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).
Not at all, that’s part of the reason for this post. I did give all the screws a once over and everything is nice and tight. The tool head was completely rebuilt between the first and second cubes. I’m on team kicky and it’s been pretty reliable/repeatable.
Does your x-axis have any play at all? Try to pull forward/backward on your (cold!!) nozzle lightly and see if it moves, it should not.
It did somewhere along the lines due to my hot end shaking itself apart, but I fixed that before attempting the cube on the left. There’s maybe a small reduction in ringing, but homing is a whole lot more consistent now.
