My 4.11 profile download was missing a couple of the smooth profiles. It’s been corrected. Re-download to get them all.
Where can I find the profile?
Link in description.
@@FilamentFriday Thanks
Hi ,
Can you please make video of 3d print toys comparison of ender 3 max and ender 3 V2
What kind of toys?
I find they print about equal for most prints.
Chuck, mono tonic is mostly relevant for shiny filaments (like metallic/silk). The direction of print (left to right and right to left) effects how light shines back from the surface, so the the surface is shiny you can really tell the difference. Try it out.
I avoided watching this because I was working on a video on the monotonic settings and wanted to come to my own conclusion. Finished it a few days ago so finally got a chance to watch this. I had really good results with monotonic ironing and depending on the size of the part/geometry was able to see a difference with non ironing monotonic layers. That being said there is no denying the changes you made had a much higher impact on top surface smoothness without need to enable ironing. A few of these settings I have actually not played around with before. Thank you very much for the information and tips 😬👍 there is a never ending amount of things to know 😂
I look forward to seeing your results. It’s not about ironing, it’s how to get the best top surface and Monotonic alone has not done a lot in my experience and also looking at other channels results.
This tutorial helped me figure out a problem I've been trying to troubleshoot ever since I got my printer.
My issue looked like either it was over extruding, or dragging the nozzle through the filament, leaving scars on my layers and jist overall tearing it up. This whole time it was that skin setting. Because it was overlapping filament it was adding more than was needed, dragged it all over the place, and then compounded with each layer.
So all in all, thank you. This video completely saved the hobby for me
The monotonic printing appears to print in one direction. As there is difference in line geometry if it is laid down next to another line, the light will reflect differently depending. On the default print that difference will be visible where it changed directions, demonstrating the sheen differences highlighted in the documentation. Monotonic printing will address that.
To relate it to something, it is similar to how you carpet looks different on a push vs. pull. The 3D print just happens to affect the sides of the line.
The gap closing by setting the wall inset was a great tip Chuck!!! Tried it as soon as I saw the video. Makes PETG prints solid. Especially if there are any trough holes. Nice one!!!!
CHEP Profiles are by far the best you can find. They bring you to the next level of 3D Printing and having them explained is really useful. Really happy that you are still updating them Chep. Thanks a lot
Thanks
Great instructions how you create visual smooth prints. Nice tricks! But I think there is a misconception how monotonic infill works and what the effect is on a print.
Monotonic basically assures that a skin area is always printed in the same direction. Since some of the material properties are depended on the printing direction. Polymer strains are orientated in relation to this direction, the profile of the deposited bead shows line related to the print direction as well and this surface corelate to the light reflection. I assume that is because the shear of the skin of the deposited polymer is different in the wake of moving nozzle flat area. Which creates a surface texture in the skin orientated based on the direction. Disregarding other material properties and just focusing on visual properties.
What we basically do is devide the region of skin in cells or nodes, when these nodes in the graph split up we know we have a new unique region. This normally happens around holes or influx points along a curve. Normally we don't care in which direction the infill pattern of such a region is printed so we optimize these as your normal traveling salesman problem. But now we constrain it to print direction, perpendicular to the skin lines.
Now this will add some extra travel and therefore time. But generally speaking travel time is a few percent over your complete print. So we're okay with that.
A misconception is that the surface will be less rough. It only has an impact on the visual properties and appears smoother.
Maybe we should have stated it a bit different in our change log and what's new pages.
Btw I would still like to invite you to share your profiles by shipping them directly with Cura.
Stating it different in the change log would help as it states it makes top surfaces smoother. I prefer to keep my profiles separate so I can update them at any point. Thanks.
I've been following and subsribed to you for literally one week and greatly improved my prints, in which I was struggling a lot for a month. You share the best videos with the clearest explanations. I wouldn't have guessed I would learn this much in one week. And now you released your profiles?!?! Unbelievable! I wish I had an income to support your patreon, but I will some day :)
That's crazy generous of you to not only share your vast experience of Cura, but to also give the profile away for free! Thank you!
Hi Chuck, Thanks for your generosity in sharing the outcomes of all your hard work. The profiles are invaluable.
Okay that gap closing is really nice thank
Man, chep is dropping knowledge on this one. I am still learning all the tricks in cura to get the best possible prints. Thanks again!
