Heaven help me - I've just bought a delta kit :-)

[curious aardvark]

haven't tried that yet. get this next nozzle printed and I'll have a play,

[curious aardvark]

lol I have an actual official version of s3d. Reinstalled fairly recently
This is the only model that's crashed, also the most complex I've ever tried to slice, thinking maybe I need more memory in the computer.
Should be some on the shelf.

Yeah spends a long time 'initializing preview data' and then drops out. So probably memory related. I'll drop some more in and see if that makes a difference.
The fact that 'initialising' is incorrectly spelt with a 'z' could also be the problem ;-)

Doubled ram to 4gb - doesn't make any difference.

I will try and slice it with cura.

That works, must be my s3d install.

Final fan duct setup:

Duct without nozzle:

Top down view of carriage and duct.

16x9x10 nozzle.

16x9x10-nozzle_247x480.jpg

As long as you use a 10mm or less height and length, the nozzle stays clear of the printbed.
You could have more height and less length. But 10x10 is pretty optimal.

I'll upload files to thingiverse after lunch.
Including just the clip so people can add their own nozzles.
Might seperate the nozzle modules and see if I can make it a thingiverse parametric script.

This duct is designed to fit number40's larger carriage. Not going to post the file for the smaller carriage - as people should be using the larger one anyway :-)

No extra screws, bolts needed. Fan push fits and is a good tight fit. Mounts using existing carriage bolts and nozzles just clip in and out, again a good tight fit, but easy to change.
I added a wire extension, wrapped round the main cable conduit and plugged into the fan socket on the motherboard.
So I've got complete control of the fan - which is pretty neat :-)

All in all, pretty please with it.

Without the fan overall weight is about 7gms. It's all 1mm walls except the bolt plat which is 2mm for better strength and a really solid fit.

[curious aardvark]

0.2mm and 150mms :-)
Definitely not switching off retraction.
moot point - for some reason it won't slice on this machine.
I'll wait for the next s3d update and see if that fixes it.
No big deal :-)

What autocorrect spelling ?
The red underlines ?
As many american words are incorrectly spelt anyway - I tend to ignore them :-)

[curious aardvark]

pictures should be showing up now

[curious aardvark]

weird they show up for me.
Anyway added to thingiverse now: https://www.thingiverse.com/thing:2386628
I'll go upload them again on here.

Absolutely does not need to blow out a candle.
Cooling on a 3d printer doesn't need to be particularly powerful. Just needs to be able to cool the filament a few degrees faster than it would normally.
So no, won't blow out candles, won't blow down houses of straw or sticks.
But it will cool down filament enough to significantly improve quality of prints. Which is actually, what it's for :-)

Plus the filament on a delta cools down faster than on most other machines - the stuff I've been able to print without a fan has proved that.
The extra cooling this adds does the job :-)

ah - don't think I've got any 4gb dimms in stock. never usually need more than 2gb on my workshop machines.
Given that nothing else I've sliced has ever given me issues, it's more like to be a windows/memory issue - I only build machines with ssds, so virtual memory should be pretty quick.
That said - cura sliced it without any issues.

Tell you what though. Currently printing my first proper thing with the fan. A radiator pressure valvey thing for a plumber mate of mine. Doing in pet-g - the ones i did without the fan were pretty rough. The one it's printing at the moment looks bloody amazing !
Mind you i took amaprof's advice as well and knocked 10c off the printing temp.

I'll do one without an as well just to compare.
But it's looking really really clean and sharp.
I'll take a pic

radiatorwidgetbeing printed_454x480.jpg

printing at 0.2mm layer. I mean come on how smooth is that ?
The layer alignment on that column is bloody amazing.
The larger carriage is probably helping as well.
Cheers mate :-)

This machine rocks !

***

The surface finish on this thing is bloody phenomenal !
I reckon Alexa is finally 100% finished :-)
It's sun-lu pet-g at 230c. Which is the lowest end it says to use on the label.
Accordig to amaprofessional, it actually bonds better at lower temps.
We'll see. This thing is screwed directly into a radiator valve, so is subjected to some serious sideways twist and torque.
The 245c ones were fine. Interesting to see how this one at 230 compares. Plus I've extended the bit that screws in.

Right started the one without fan.
(sticks finger on fan) yep definitely off.
Be interesting this.

So does the fan make a difference ?

Oh hell yeah !
Guess which print is which. Only difference is one was printed with fan on and one with it off. All other settings were unchanged.

The surface feel is even rougher on the non-fan one than it looks.

The one with fan isn't quite as smooth as injection moulded - but damn it's close :-)
With some light sanding - you'd be pushed to tell the difference.

Think that proves my point on cooling fans quite nicely ;-)

[curious aardvark]

Printed one at 0.3mm and 100mm/s - looks almost as good :-)
