/diy/ - Do It Yourself

oi plastic fags
my printer is not behaving lately
i have a heavily modded ender 3 with a sprite extruder

i have issues with the exterior walls not being smooth (a cylinder) and some kind of weird issue with layers (see picrel)

the print broke, suggesting bad layer adhesion, but at the break point, the lower layer is looking great, but to upper layer looks like shit

it seems to correlate with the feature inside the cylinder

any ideas ? ive ran some calibration tests, every one is coming out clean, and most of my prints looks alright
im a bit at a loss here, any idea would be appreciated
