⬢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
⬢3D printed parts are very precise, however, there still might be a tolerance in the printed part and same goes for the size of the nut.
⬢Therefore it might happen, that the nut won't fit easily in or might be falling out. Let's see, how to fix it:
⬢Nut won't fit in: use a screw with a thread along its entire length (typically: M3x10, M3x18) and screw it from the opposite side of the opening. While tightening the screw, the nut will be pulled in. Remove the screw afterwards.
⬢Nut keeps falling out: Use a piece of tape to fix the nut temporarily in place, as soon as you insert the screw in, you can remove the tape. Using glue isn't recommended as it can partly reach into the thread and you won't be able to tighten the screw properly.
⬢Every time we recommend to use the "screw pulling technique", you will be reminded with Joe's avatar ;)
⬢Building the MK3S printer is a challenge unlike any other and you should treat yourself for every milestone you reach. That is why a bag of Haribo Bears is included!
The biggest issue from the previous builds (MK3, MK2S) which we had to address was inadequate bear consumption. Many of you didn't have enough bears for all chapters, some even ate them all before they started!
⬢I'm glad to announce that after countless weeks of thorough scientific research (hundreds of eaten bears), we came to a solution!
⬢At the end of each chapter, you will be told a specific amount of bears to consume.
⬢Eating more or less bears than prescribed in the manual might lead to fatigue or nausea. Please consult a professional in the closest candy store.
Hide the Haribo for now! From our experience an unattended bag with sweets tends to suddenly disappear. We are still investigating this phenomenon.
To successfully finish the assembly please follow all these:
⬢Always read all the instructions at current step first, it will help you to understand, what you need to do. Don't cut or trim unless you are told to!!!
⬢Don't follow pictures only! It is not enough, the written instructions are as brief as they could be. Read them.
⬢Read the comments from the other users, they are great source of ideas. We read them too and based on your feedback improve the manual and the entire assembly.
⬢Use a reasonable force, the printed parts are tough, but not unbreakable. If it doesn't fit, check your approach twice.
⬢Eat the gummy bears as instructed! Disobedience won't be tolerated :D
⬢Most important: Enjoy the build, have fun. Cooperate with your kids, friends or partners. However, we take no responsibility for possible fights ;)
⬢READY? You can start by assembling Y-axis in the next chapter - 2. Y-axis assembly
