So I found a loose screw underneath my printbed of my Core one L, not sure where it came from and I've checked all the places that use the same type of screws but nothing to be found there.. if anyone has suggestions on where to look it would be greatly appreciated!

Since It has the little edge just like the ones on the Z screw I thought that would be it. But after checking all 3 of them and seeing that all of them were just in place, I'm left wondering where this little thingy is supposed to go haha. Since it was on the backside of the printbed I can only assume it's from somewhere in the back of the printer, or the extruder assembly. Yet in both places have I found well, nothing.. which is good if you look at it that way, but I'm getting paranoid that something is hanging about loose without me knowing. Could it be a screw that the lovely person at prusa dropped and never found again, or am I missing some hidden spot?

I've put photos of the screw, place of finding and possible places It could've been!

So another quick question, I've basically used the same type of lubricant for all my printers and it has always worked really well. Now the Core one L is a bit more expensive than my other printers, so I'm not taking a guess without asking for some advice from some of you guys since some of you will definitely know more about it than me.

I've used Mobil EP2 Grease on my other printers for the smooth rods specifically, and for linear rails on my K2 Plus. All machines that I used run very well on this stuff. So is this something I could use in my Core one L aswell? Or is it better to stick to a different form of lube? (Recommendations are welcome) Just trying to figure out if this is stuff will be good for the my newest machine in the arsenal :)

After some initial issues with the Core one L regarding unusual noises, nozzle clogs and some loose screws. I can finally say that it's running smooth like butter! It produces great quality results which I'm very happy about, and the fact that I could fix anything myself if necessary is a huge win if you compare it to for instance Creality or Bambu Support waiting times lol.

I do highly believe that someone has placed a curse on me though, every printer I've had had issues in the first 2/3 days. And once those initial issues are solved, I'm not having issues anymore. For instance the K2 Plus Combo I have, in the beginning I was thinking about throwing it down the balcony because of all the issues I was having, from loose screws to a deformed Z Screw and a bed mesh the shape of a taco. And after those were fixed, I've had 0 issues for nearly a year. And that goes for basically all printers I've had.

So to the one who placed this curse on me, for the love of god, release me lol!

Anyway, great printer, great community and great customer support. I'm a happy man :)

Many thanks to all those who gave suggestions on my issues with harsh sounding travel moves on my new Core One L. After going through the potential solutions, I found that the issue was laying in the Y axis bracket alignment. After loosening the brackets on both sides and gradually tightening them the scraping/metallic sound disappeared completely. In the video I added you can see how it sounds and looks now, it goes much smoother than before and make a lot less rattling noise. I will put a picture in the comments in the brackets I'm talking about for future reference in case anyone else is experiencing the same issue as me! And again many thanks to you all. I've joined the community only since yesterday and the help was unparalleled to what I've had before in communities. Glad to be a part of it!

Hey Guys, so I just received my Core One L, and I'm running some tests. And during this one I noticed a sound I was unsure about and would love to hear if this is me being paranoid or something else lol

It's about the long travel moves at the end, it sounds like something metallic is screeching or rattling, but I'm unsure if this is normal or not. I've done the belt Tension, input shapers and phase stepping.