You are without doubt the problem solving King. Thanks Chuck...maybe Crura should employ you as their chief editor of Cura!
the fact that you added these smoothtop profiles proves you are still a legend
Some of those are not applicable to every situation, for example "outer wall inset" destroys small 3d text, but the suggestion to remove the skin-wall was great, that along with a small increase to "compensate inner wall overlap" finally fixed holes I had for years!
Decreasing flow by 5% to 95% worked great for my prints!
That’s built into my profiles
Chep, you are nothing short of a gentleman. Thank you so much for all your help!
You deserve so much more then 208k subscribers for the amount of work you do and knowledge you give us
Thankyou
Thanks for your work and your free Cura profiles. I use them all the time am really happy with my printing results 😊
Chuck thanks for the profiles. I'd be lost without them and really appreciate you making them for us!!!
So many settings to think about. I have a lot to learn. Am ordering my first printer next week.
This chanel eeally helps me understand stuff about 3d printing and it helps me get tips and tricks for my settings in Cura. Thanks man!
It's crazy how much you have to change for every print. If I started 3d printing someone said me you only need to get one good profile and you just have to press print in future. But thats absolutely not true. Sometimes you need more Extra infill walls because you have a low density infill pattern, sometimes you need gradual infill steps, sometimes you need more walls to reduce small infill lines. Or you can print way faster if you're printing big parts, you can reduce retraction if you're always within your parts to safe time...... its so complicated, but its so fun :D
I need to get back to printing, had lots of time during pandemic but my computer crapped out and had problems with my new machine. Love your content.
So useful! For some reason Cura wasn't updating in my system for months but today I discovered there are appimages on the site so I can have 4.11 too. And some plugins that never appeared in earlier versions for me suddenly appeared. Happy 3d printing day for me :)
You are the King of Cura profiles! My prints are so smooth now!
In addition to being smoother print the corners look sharper with your new profile. Thanks for the tips.
I had downloaded newest ver yesterday Thank you for this
Thank you for all of the great information you provide. Have seen so many of your videos just by searching for topics and just started browsing all of your content to see what I missed. This has been a game changer. Many thanks.
Excelet video. Never knew that adding a 0 before the 90 would change the line direction. Quality of my print will be amazing now. Thank you
I like what your doing homie. No fluff, just the good stuff!
Interesting, lots of work to get that smooth top. Amazed how cura messed up monotonic so bad. In Prusaslicer it's one button, beautiful results.
recently i wasn't satisfied with ironing results, and here it is ! Thanks
Thanks again for all your insight and posts, always grateful I joined the Club, when we got our 1st printer, so much valuable information and saved us from many mistakes and much frustration.
Thanks a lot, it works fine, no ironing, no monotonic mode, just some adjustments in the good places and the result is there!
My dear Chap, you did it !
This time you mixed a combination of inset(half of nozzle diam.) , extra skin (=0) and walls (-1) and your settings are really the best !
This is the result of R&D.
Good !
But please note also other 2 secondary effects of your settings:
1. your settings have REDUCED DRASTICALLY BULGING of corners in the cube, and this is because bulging is the results (partially) of excessive materials deposited during walls printing. But because of ur removing the unnecessary walls, you also reduced the bulging as well.
2. FASTER PRINT:
The printing time have reduced of about 10 %
(I have reproduced your suggestuion on a 200% scaled cube and I the time went from 1h 16 min. to 1h 10 min. (about 8 percentage less)
Nice job!
Thanx Chuck. I wish I knew this a few days earlier. Just finished a major order of many small flat pieces where the top and bottom surfaces gave me headaches for days. This would solve everything....
Hey I just wanted to say that you've really helped me to figure out issues since I got into 3d printing. Much appreciation
Exelent! Ty your profile ate rhe Best iam using from years anda work perfect
Thank you for sharing your profiles, I gave them a try last night and not only have the prints come out smooth your settings have cut my times down significantly from what i was printing before. MUCHAS GRACIAS my friend
Glad to help
Thanks man! I’d be lost without you.
Just popping by to say hey! Still cranking out the quality content Chep, I love it :-)
Thank you very much Chuck! You make everything so much easier for the community! Those settings are awesome, I'll be using them for sure.
