Random 3D printing chatter

If you're doing gifts, you'll need these: https://www.printables.com/model/178035-cute-mini-octopus they go down really well....possibly too well.
and if you have more time, these: https://www.printables.com/model/413203-articulated-night-spirit-dragon they look really good in the tri-colour PLA you can get.
A lot of the 2D low-poly wall art goes down well too. White tack or other sticky to hang. Quite a variety on Thingiverse but this was a convenient link: https://www.printables.com/model/849511-hummingbird-low-poly-wall-art

The Poly Art looks great! Will defo try some of those. The Spirit Dragon was the first thing I printed overnight, it's very cool!
 
@vail3r Ah Skadis pegboard....now there's something you won't find a shortage of premade models for! There's probably a remix of that Star Destroyer with Skadis mounts!
Filament does that; only runs out when it's least convenient. Even if you have a follow-on spool in an AMS changer, should you feel too smug about it, the end of the filament won't let go of the empty spool and it'll jam instead of switching to the next spool. *Facepalm*

Yes I’ve already printed some small trays and a battery holder for it and I’ve got a list of other handy bits to print!
 
Had a weird experience with nozzles.

I've been using a hardened nozzle on my delta (FLSUN V400) for 1000s of hours, and I really like it... but... I wanted to try a higher flowing nozzle. One that didn't cause the extruder to slip (click) during filament loading (last 25% as it's a long load and the nozzle can't keep up).

So, I bought some cheap nozzles from Aliexpress, that have a central brass insert that splits the filament for faster heating. Now, the weird part is, even though it has zero issues with loading, it also seems to be LESS efficient in heat transfer. My PETG is matte at 250C and didn't bond as well, when with the hardened nozzle from Microswiss (plated A2 I think), it was nice and shiny. So this leaves me a little confused.

So... I start a taller print, and do 260/270/280/290C manual changes to temp, and whilst 260C made it shiny, even upto 290C it made basically zero difference in quality and nothing really visually. I then created some strength test parts to snap off, and again... made zero difference that I could tell to strength.

Little perplexed. It should really have been being burnt/a mess at the higher temps.

So for now, I've resliced my stuff at 260C, but created 250 to 280 profiles for it lol, just in case.
 
I'm sure I've read that some nozzles have to have the temp raised because they conduct heat more/less. Could be that or it could be a less efficient design to get round Bondtech's patent or awkward machining requirements.
As the temp is raised "too" high, could the slicer be increasing the flow rate to compensate?

Yup, not all nozzles are the same. I was just surprised because a hardened nozzle normally needs more heat (hence my standard 250C (i.e. +10C over what I would normally print PETG), and this is a high flow, and actually needs more heat. Perhaps the rest of the design isn't as good at transferring heat as the core of it.

On the plus side, I also did a whole load of maintenance to my V400 whilst I was in there. Regreased all the motion rails and ball joints on the arms. It has resolved the Z wobble I had just started to see.
 
I'm printing TPU for the first time, the last parts for a filament respooler, and hopefully it'll go smoothly (looks OK so far). I'm using my X1C but the other day I was thinking, I wish I had an A1 Mini for this sort of thing. When it's back in stock I think I'll order one sans AMS as I don't need an AMS with one of them.
 
Little update from my previous questions regarding what printer to get, I managed to nab a Neptune 4 pro locally had it dropped off to my house and it was all checked before the guy left as he insisted he wanted to make sure it was all working fine before he left (ran a 20minute or so print).

I’ve printed off a few things myself mainly using files I found online but I started to have a dabble in fusion 360 to make my own custom prints.

Unfortunately one of my kids went on my computer spilt coke inside of it (mesh on top and stupidly put a glass of coke on there) and didn’t tell me until I went to boot up the pc the following day.

It looks like the pc is fried only things left working are psu and ram, gpu motherboard and cpu are dead.

I’m not in a position to replace all the parts due to me having to quit work recently due to health issues. Is there any recommendations for a sub £200 laptop (2nd hand is fine) that would run fusion? Prints I would be making are not large in size mainly clips/brackets and random low profile parts.

Was starting to run out of my first rolls of white and black from eSun. Decided o take a punt on Jayo from AliExpress, 5 rolls of PLA+ mixed colours for £40inc. I've read they are the budget brand of Sunlu so thought why not.

On another note, has anyone found a free topology optimisation software similar to Fusion's? I stumbled across a topology optimised shelf bracket and the whole idea is interesting to me plus it generates some unique designs. thought of designing a few household brackets but realised it's not free.

I've sent you a private message (conversation).
 
I use the cheap grey JAYO off amazon. Most of my sales use it.

Never really had an issue.

I get 10kg at a time. I think I've had 200+kg from them

Got a couple of rolls of PETG, and a couple of PLA (not sure why as I really only print PETG these days) from the Sunlu store on ebay. All 4 came on new reusable spools which is a first, shame they don't seem to sell refills in the UK yet!
 
Just got my 0.4mm hardened nozzle for the A1 Mini. Maybe next month the A1 Mini might turn up to put it in! :rolleyes:
Stock is really very random - if there's a few different things you want, there's no way you can get all of them on one order. I tried but I think it's going to be 3 orders.
 
What does the hardened nozzle offer? I was thinking of getting a 0.2mm and a 0.4mm hardened as it seems required for marble/cf or textured filaments. Anything other than that?
