Update: Issue fixed, unfortunately the emails exchanged are confidential so I can not distribute the information of what the issue might/was of been.

I'll update on this I have contacted my reseller and they are going to organise a pickup of the printer to get it checked out as it's still in the Australian 1 year warranty period. I'll update again when more information comes in.

Really thinking it has to do with something in the head here is anther video. If I just touch anywhere on top of the head while printing noise goes away. https://www.youtube.com/watch?v=3OoXPhnS_z8

Had a good look and none of the belts contact the blocks. Starting to think maybe its a bearing :(as nothing looks like its coming into contact and none of the belts look like there slipping. going over my videos with this one I was stumped as to why holding the fan mount stopped the sound, it looks like there is some slack with the shaft and the bearing and makes like a clicking sound. like the slack/play is a 45 degree angle movement on the Y shaft at the head.

While moving the head i can't see the belt slip when it makes the noise.

Hope these are okay. https://drive.google.com/open?id=1rgZdoCKJgimObnHyJ8yhcrkHDzZtKfulGw https://drive.google.com/open?id=1inyhBW-D2nroGJPyGm0DXl-jjWmQMg7jjQ https://drive.google.com/open?id=1TseGaP785_Hpr75Xh474cfhHMwGOBntYRg https://drive.google.com/open?id=1Hmlo9FUOUi06xLUFTe2_8-7SFRVQR2icyw https://drive.google.com/open?id=17cPiP58_QVoOn9GQs8owFoNQwGPt6ehlFQ https://drive.google.com/open?id=1ClMsKBYlHXHDWtAIqwr0pvE_vJtC5w7SDg

Okay was in the process on putting an a differnt fan mount and well we can rule that out still makes the sound even with the fan mount off https://www.youtube.com/watch?v=GUSFoQgey3A just tried pushing the belt sideways while moving the head the rattle/grind is still there.

I might give it ago (just putting the fan-mount on) can't hurt the worst that can happen is I put the original one back on. Also want to thank you so much for your time in replying to my topics. No problem I try to help, I always learn something out of it Btw, just to be sure sure... Since you hold the fancap when it moves, maybe the sound comes from the linear bearings? Just to be sure before you disassemble anything Anyhow, if bending a bit the metal fix it, at least you know that the issue is that and nothing else. Cheers! bending the bit of metal did not fix it but doing a axis alignment (still might not be perfect as getting to some of the grub screws was a pain as I could not get both to show with the tool clicked in) reduced the rattle heaps. Is there an easy way of checking the linear bearings to be sure its not them.

Thanks I'll have a look at that one. https://www.youmagine.com/designs/fan-mount-um2-olsson-block I also found this one but in the comments it says to run PID autotune do you think it would really be necessary to do so?

I have managed to reduce the rattle by following this, it's not fully gone but no where as loud as it was, https://ultimaker.com/en/community/39491-very-challenging-gaps-between-infill-and-outline-solving#reply-175237 It was a real challenge doing it as one side grub screw would show but not the other but got there in the end and it must of needed doing as moving the head back to front its so much smoother now.

if I can not work it out can you recommend a printable fan mount?

Okay when I was getting the photo's while moving the head I found this. I was very careful when moving the head by holding the fan cover it would not rattling.

Is it best to hold off on printing until I find out where the noise is coming from or would it not really be hurting anything.

I oiled them lastnight when I noticed the sound, and was oiled about a month before that. (only only done about 20 hours of printing in that time had a slow month) The wiring for the end stops is not touching the belt. Moved the head to the middle the moved it to the left a little and measured from the thin to the thick shaft and its only about 0.2mm different from front to back and the same on the right side.

I done an atomic pull and then took the TFM out and put it back in and it got closer right on 16.9 and the screws are tight. and there is no leaks and filament seems to flow out nicely.

It's close on the left side but not touching

I need help, My printer has started to make this rattle type sound on the Y axis. can only hear if the movement is slow-ish can not hear it when it's printing at 40mm/s +. https://www.youtube.com/watch?v=jG94XJy4WJ0 With the printer turned off if you slowly move the print head from back to front you can hear it plus it feel not as small as moving the head side to side. like it feels more steppy if that makes sense, I have put some sewing machine oil on the rods with no improvement. Here is some photo's of the print it does not look like quality has gone down, well on the cura fast setting for PLA its gotten a little more ringing but it has always been like that from day one but don't think as bad. 40mm/s https://drive.google.com/open?id=1ShX0fxi4PutKeM3KguRSdQemK-18Wojt9Q 60mm/s https://drive.google.com/open?id=15Fp3TQ_ciw1H8F8cI1m_5SBTfZnrz6rCrw Does anyone know what's going on is it anything to worry about?

I did not check if there was any leak between the steel coupler and olsson, here is a photo, https://drive.google.com/open?id=1KEjJlS15NGhhUVoiIqbPr3KpaopFI8g-KQ Now I have pulled it apart and know how I can do it again if there is melted filament how do I clean that out?

Well it should have last longer but is around the time it can last. I think maybe the coupler was more tight that it should be and the pressure, since TFM is more flexible than the old PTFE (but OFC old PTFE Couplers only did last 50-200h, so 500h is a good improvement anyhow) if isn't perfectly install it has less life span. Did you use the printed spacer to install that TFM? Was it perfect on the spot? I printed the spacer and made sure it measured 16.8mm but with the new TFM in even the old one could not get it to tighten down to it but its snug and measures (the section the spacer sits in) with my calipers at 17.18mm and a test print came out alot better then it did with the old ftm.

The erosion of the filament, or use. Or, when assembled the pressure was a bit more than needed, crushing the coupler a bit and making its life span shorter. In theory the TFM last 500-2000 print hours. How many your has? 483 hours (going by the status under the maintenance menu) with mostly PLA use with some colorfabb ngen.

Okay looking down the hole it was nolonger round :/ https://drive.google.com/open?id=1pMdKlk1wQMQRMWll5NMuQ4wR-uIUM3PdSQ how would that of happened?

neotko does this look warn out as its not really burned but does have a very small brim. https://drive.google.com/open?id=1iozqqDEbnamuB0tvheDLlhNBstWI8u4d1A https://drive.google.com/open?id=1zTqblpj-Z9vIHv68_xqoQPR27zecvXcUtg

Sorry to bring the post back to life but thinking my TFM might be on its way out still as when it primes before a print it entrusts alot less then it did before and getting really weird issues with prints. How long does a TFM normally last when printing in the 210-230c range I'm now in the 500 hours. Check this post and the next 3-4 post https://ultimaker.com/en/community/35497-is-the-ruby-nozzle-for-the-olsson-block-for-sale?page=3#reply-172875 Thanks that helped alot removed the filament and took the nozzle off and slide filament goes in with almost no resistance but when pulling up there is alot of resistance and shining light down the hole and looking in you can see a little black brim between the TFM and the heater block (if thats what you call it?) so I'll give my ultimaker reseller a call tomorrow and hopefully have them in stock.
