Printer bolts dont have any locking compound so sooner or later they get loose. Those two bolts in the middle of picture under, which keep the y-moving plate and belt "block" together, got loose in my printer. One print got funny looking becose of maybe 2mm looseness of y-moving. So I locked the bolts with locking glue. It was quite annoying to try to get nuts back with out dissembling much. They could lock the bolts in the factory..  |

You have to be careful with threadlocker as it can damage some materials like plastic and might make it nearly impossible to take parts apart later. I had my bed off and I instinctively tightened all the nuts and bolts, there have been many reports of loose bolts so I just assumed I needed to check everything as I come across it. Did yours come loose or were they already loose and took a while for you to notice, did they loosen off again once tightened? It might be a good idea to replace all the nuts with nylock nuts, that way at least they won't fall off.  |

Changing nylocs at least in the essential places is sertainly good idea. To tighten those bolts the hot bed needs to be taken off (or have some special tools maybe) and it's impossible to say how often you need to do that. Just that normal nuts without any locking in this kind of use is just bad idea..
I tighten the bolts when I got the printer but of course should have done that often (well I have printed just little things mostly test pieces, not much anyway).

Yes good idea, I will check my often until I change the bolts, thanks.

Hey guys, there are a lot of low end vibrations associated with 3d Printers of all descriptions, so this is a common problem, it is good practice to regularly check all nuts and bolts as well as calibrations as part of a regular maintenance program. I know this all sound pedantic, but maintenance extends the life of all equipment of any kind.
I personally have electronic gear that I have had since the dark age of 1978, and with a little regular maintenance it is still going strong after almost 40 years, oops there goes my age again.
Nyloc nuts are a good option, or the old school way is two nuts, locking against each other, or anti shake washers would be a good option for this unit as they are designed to handle extreme vibration. 3dprintingmeatheads foam option is a great way of reducing vibration caused by resonance and will help reduce vibrations. So there's my take on this issue anyways.
