I’m getting a rattle on my MPSM, and it only seems to happen when it’s printing on the right side of the bed. See my video:

Can anyone help me assess why this is happening and how to fix it?

2

Perhaps it could be the bearings??

3

Forgot to mention, did u try oiling it up to see if that fixes it ?

It is just loose/unstable Z rods can be fixed by tightening the z axis rods or adding stabilizers like the ones here. Monoprice Select Mini Z-Axis Rod Stabilizers by USWaterRockets - Thingiverse

I have the Maker Select (Not the mini), but I had similar problems when my bearings went bad. After replacing the noisy hearing, I inspected the original one to find broken balls and somewhat cheesy quality in general. Upon finding replacements readily available, it seems most are in a similar price range with a few on the expensive side. The cheap ones I purchased from amazon have lasted me fine so far. I did buy and use a bottle of tpfe gear lube that I also use often to ensure everything is well-lubricated. You might want to try this first, and then progress to the more involved steps. Of course, not too much with any lube and try to keep the bed moving after getting each bearing to ensure it gets in the cup and not just the rail.

I don’t even know what to oil up. Printer is brand new as of a few months ago and I’m pretty new to the scene as well so I don’t know where to begin.

It could also be your X Axis bracket (the black piece of metal covering the two rods going horisontal on which the print head moves left to right). You can find out wheither it is or not by holding the bracket on the right side or top (be gentle when applying pressure) while print is in progress Right side rattles more is because the print head is putting on some weight on that structure and it is further away from support, so it is either something loose inside of that metal tower or the bracket itself. Bracket is mounted with 4 screws, two on the right side and two on the left where it meets the printers frame… Could be the bearings too, just observe it for a while to understand where the noise is comming from. May have to tighten the screws, lubricate X-axis rods, print and install those Z-axis stabilisers (which will require unscrewing some screws and remembering where they go for later reassembly :slight_smile: would not hurt to replace bearings, but one thing you can do “for free” is to bring down your print speed to 35 mm/s and travel speed to 80-90 mm/s. They advertise printer is capable at 55 mm/s which is true, but you get better results at lower speed. Watched your video again it could be your print bed (Y-axis) rattling too due to bad bearings and little lubrication on the rods, but once again adjust those speeds…

Thanks for your reply. I’ll try your suggestions and report back. I’m normally not to worried about taking things apart, but for some reason I’m worried I’ll mess it up with this thing since I don’t have a video to reference on taking it apart. I’m a visual person.

Nonetheless, I’ll see what I can come up with.

As far as the print speeds, the MPSM only offers control in terms of 1.0 and increments or decrements of .1. I didn’t see anything about the mm/s. Need to do more research. Thanks again!

The mm/s is setup in Cura or any other software slicer you are using. And as far as taking stuff apart I somehow stumbled upon this gentleman’s videos - YouTube This is part one, unboxing which is probably irrelevant, but he has 7 or 8 other parts which helped me in taking mine apart. Videos are very detailed and slow-paced, may have to skip certain things… One more thing about apeed, you can set the multiplier to .6 or or even .5 on the printer may be .7

I saw those too. I will try and follow those.

If you haven’t resolved your problem, here is one thing you can check as well. Hold or place a finger on the cooling fan and see if the noise stops. I’ve found my cooling fan rattles the top sometimes, if I slightly adjust the cooling shroud it often stops making noise for a while. Seems like it needs a small isolation/vibration pad between the shroud and the aluminum heat sink but I’ve yet to bother with it. Let us know.
