While I acknowledge the expectations Ellis tries to set, all the youtubers out there have me chasing a dragon looking for better and better layer aliment on my z-axis. I suspect (at least) one of you will come out of the woodwork and say your printer has better aligned layers than mine too 😭 I'm certainly not alone, but even in that thread you can find some people claiming that not everyone experiences the issue
So far, I've been through three iterations on my CW2:
- BMG gears with a grub screw
- BMG Integrated Drive Gear Assembly (IDGA). Press fit gear = no more grub screw
- FYSETC CNC Pom w/ Helical gears, since evidently the BMG gears can still be somewhat offset
Results below with me hand holding my cellphone and moving a Pixar style desk lamp to be at a progressively steeper angle to the face of the cubes. Left = FYSTEC Pom (I also used Orcaslicer), middle = BMG IDGA, right = 'normal' BMGs. Note that the cubes are upside down.
Vanity shot with very soft and indirect light
Direct light, 90 degrees to the face of the cubes (basically perpendicular)
Direct light, ~45 degrees to the face of the cubes
Direct light, ~5 degrees to the face of the cubes (basically parallel)
At this point, I am going to shrug, give up, and print with fuzz (or avoid harsh light).
Thank you for the more detailed reply. The part in question is is a Voron Design Cube. I printed it on my 350mm Voron 2.4. The print does match the source STL fairly well, but it does look like OrcaSlicer's result (blue) has more corner rounding than the SuperSlicer results. There's a 45 degree chamfer on both the lower and upper face of the Z, which might contribute to what you're seeing. The parts themselves are also physically not that large, so you might be seeing a bit of the impact of the nozzle being round too.
