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).
It may be a trick of the lighting. The picture you added looks much better. But I wouldn’t think you would be able to see that kind of errors just from light.
I’ll dig out some old prints tomorrow and see what they look like under a direct harsh light source. I say old because as soon as I started modding my printer, the quality went to shit. I may be able to print TPU and ABS now, but it definitely doesn’t look as good as before I started messing with it.
Haha, sounds like fun. This is a Voron 2.4 350, so it has the (dis)advantages of being big/having long belts and having a hot end that’s biased toward speed. I’ve run a spool of TPU through it somewhat recently and at this point I basically daily ASA. PETG parts look better, but I have not tried a PETG cube yet. Maybe I should.
Thanks for digging around for pics! I appreciate the reference.
