Missing balls from Y bearings MK2S
Hello,
I assemble all the kit by myself, with patience and slowly, when i assemble the X some balls come off from the bearnings, if i shake the bearings i can hear the balls shaking, if i do samething on Y bearnings nothing move or do noise (Only X bearings come with outside balls) so i continue assemble to test if it will affect anything.
Now printer is completed and it print very good (at least i think, my first 3d printer...) quality is very good, still i like to ask if it can affect the performance and if can be improved. Also if i apply little force to bed at a corner for example bottom left and push right, bed move horizontal about 1 to 3mm. When priting it only move up and down, this only happen if i apply force by the side corner, i like to know if that is normal or my mistake?

Re: Missing balls from Y bearings MK2S
Personally, i'd replace them. Ball bearings that are losing balls are broken. Depending how many balls got lost in a single bearing, it might work ok for a while, but in the long run this is not worth it, especially considering how cheap they are on ebay & co.

Thank you, i may do that, better replace than sorry.
Also can you tell me if bed moving horizontal is normal when pushed?
About print quality is it OK?
Regards
Re: Missing balls from Y bearings MK2S
Well, my printer arrived with broken bearings as well, so I am not sure what is to be considered normal. My bed was "moving" a bit as well when pushed.
Your batman, bottle opener, marvins, frog and lamp shade are looking pretty good. So i guess it's safe to say you / your printer seems to be doing just fine. The skull thing could do with a bit of tweaking i guess (i never printed that one so i don't know for sure).

Thank you for reviewing.
Almost all was printed with -600 live z, vase and other prints with -800. I didn't notice a big change in quality but -800 seens to give best quality and more hard to remove prints from bed.
I also have other problem when printing ABS, PLA and PETG print well with this settings but not ABS, it start to warp at 2nd layer, with -1000 works but noozle will touch the bed.
34ºc ambient temperature, no ACs or other ventilations.
I use Prusa EasyABS fillament

just to make that point clear: beside the admins like josefprusa and jakub.d, none of us at this board is a member of prusa. the only relationship we have to prusa is that we like their printers. most of us are customers and as far as i can see, most of us are convinced that the i3 mk2(s) provides the best value for money ratio at it's price segment.

Well i think all foruns are like that, support is user to user and people may know that. Otherwise i would have contacted support directlly from their page. All my questions are redirected to comunity and how my printer compare with the others, and what i have ask also happen to others users.
Admins have more to do than anwser user questions and forum itself, for example improving the printer 🙂
