⬢The printer's package contains a lubricant, which is intended for maintenance. No need to use it now the bearings are lubricated. There is a dedicated online manual on how to clean the printer and apply the lubricant. See help.prusa3d.com/maintenance-tips
To everyone just starting out: The comments are a great place for additional information and the collective experiences of other builders. However, some comments are difficult to follow because of poorly written text. Please edit your comments before clicking submit. I have spent several hours reading through all the comments throughout this build and it's like reading through comments written by six year olds. It's not that difficult to read your text and correct mistakes before submitting. Also, I'm not referencing the broken English of non-native English speakers. I'm refering to the obvious native English speakers with horrible writing skills. Please take the time to make sure your comment makes sense before posting it. If the text is hard for you (the commenter) to read, just imagine how it's going to read for others; especially non-English speakers. When they translate your text, it's going to become gibberish. Perfect grammer and syntax isn't expected. Just make sure the text is legible before submitting. Thank you and enjoy the build.
I love the manual layout. It is easy to use. Good thing I am not color-blind or else things would get a little "wonky". Maybe also include letters (A, B, C, etc)?
Hello Lou. We have been dealing with this question for some time. But we still can't come up with an ideal way. Method A, B, and C, is good, but not always applicable. Anyway, we are open to every suggestion :)
For the love of God, Prusa, please disable the "magic search bar" on the build guide pages which appears every time you scroll up just a single line! I nearly pulled out all my hair* due to this alone. *Thankfully I'm already bald.
It's directly misleading to say all the required tools are provided but then depend on a permanent marker midway through assembly for bearing alignment. Most of the required tools are provided - please locate a marker etc. would not be so hard to say.
Not to play semantics, but the tools are provided, the marker is used as an indicator and is pretty much a common household item so that is why it is not included, there are other things that could be used since you are just marking a bearing.
While you probably could build the printer with the tools provided in the kit, several other tools will make the job easier: - Instead of using the needle-nose pliers to hold nuts while you try to tighten them, get a 5.5mm socket for your socket wrench, or get a 5.5mm crescent/box-end wrench. Either will be particularly useful for holding nuts under the Y-carriage when tightening the bolts holding down the bearing clips. (Don't overtighten the bearing clips; doing so can distort the bearing cases!) - The Allen keys provided by Prusa are OK, but a good set of metric ball-end Allen screwdrivers will make all your bolt-tightening--and there's a *lot* of it--go much faster. I bought a set from Bondhus, but there are many choices out there. - Channel-lock pliers can sometimes be very helpful when trying to, say, push a square nut into a slot. You might want to cushion the jaws to avoid scraping or breaking plastic parts. - The most helpful tool for ensuring that captured nuts are fully inserted has no name. It's a gadget roughly the size of a wood pencil, with a central, thin plastic handle from which protrudes a pointy metal rod with a conical taper to a sharp point. (There's a second, fatter metal rod on the other end, but it's not particularly useful when assembling the printer.) The conical end is ideal for grabbing the hole in the middle of a square nut that you've partially inserted in a slot, and then pushing that nut further into the slot. This tool came with my Weller soldering gun and is designed for use as a soldering aid. Fortunately, you don't have to buy a soldering gun to get one of these. You can find it as part of a kit of soldering aids; just search for "Weller solder aid tools" online. Seriously, this tool saved me an enormous amount of grief.
