Latest progress on my build, and a warning to folks building their own. (lemmy.world)

Also got it belted up, but found out afterwards that I used a grease that is controversial on the rails (superlube with syncolor). It's recommended by LDO and Nero3D uses it in his video, but many folks on the Voron Discourse say it's a no-go. I'd rather not risk it, so I'm uninstalling the rails, cleaning/degreasing them, and reapplying some white lithium grease.

A list of gotchas is a great idea. Here are a few that got me:

  • sort your 16t and 20t pullies into two groups and separate them. It's easy to inadvertently grab the wrong one if you're not paying a ton of attention
  • space your z rails higher than the manual says. The only reason for mounting them super low is style points, but it makes installing the corner covers really hard. I had to loosen all my rails and work them up because they were too low initially
  • if you have a wiring harness and PCB anything, double check the pin to pin wiring against the PCB pinout. My hardness was not intended for the PCB XY endstop I printed, which caused some initial head scratching when the limit switches were behaving oddly
  • don't agonize too much over belt resonance
  • there is a slim model for the z-end stop I had to dig up as the one in the main repo didn't fit my build for some reason
  • you're probably going to print too many parts. This is ok
  • you're also probably going to print too few parts. This is also ok

Thanks for the tips!

For the z-rails, how high are we talking? Manual is 3mm and that's what I stuck with initially, but I've got the rails off to clean and degrease/regrease then right now, so now's as good a time as any

I'm currently at about 6mm. It does leave a gap, but it's really not noticeable if you're not at a super low angle and it makes installing the covers so much easier

Cool cool. I printed a shim to get the right height, I'll just make it a bit taller. Thanks again

If you have the printed parts already you can try installing one now to see how it goes, especially if you have the gantry off right now.
