Clicking sound

Hi All
I have had my MK2 for over a week now (kit) and everything is running perfect. I am very happy with machine and has printed everything i have put through it with ease. I am now getting a small clicking sound from the X axis motor or belt. Every is lined up and still running fine. There is no rhythm to the click. ??

Re: Clicking sound

The idler pully (shaft) screw does not evenly support the bearing, the threaded part is two long and causes the idler pulley to be aligned off centre so it rocks back an forth and knocks the plastic. Fix with a comply threaded screw or bolt with larger untreated (smooth) zone...

lossed the gear on the motor and moved it out a bit. Seems to have done the trick.

Re: Clicking sound

Hello, has anyone of you solved or found the cause of the noise? I'm facing the same issue, a clicking sound during the x axis movement (seems coming from the x motor).

Re: Clicking sound

Is there the same sound when doing 9-point Z calibration (before print)? If no, then clicking sound is side effect of mesh bed leveling working. 😉 When the extruder moves, Z axis changes position a bit, which can be heard as light clicking as Z motors do their steps.

Re: Clicking sound

I've been gradually locating and trying to resolve the various noises the mk2 makes, mostly with success. I too have this. Even on slow moves on small parts I'll often get it. It's either from the motor end or the idler end, depending on extruder position, and sounds like the belt teeth catching ever so slightly on pulley/idler.

I've come to the conclusion this is inevitable (it isn't possible to run the belt in the middle of the motor pulley or the idler, it will naturally move to one side). I've managed to improve things a lot by not pushing the belts fully into the extruder body, and basically getting the belt as straight as possible between motor, extruder and idler.

Re: Clicking sound

Tonight I'll try to loose the belt a bit, maybe is too tight and this clicking is coming from the motor itself (these are just assumptions).

Re: Clicking sound

This is very strange. I get the clicking noise on X movements as well. Especially when moving slowly (ie first layer).

So far, I have simply ignored it.

Re: Clicking sound

Do you have noise cancelling headphones, if so then:

Use a piece of tube and stick your headphone mic in it.
- Using the smartphone record a video
- Use the tube (hose from shop vac) with the headphone mic it to locate the clicking sound

Since the noise cancelling algorithm cannot filter out clicks, you may be able to home into the part that is making the sound.

This method is used to find engine problems on cars.

Your smart phone has some noise cancelling in it, but using a dedicated headphone like the Quiet Comforts by Bose really cuts out everything but sharp clicking noises.

To further exclude noise, you may consider the following.
- put the steppers in low power mode
- unload the filament
- print a job that use the full print bed and is only 2 layers on the z
- disconnect the cool end fan ( the big fan will not turn on until layer 2, but you can disable it in the slic3r)

To go one step further you could:
- Using the 2 layer print object, pause the print.
- remove the print bed
- restart the print

As well as my previous post. 😆
I bet it is the MBL.

Re: Clicking sound

Not with my printer; definitely only happening in X direction and from somewhere near the extruder assembly.

I suppose it could be a bearing.

Re: Clicking sound

MBL is an interesting idea. I definitely hear it on mine at the idler or motor ends, so am still fairly sure it's belt teeth noise. However, Z adjustments would transfer vibration there... I'll keep that in mind in case I decide not to ignore it in future.

I'll be keeping an eye on the results of this test though. Let us know what you find.

Re: Clicking sound

Sorry for the newbie question, but what does MBL stand for??

Mesh bed level?

Thanks

Re: Clicking sound

Are you guys using the default spool holder? The filament unwinding will make a click if the spool is under tensions.

Yes, but it's not the same as the one you are using, so that theory is out the window...

Re: Clicking sound

Does your MK2 have the default wire wrap setup or cable chains?

Re: Clicking sound

I have seen this and found it to be a case of the toothed pulley and the belt. If the belt and X axis is very slightly skewed, the teeth of the belt can catch on the pulley when the belt is pushing hard against the pulley that is attached to the Stepper. If you put your ear very close (watch your ear though), you will hear it coming from there on the X movements. I checked the X axis components and it went
