Random 3D printing chatter

Ah, you'll want the model
and then the containers themselves (as the model page shows) are available in two versions. The one you want has three grooves for a handle rather than one much deeper handle that restricts the width of the spool.
If you search for "Skroam 4PCS Cereal Containers Storage 4L" you'll find the correct one... although there are probably identical ones with a supposedly different brand.

As it happens my Centauri Carbon threw up a serious error message overnight relating to a fan. I tested them all and they all seem to be working but the print is "warped" is the best description I can come up with on one edge so maybe something was too hot. Anyway, it looks like I am going to replace the lot as a precaution.

So, they sent me the wrong mainboard fan but as it turns out isolating the stock fan from its mount decreases noise significantly.
The case exhaust fan the 8020 one is quieter with the new lower rpm one but what made the biggest difference was getting rid of the carbon filter infront of it. The filter us useless junk anyway but it massively restricted airflow and created significant noise from turbulance.
 
Is any old lithium grease ok to use for the screws? I can't find the little sachet they sent me and it's just said that the time has come to do the screws and rods.

Also the wiki seems to suggest standard WD40 is OK to use to lubricate the steel rods themselves which seems random. What about bicycle dry lube or something like that?
 
I would think anything which doesn’t break down rubber or plastic is fine.

Silicone based grease and lubricant is probably preferred.

Edit: I wouldn’t use WD40 for that reason. WD do a silicone product which is fit for purpose, I’d assume it means that.

No it's weird on the wiki they just say the multi use wd40. Ok not the penetrant but also not the lube nor the silicone product.

I'd personally have put my silicone based coffee machine/brewing lube on everything as that is generally safe on everything but the wiki has stopped me. See the instructions here:

That is odd when they say silicone grease is fine elsewhere.

Perhaps they are concerned there is a lot of different sprays in the specialised range and people will buy the wrong one.
 
TL;DR New H2S broke after 8 days and Bambu Lab, with me doing the donkey work, got it working again.


My Bambu Lab H2S was delivered 4 weeks ago and for the first 56 hours of printing I was amazed how good, and quiet, it was. 8 days after I received it, during a print it started making one hell of a noise so I cancelled the print. I discovered that the X/Y motion was very off and not operating properly at all. If I moved it towards me on the Y axis it would also move in the X axis.

I created a ticket with BL and sent them some videos. They came back a few days later saying they were certain, from my videos, one of the X/Y motors had failed.

They offered me a few options....

1. They'd send me 2 X/Y motors for me to swap out as well as a random roll of filament.
2. I could get a replacement by returning my H2S first and when they had checked it out they'd send me a new one.
3. I could buy a new one and when that was delivered they'd take the broken one back and then refund me.

I decided to go the repair route as that would be the quickest option, plus I get a free roll of filament. I received the motors and filament 3 days later with he only down side being the filament they sent me was a PLA Basic Jade White Refill Pack. White is not a colour I use much, black, grey or red would have been better, but I have several empty BL spools so no big deal.

I finally got round to changing the motor(s) this morning and I was hoping it would be the far easier of the two being the issue and, thank <insert swear word here>, it was so I didn't need to take lots more off the printer to gain access to the other motor. The broken motor, when I got it out, felt terrible and had so obviously failed.

I will admit I was really ****** off when it happened but I also understand no manufacturing process is perfect and, for me, it's how problems are dealt with by a company that really shows if they're any good or not. Fortunately, in this case at least, BL were good at aftersales.
