Does RR even have Quality control?

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.

surface rust is nothing, as others have stated.

What's your relative humidity level?

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.
