How to print writing better ;)

Eye

hi, i  have a  little problem with  printing  writing   either  Put on top
 or caved in,.. 
 
anny idear how to get the  fine print print better?

michalko99

Hi. What is this language? Or are you spamming? All your last comments are written in Chinglish language and complete off-topic

Eye

well   michalko,
I am Not english native and dyslectic, 
 so no its nit Chinglish, its Eyeneese and not intended as spam,

but  if you  a "Super member"  Think my  questions and comments  are  just spam:
i will stop trying to be helpfull, 

Thank you for your  input regarding how to get  written text printed better readable

I find with a little creative thinking I can usually understand, or I ask for clarification.    I am assuming you are trying to 3D print with text embossed into the object? Can you please provide a photo Eye.

michalko99

Sorry about that. I did not knew that. I am also moderator on 3D Geeks app and I see a lot of stolen accounts where speaking became garbled and I have to report these accounts, because they start spamming a lot in a few hours/days.

My native language is Slovakian by the way 

Which software are you using for drawing?

Eye

Hi samuel,     yes embossed or  cut in either way,  
i seen better but that came from a different Printer with the same nozzelsize...

This is  0.4



michalko if my typing ever becomes flawless its time to check my identity,
and your English seems ok for me, but as saied i fight  with ma motherthoung on a good day
 

I use  rhino 5 for my 3d experiments But my Problems are also with stuff from  thingyverse like that nozelbox In the picture
Vcut in  stuff is hard to read too,
it seems   its a bit better on the side

hi. For me, it looks like a very high speed and overextrusion. For my personal settings, I am using experimental settings in Cura all the time. Also retractions seems to be set wrong and insufficient cooling. I had also problems with marmor PLA filament.

Stock cooling fan duct is completely insufficient if you are using it

Eye

Aaaah I can post again!!!!

i will try out to play with those Settings, i try at the moment with PETG

2 Added Questions:

A) Could smael nozzels Help with it?

does that change behhaviour for outerlines,
i found that if i print something that shoudl fit snugly like a wago clamp holder that thing whont fit,
like The Outer lines are to fat /not prcise enough ?

Best regards

michalko99

what size of nozzle are you using?If bigger than 0.4, this would answer why letters are fusing together..

Eye

So far i only used 0.4

Samuel Pinches

@Eye how are you drawing the text?

michalko99

OK. So might be problem with high temperature and high speed. Small feature speed is exactly for these small sections.

try to print calibration cube. Its worth nothing of filament, but will say much of printer settings. Can you also make screenshots of your Cura settings?

sam: using the letering Of rhino,
Michalkos: printig a 20³ calibraton cube at themoment in petg

Below an exported Condensed verion of the cura file, i take thats whats not standasrt?

It is very hard to see the surface finish with a translucent filament
Could you also please share the STL or a screenshot of the lettering region in the STL? To compare the file with the printing result. Thanks.

Eye

That 2 cm block, does quite well;) but i can try with something i am working on, and is far more finiky
https://www.thingiverse.com/thing:1278865 ( stl of the cali cube)

i can giove you the STL of that..
and will try to print it for a fotin in non tranparent PLA later

Eye

michalko99

Hi. Can you refocus on cube? You photo shooted on glass, so your camera took sharp picture of 3 LCD monitors and ceiling, but cube is blurry

Eye

Well that Cube is not the Target anihow, i did some experimenting, and the lettering i whnat seems to be belo the things posible i eaven tried out 0.2 nozzels;) i will put some pic here o The latest with something zi the size compareisn

seems its quite hardto print letters below ziize 3

Eye

thats kind of what i tried...

tzhe square ones are Diffrent tries , with diferent fonts and Different nozels,
the hex one is a later redesign

Eye

michalko99

Ah I see now that you have problem... Font is too small to keep up with nozzle size. For 0.4mm nozzle thinnest readable for me is around 7mm. Compared with USB connector, font is really small, so 0.2mm nozzle is good choice. But they are easy to clog. Also in Cura, cooling section, adjust minimum layer time. For PLA I usually use around 15 seconds minimum. This will slow down printing to let previous layer cool down and avoid warping

Oh. I forgot.. Are you using stock filament cooling duct? I found it insufficient from beginning. I am using customized from Thingiverse. On my FlsunQ5 was stock duct same-only blowing from one side. I had to replace it as first thing

Eye

i did experiment quite some with the fonts, with some kind of surprising results,..
Thick /bolder fonts help a bit, also there one called geert I think which seems to be designed with 3d printing in mind

smallest Printable for .4 nozel was about 2.8 fontsize and the difference between an 0.4 and a 0.2 nozzle was not that great (had hoped for more) ,)

the squares are 12 mm, the 3 in the hex one is iirc 4 the 02 3 and the S a2

Samuel did advice to go for 0.5 mm hight so that is whats used

Also The Silver spool is getting to its end and the filament is quite ,. warped
and the whole thing got ( with 0.4) suck so hard i had to cut the tube again... might have to buy a new one again but thats the fun with all 3d printing

I reduced leyier tim to i think 8, ages ago To reduce stringing

regarding The duct...

WELLLLL
some i found on thingyverse did not quite fit so i remixed one a bit
so i now use https://www.thingiverse.com/thing:4821192

with 2 50 mm Blowers and, No added duct, as that thing seem to be TO good at cooling
i have the Print fan down to 50% as it leads to problems with the heatbed if i go for PETG

With that i have verry view problems regarding sitining except if i use PETG and eaven there its just a Bit

michalko99

for PETG it is recommended to use cooling fan at around 30%. There is problem with layer adhesion and infill breaking. With no duct you are cooling nozzle too much which is unwanted. Cooling duct shall be pointed on nozzle tip and below

Eye

do you have a duct taht you like,
u tried severl round,and C shaped The problem was that the >Bed< runs in a heaterror not the nozzel,
the 50x20 fan is in my standard settings atm is start 0, and gets up to eaven 50 % t some layers without the duct,..

michalko99

Yes. I am using only this one for a few years. https://www.thingiverse.com/thing:2788702

I printed it from white ABS and so far no deformation. It is used together with this mounting kit.
https://www.thingiverse.com/thing:2977464

No complaints from my side and cooling is perfect

Eye

He i tried those, But the smaler fan was quite loude That why i went to the other one
and the duct i did Try some times ago,.. But in pla. maybe not the best material

michalko99

You are right, that 5015 fans are louder. I have it on place where noise is not a problem. Mostly I print ABS and PET-G on A5 so all my printed upgrades are made from ABS and annealed then. When I print parts whose require 30 hours to print PLA would not last for sure from radiated heat

Eye

my JGAURORA!!! A5 stands in my living room,...
I am Thinking about reducing its speed of those with something like a resistor...

Also some friend of a friend did print some of my STLs through one of those smlly light pinters and the result Acryl well

as thought if i can print ot Okish with mine,.. It looks splendid with those.... ,(

michalko99

Do you have TMC2208 stepper drivers upgrade? Without them, printer is screaming like Ender3

Eye

Realy looks good or?

and no, i have replaced my stepper some time ago But with original ones, and have it singing

i am a bit... worried about messing up the settings