Another thing i wanted to say is that i think monotonic setting is for models that have a big surface and extrusions on top (or even holes), to make that surface smoother, because cura likes to leave the part where you have a hole or an extrusion for later, and that seems to make the surface finish incosistent. I think that couldn't be seen in a chep cube since the z on top is inside the model. Maybe I'll try to print some test prints and see if that is the case.
Cura despartly needs a popup thumbnail to illustrate all these very fine grain settings.
Thankfully we've at least got this awesome channel, thanks Chep!
*desperately :/
With 4.11 a new plugin showed for me in the market that’s tries to do this. When you hover over a setting it has larger detail description and images. I’m on the road so can’t check for its name.
Settings Guide. It’s been in Cura for a while.
Happy to see a TPU profile - I bought a KG spool of it recently and the standard profile hasn't been so great with it. And I appreciate the smooth top profiles as well, look forward to trying them where it matters.
Thanks Chuck. That was quick ontop of the Cura release.Much appreciated
One of the better videos to date! Thanks a ton, Chuck!
Thanks Chuck :) your profiles improved my printing 1000%
This was awesome, you made it clear and easy to understand what's going on. Thank you!
Great tips for top finish Chuck. I've never tried playing with the top lines directions let alone the width. And that Outer wall inset, which I kinda knew existed but forgot about it, will help a lot on 2 wall prints when the slicer keeps leaving a gap between the walls. Thanks.
This gives me some great ideas. It looks like your initial print showed under extrusion on the top surface. When you moved to 0.28 this worked to fix the under extrusion.
Monotonic is essentially like a perfectly striped lawn. It makes sure that the filament is laid down in a consistent back-forth-back-forth pattern. There are no adjacent strands of filament running in the same direction (which can otherwise happen on complex shapes). I don't think it actually makes the surface smoother. But it makes it look more consistent when it catches the light.
Thats right. The explanation that chep gave about monotonic ordering is not correct.
The effect is mostly noticeable under extremer angles with glossy material
Guess I gotta download your profiles again. Thanks Chep! 😁
Changing top/bottom line width made waves on the top side of my print
.
Hey Chuck, I think the monotonic option attempts to print in one direction only, in order to avoid having a slightly different finish on the surface. I think you should check on more complex (but still flat surface) and maybe try to focus on the reflection of the finish rather than tiny gaps, I think we should find greater difference there.
I think the logic behind it is that if you print using the same direction, the part which is touching the line of plastic which just got printed, it will touch the same side of the tip, and the pattern should be same.
If, on the other end, you print in both directions, the tip touches the part just printed on the other side of the tip also.
If the sides of your tip are not perfectly symmetrical, (maybe not microscopically speaking but close that point where it might be weared-off differently or slightly dented on one side, not the other) I guess we could see the finish being different
I remember the first time I used ironing, I had a lot of text on the top, and yes the surface was very smoothed, but because the printer had to stop resume the top in different zones to avoid the holes of the text, we could clearly see different reflections in the material, killing the evenness of the finish. Maybe there is also something involving a change in temperature, because when the printer comes back to a zone printed earlier, it might be cooler and affect the finish of the plastic being put juste aside of it.
At that point, I imagined there could be an option in Cura where I would say "steady one shot top surface without any traveling", that would just print using a steady motion all over the print, in one shot, a big zigzag in a rectangle path over the last layer, not skipping and travelling fast over the holes but just keeping the same speed as when printing, but letting the extruder do its job and stop the flow, maybe even without any walls for this last layer...
You see it mostly in larger surfaces. Prusaslicer and Superslicer have supported this for a long time, good to see it in Cura.
@@pizzablender yes a big shout out to Prusa Slicer for coming up with that printing strategy.
We have added the strategy to Cura due to frequent request from our community members.
Thanks Chuck for all your hard work. It is very much appreciated.
Pretty interesting indeed, Chuck! 😊
Thanks a lot!
Stay safe there with your family! 🖖😊
Thank you very much for the profiles! Theyve been workibg great for me so far, only had to fix the retraction since I changed to direct drive!
always gives new to learn! you are like Joshua Bardwell in 3d printing. Thanks!
Hey chep, one of the cura developers here. I think you misunderstood the feature. It doesnt make it smoother, it changes the visual properties. With the material you used, it wont change much. The biggest difference is with glossy / shiny surfaces.
