Hello everyone,
I recently got a CR-10 S4 back up and running, equipped with a BLTouch. I flashed the correct firmware and calibrated the nozzle height.
I designed a simple test part in SketchUp: a 30x30 mm rectangle, 3 mm thick, with four 4 mm holes, making sure the mesh was solid. I then sliced it using Creality Slicer (4.8) to generate the G-code.
The print went well overall, and dimensions are spot on. However, I am facing a specific issue with the outer borders: the outer vertical walls do not fuse or bond together, while the interior infill (set to 100%) is dense and solid. The perimeter walls separate easily, behaving like the pages of a book.

Here are my print settings:
-
Filament: PLA, 1.75 mm
-
Bed temperature: 50 °C
-
Nozzle temperature: 200 °C
-
Ambient temperature: 12 °C
Does anyone have an idea what could be causing this wall separation, and how to fix it? Thanks in advance for your help.
