but raising it avoids “bumps” but causes other issues. I have also ensure I cleaned it repeatedly with Alcohol. Any ideas?!
Thanks for the response! I didn’t change the fan but tested that and had no effect. What makes this more frustrating is that when I use the gcode samples that came with it, I don’t have this issue. But if I make pretty much anything with Slic3r, it has this same messy effect. I’ve looked at the codes and couldn’t see any difference in the settings. This is driving me nuts!
Here is a gcode from the sample which prints flawlessly for me.

Well after I determined the samples printed great, but the gcodes from Slic3r were not, I tried a couple other slicers and did not have the same issues as with Slic3r. I deleted all the profiles and started fresh and by ensuring I didn’t tweak anything at all, the prints seem to be working well now. I still don’t know what caused the issue as I analyzed the gcodes against each other, but at this point I’m just happy it’s printing successfully.
