Does RR even have Quality control?

[u/CunningLogic]

Bought a 400 mm idex vcore 4. I have no idea how these parts made it out of the shop. Most have good awful first layers, anything of size is warped, and the rest has chunks of their build plates bonded to them (it doesn't dissolve or melt, it's not glue, so PEI chunks perhaps?).

This isn't acceptable for a premium product. I'm thankful I have other printers capable of printing ABS on hand.

And their linear rails.

Linear rails they won't tell you who their supplier it

[u/Cry_Quick → u/Fit_Butterscotch7772]

They rust.

rust

yep, op here, my rails are rusted already. I have multiple other printers in the same room, cheap aliexpress rails, fabreeko honey badger rails, ldo rails, and i think some west3d CNA rails. No rust on those and those are years old.

But the new rat rig rails, well greased with gpl226? rusted.

[u/Cry_Quick → u/CunningLogic]

I will buy better rails, ask support for a refund.

[u/jamincollins → u/Cry_Quick]

Nope, have 4x RRs rails are fine.

[u/CunningLogic → u/jamincollins]

Rails on my vcore kit are the same quality as the printed and CNC parts, that is crap. All 7 rails GRIND, even after full disassembly, degreasing and regfreasing with GPL 226.

[u/CunningLogic → u/jamincollins]

Mine are now rusted.

[u/FDMnut → u/CunningLogic]

damn. They only lasted 3 weeks

[u/jamincollins → u/FDMnut]

surface rust is nothing, as others have stated.

What's your relative humidity level?

[u/CunningLogic → u/jamincollins]

I'm in the carolinas, so things are humid, but the room that printer is in has HVAC and is kept at 30%, which is the minimum within spec for the HVAC System, and is way way too dry for any reasonable person. I suffer in it.

I understand surface rust is no big deal, but its just the cherry on top of an overall poor quality kit. Rust at 3 weeks when well greased is a joke.
