I have a Titan extruder with the pancake motor and bowden tube adapter, it's only a few weeks old, on retractions, the Titan lets out a squeak each time. During regular extrusion, it appears to be fine. I searched the forum button couldn't find any tips, has anyone any suggestions how to silence the extruder during retracts?
Maybe... did you happen to add a washer to the screw going throw the clear case, through the hobbed great and into your stepper motor? if so, remove it.
Yes, I had added the washer, I've now removed it and added a little lithium grease to the bolt, fingers crossed that will solve it. I checked some images and many titans are shown with the washer installed? UPDATE: After removing the washer the squeak is now more of a creak. I also found that you can't really tighten that screw or the extruder doesn't have the power to move the filament, perhaps getting this small pancake motor was a bad idea.
I just rebuilt my Titan to correct an orientation issue, and I added the washer to the bolt that goes through the extruder gear, and now my Titan squeaks, not always, but fairly often. What up? Anyone know? I found that I had the "can't tighten" issue with that bolt and I fixed it by going to a longer bolt that bottoms out before it gets tight on the plastic. The washer I put in to close the gap between the head of the bolt and the plastic case. Now it squeaks. That does not jive, it shouldn't cause that. So, E3D, what causes the annoying squeak? Thanks, DLC
Hello dadly, I faced the same problem in one of my titan. It was squeaking in both way. So i checked and fount that bearing in TITAN COVER (bearing 5/9) was the culprit. So I oiled and put it back. Now no squeaking anymore. You should also check that. Change it or use machine oil. May be it will solve your issue. Good luck and please update if it solves.
I tried soaking the bearing in oil and it didnt fix the problem, but it certainly changed the noise it makes, so I think I need to replace the bearing. Question is does anyone know what the bearing are?
I had the same squeaking problem on my new titan aero. I was wondering what could have been making the faint intermittent squeak noise until it failed yesterday and i noticed the bearing in aluminum front piece had disintegrated. Shavings and black dust everywhere. Apparently im not the first according to the vendor.
I had a problem with a bearing in a Titan some time ago. I ordered replacement bearings from Misumi which worked great. Here is a link: https://de.misumi-ec.com/vona2/detail/221000058378/?HissuCode=F-WBC5-9ZZ1/1K Part number is F-WBC5-9ZZ1/1K
I'm getting a loud squeak and on closer inspection there appears to be rust dust around the bearing. Warranty bearing swap?
I had a similar issue, but when dissassembling the Titan I was shocked to see the interior complete covered in rust from the bearing in the lid. See also the relating topic: https://forum.e3d-online.com/threads/rust-in-titan-lid-bearing.2923/
Awesome; thanks for this. Stupid question: how did you guys get the old, outer ring out of the aluminum heat sink? Mine is cleanly wedged, only part that didn't disintegrate. Thanks! Rob
I am a company... But in certain countries this doesn't matter, in Germany they just sell to comanies, in GB I think you can order as a normal person too for example...
Maybe I should try the UK then. Just wish E3D would start carrying the Hiwin and Misumi stuff directly because not everybody is a company.
Hi guys. At least for my problem (and it looks like for the problem on the video too) was way simpler than anything regarding the bearings. The lever, which rotates from the motor axis and its rotation is constrained by the filament and the spring on both sides, TOUCHES THE MOTOR GEAR continuously. That is what makes the sound everytime the motor rotates either way. I dissasembled the entire extruder multiple times, and found out that that was the 'cause of the screeching sound. My first thought was to wear it down, noarrowing the lever so it creates a gap between the two components, but the design would make the lever slide towards the gear again, increasing the sound (now with a wider contact area). So the solution (partial, and chronic) is to lubricate that contact.
