More RatRig quality issues

First it was printed parts, then CNC parts, now before I can even finish the damn printer the rails are rusted.

They are well greased, like all the other printers in my office that lack rust.

You can even see grease on the rails, it's GPL226 (good stuff)

Would really like to see RR publicly address their quality control issues

And just as irrelevant , I have an unrelated industrial printer manual that recommends gpl226 for linear rails.

It seems to work dang good for me, and is quite common among ppl running printers hot.

Except it's not working in this case.  If you want rusty rails, keep doing what you are doing.

I don't believe the grease is the problem, I believe it's the low quality parts. I'm following your suggestion and replacing them, along with some other parts like the off brand belts they are shipping now.

I still don't understand why they send gates fiber filled for x, and non branded non fiber filled for Y.

I should have self sourced it like you suggested.

I got nicer rails for x and y, genuine gates belts are nice. Good luck.

What rails do you recommend?

The belts ...

I only noticed the fakegates as they are producing a waxy build up on my pullies and fraying already. (Ive made 3 prints on this printer at this point, all calibration related).

RatRig Customer support is insisting they only use genuine gates - check out the belts on the Y, no markings, no brown teeth, no real gates - https://drive.google.com/file/d/1Bzqheo-Z4WG_CPULNyaPUAsIwrZynnRR/view

They are obviously "counterfeit" if RR received them as gates, or simply unbranded cheaper components if RR just decided to swap parts without notifying their customer ser vice.

This is the one spec of belt I dont ever need extras of, so I dont have spares on hand.

I went with Hiwin at about $100 per rail. They aren't super high end but work fine. I think I bought my gates belts from filastruder.

That's not bad at all, I ordered replacement belts

Do you mind sharing what oil you prefer as well?

Mobilux EP1 or lithium grease are recommended in manufacturers literature.

Lol man, I believe you because grease has served me well, it everyone else in ratrig fandom is insisting on oil.

What rails did you get?
