Does anyne notice their M10 rod on Y-carriage start to rust?  

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

You on the coast? I know when I was in Hawaii, salt air shredded components.

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

Mine definitely has some light surface rust on it, and I'm in Philadelphia, which isn't particularly humid as far as places in the US go.

I'm not sure what the material is, but in many cases steels that are really stiff and strong (structural steel) are not stainless, and the stainless ones are not as well-suited for the purpose.

If you do scrape the rust off, a light machine oil applied with a clean cloth should help inhibit the rust.

Not near the coast, but saw some surface rust on the M10 rods. So I am just curious if any other users have the same issue on their MK2.

I'm in MInnesota - center of the continent, and not near any large bodies of water. It is fall now, humidity is decreasing, but today, with a bright light on the threaded rods, I did notice a little light surface rust. I don't intend to worry about it.

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

Oil the rods very lightly with a few drops of sewing machine oil (one or two) to eliminate rust. Peter( PJR ) disagrees with me on this, he has a dusty environment, I do not. He often disagrees with me, As I do with him.

Oiling the threaded rods is not an issue and doing so will help prevent surface rust although it won't cure it.

Personally, I don't see any sign of rusting on either Mk1 or Mk2; probably the atmospheric dust is soaking up the moisture in the air...

I also noticed some rather aggressive rusting on the threaded rods and I don't live in a humid area or near the coast.

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

I am in Bristol - UK and also noticed the rust after a few months 🙁

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

@carlos.b are you near the Bristol Channel? Is it seawater that far up or brackish? Strange channel , the Bristol Channel, with the largest tidle surge in the world I think. Dry air is the key for 3D printing at its best. Salt in the air will cause corrosion.

@matteo.s2 do you live in an area of high air pollution?

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

@Peter (PJR) I am not talking about a cure for rust. I am talking about prevention. You have said in the past

"Personally, I prefer to run the bearings dry because I have a dusty environment. But for some parts, I use light machine oil, silicon/PTFE grease and occasionally copper grease."

QED I am talking about prevention not cure for an environment. You do use lubricants.

Peter (PJR) another minus star for you.

When I had the rods in my hands for the first time I instantly thought "WHY?!?". I don't think that galvanized rods would cost that much more. The pricepoint in going stainless is much higher. I totally understand, why they didn't go stainless.

Meanwhile I bought stainless (1.4301 aka V2A aka AISI 304) threaded rods, nuts and washers for the M10 and M8 rods. I also ordered the IGUS linear bearings together with already from IGUS cut rods in stainless X90 aka 1.4112.

Sure this is some investment and we could discuss ages about the need of it. But I personally take it like that: If you do something, do it right the first time.
I do NOT have an issue when Prusa Research is shipping their printers/kits with the rods supplied. They work! Its more a question on what you want to pay for it by the end. Just to be said: Upgrading to stainless including going to all IGUS bearings costs me in Switzerland about 250€.
Is it worth it? Don't know! But I will never have to fiddle with rust or anything else with these rods. And thats whats it about FOR ME PERSONALLY. 😎

This printer is an open system and you can fiddle around with it as much as you like. Take the advantage and change the things you personally don't like. That's what I love the most in this system. It is not a closed system where you have to live with what has been provided. 😉

@matteo.s2 do you live in an area of high air pollution?

no, I wouldn't say so.

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

All I can say is change to stainless steel, M10 rods. I do not suffer from a rust issue. As regards environment, maybe a check of moisture and other air contaminants would be useful. I monitor weather at my site, posted on Wunderground, and I am currently researching an air contaminant monitor using an Arduino IOT or Raspberry PI with relevant sensors to cover most bases.

Re: Does anyne notice their M10 rod on Y-carriage start to rust?

it's more likely that we have different batches of rods. I don't think surface rust will be a big issue.