The why does Cura advertise it as making top surfaces smoother?
Check the What’s New feature description. I briefly show it at 0:43.
If your right, then it’s false advertising of the feature. So instead I showed some settings that actually give you a smooth top surface.
@@FilamentFriday Ah, I get the confusion now; It makes it look smoother. But it's only a visual change. If you were to measure the surface, it's not actually more smooth.
I really thought the developers had finally addressed Cura's annoying habit to jump around when printing an even surface, creating an unnecessary patchwork effect.
@@FilamentFriday I guess it’s just time for me to unsubscribe. You don’t even try to listen or understand.
@@MetalheadAndNerd We did. That is what the monotonic is for. If you combine it with the combing strategy "not in skin" you get a really smooth looking result.
Thank's Chep for this settings. Prints look awesome!
Another successful meeting, thank you for all these explanations, greetings from France
Looking forward to seeing you at the next meeting :)
your legend chuck!!
Thank you CHEP for the profiles it really helps.
Awesome tip thank you! I also couldn’t see any difference with monotonic but I will definitely be trying that wall trick. Thanks again.
Really nice profiles Chep. Thank you so much!
WOW...I learned A LOT in 5 minutes! Thank you!
Wow! That was EXCELLENT! Can’t wait to try it! Thanks!
I've been looking for something like this. I started calibrating my flow and then I started having gaps between walls and infill. I also didn't even know about some of these settings. Thank you!
Nice one, diving a bit deeper in to the settings.
thank you so much worked better than I expected
Thank you for this. I had problems with ironing.
Wow, beautiful top layer. I would have guessed it was ironed.
Thank you Chep, you are a wonderful and helpful person!
You have a great show.... been watching but first time commenting..... great info and I tell a lot of newbies to your channel..... best info for 3d printing as far as I'm concerned..., but that's just one man's opinion 😁
Thanks
That top/bottom line width made my day! :) Thanks!
Wow. That is super handy, I’ll definitely check this out!
Just found this page, really high quality content. Immediately subscribed and I will be checking out much more of your content soon. Might have some questions for you in the future :)
Another very helpful vid, thanks Chuck!
Fantastic! Great content as always! 👍
As always a massive help. Thanks Chep
Thank you so much Chuck. You're the best.
Changing the top layer line width to 0.28 basically does the same thing as ironing, since the flat part of the nozzle is smoothing over the other lines in an overlapping pattern.
I think it's trying to laying the filament in the same direction while previously the last part of the infill could be laid down by going around and close the infill going in the opposite direction the earlier part was done if that makes sense. That would cause a visible edge. It's like dominos falling in opposing directions giving a pattern difference. But your printers compliance/backlash is so bad that it hides the advantage (spacing if the infill looks like in pairs while it should be evenly spaced). The 90 degrees infill on the second attempt is much better as it hides the backlash.
I enjoy your video's and your
explanations of what each setting does and how it works. I have seen some other video's where Ironing works beautifully, but at much higher speed and higher flow. I'd love to see a video from you where you dive into Ironing. Your settings here work great. But there is those parts where a perfectly smooth top is needed.
If you need perfectly smooth top, print it upside down on glass.
@@FilamentFriday My printer has a textured PEI bed. But I’ve actually achieved perfectly smooth tops with Ironing. At much higher flow and much higher speed than the default cura settings.
Nice. Where do you share your settings?
Chep, as always, you are the best
Really hoping you come out with a .6 and .8mm nozzle profile.
Very good, I thank you very much CHEP, I can make better things now. I only need to learn how to sale it. Thank you
Thanks heaps Chuck very helpful tips there
this helped me with my new glass bed thxxxxxxxx
Thank you love your profiles
With PLA I don't bother with the monotonic ironing order, but with shiny PETG it makes a huge difference on bigger parts
Beautiful printing!
I do like how these open source slicers borrow from each other. Cura finally gets monotonic, prusa finally gets fuzzy skin. Nobody gets sued.
SUPER GENIAL, muchas gracias maestro. Saludos desde Argentina
Thanxs A lot for all your help, i love your videos, Hello fron mexico.
That's really cool, thanks!
Thanks for show me how to use it.
Thanks for the great video, I'm learning a lot.
