Loud Vibrations
Hey All,
I recently completed my build of a MK2s kit and I have noticed a I get a fair amount of vibrational noise when the build plate is in the most rear position. It only seems to happen on very fast jerky movements like when the printer does the initial bed leveling set up for the 9 points. I do have Misumi rods and bearings installed and I did check before I installed the y-axis belt to see if everything slide through the entire y motion easily which it did. I have also double checked to see if my rods are 178mm from edge to edge near the y-axis mountain points. I will try and take a video this evening to see if I can record the noise. I don't have the noise when the build plate is in the most forward position. I also haven't had any issues printing high quality prints so it doesn't appear to be affecting build quality.
Thanks!

Just built mine last week and have the same issue. Sounds loud and rattly at the back, especially during the slow XYZ calibration moves. Hasn't caused any print problems however.

Hello Gents;
There is a start of a vibration discussion here on our forums;
I recently used the great input there to trouble shoot my own vibration issue, with success. Let me repost my find here;

Hello All;
First a thank you to all who post answers and suggestions here, in the forums in general and this thread in particular, it is always appreciated. I have solved a few problems on my kit built i3 MK2 with the aid of this forum and I must say I have not said thank you enough.
I have been a on a kill the dam rattle search for a few weeks now and have finally landed on my particular solution. With the belts squared up, the frames parallel, the bearings confirmed OK and the Z axis threaded rod holders checked I still had a rattle.
For me it was on the underside of the bed, the two screws that hold the Y drive belt to the bottom of the bed. The orange piece that holds the ends of the belt and attaches by these two screws to the bottom of the bed had worked loose. They are not readily visible when you invert the printer as they are covered by the belts. Easy enough to move to check but I had missed it on my inspections. :geek:
The quick X and sometimes Y movements would create the rattle and the bed seemed amplify it like a drum skin. The movement when I found it was very little, maybe 0.25mm but is was enough to create an irritating rattle.
Maybe, just maybe I should put away the small crafting hammer and remove my prints more gently? 😯
cheers all
Hope that helps get you started.
