Introducing Ultimaker Cura v5.0 - A big step forward for desktop 3D printing

[@jasonhurdlow6607]

Thank you for mentioning that it will run side-by-side with version 4. No one, including Ultimaker has said that. I have avoided trying it to avoid risking screwing up my good working setup.

[@robertpelland5649]

Not only did I find this video useful, but I was also very impressed with the intro. Well made, short and to the point, kudos to the author. I will definitely install version 5.

[@marcoaurelioxaviermoreira4631]

Congratulations on a pretty well done presentation of the Ultimaker Cura 5.0, very cool!

[@johnpekkala6941]

A great thing indeed with 3D printers is that the toolpath generator/control software is independent of the machine and not like with say laser/waterjets integrated into the machine firmware/control system and thus propertiary to that particular machine. That means that as long the printer understands the g code commands themselves and have the required mechanical precision it can be updated indefinitely with new features as they are part of the slicer and not the machine firmware. Also in case that the printer firmware might need an upgrade it helps that this firmware (Marlin/Klipper) is also open source.

[@alerey4363]

that's not true at all; utlimaker cura works only with their own list of "supported printers", which is extense but by no means complete, because there are a lot of diy-printers that don't work in cura; in fact you can see these complains in lots of 3d printing forums, ranging from cura not recognizing the printer via usb to printing going nuts (weird noises from motors, sensors not acting to stop head, etc)

[@OddlyIncredible]

@@alerey4363 I have a completely scratch-built 3D printer of my own design, which is about as DIY as it gets, and Cura 4.13 works just fine with it - I duplicated the default material (generic) and machine profiles and customized them to suit, and the resulting G-code prints just fine. In fact, I have a print running right now that I sliced with Cura. Now that having been said, I am ONLY using Cura to slice models and nothing else - I'm uploading G-code to the printer via STFP over SSH, and not through Cura's USB uplink, as my printer has a Raspberry Pi running Klipper in it and functions completely stand-alone.

[@alerey4363]

@@OddlyIncredible if your printer deviates from Ultimaker's line of printer it can be a nightmare to make it work with cura (and there are A LOT of variables to tune in that case, from software in the firmware of the controller, the controller type itself to hardware aspects like type of extruder, reductions, motor type, hotend, etc). I had to resort to Kisslicer which, while not at as "nice" as cura, works perfectly with my diy-reprap printer

[@PantsuMann]

Hyped for lightning infill for my model building!

[@marcusroom3597]

Thanks. Very informative my wife is new to Cura and this was great

[@leektah354]

2:14 So why can it slice the chimney at 10% but not at 15% scale?

[@zapl80]

It's filling the small hole in the chimney and therefore considers it a solid cylinder which is thicker than the minimum line width when small enough. Slightly larger and it sees it as a tube with walls that aren't thick enough to print. You might get this to print on v4 by enabling 'print thin walls' which also prints with a line width below standard. Alternatively, increasing the small gap fill size to print it as a solid cylinder

[@rondlh20]

2:20 At 15% the chimney is missing, but at 10% it is there, quite odd. Cura 5 offers great improvements for me when printing round objects

[@bryandooley5453]

I noticed the same thing. Odd!

[@tHaH4x0r]

This is actually an excellent improvement for the things I do. I generally work with a lot of thin features and flexures. Especially when thin flexures are at an angle slicers can do funny stuff (suddenly have 3 walls at some points of the flexure, some other points 2 walls etc). Generally flexure thickness is limited by the wall thickness, so I hope this new slicing feature will also enable me to print thinner flexures.

[@jakejuracka]

Headed to work right now, can't wait to try this out on our machines when I get there!

[@kevinerickson2595]

I downloaded the updated , but why does your slicer look different 🤔

[@EASTCAMDEN4LIFE]

Mine is different too🤔

[@Vizeroy9]

I like the Lightning infil - saved a lot of material. Sadly, the same file printed with Prusa and 20% infill was done much faster than the file sliced in Cura with Lightning infill selected. Same layer height, speed, temperature, printer

Prusaslicer is just better. Last time I attempted to give Cura another try, I also experienced larger printing times.

[@blarbdude]

I actually fired up prusaslicer for the first time to compare with a large print I was working on, same print time with 20% more material used with the *exact* same settings. I'll stick with cura.

[@notchipotle]

I'm using both version just because the old one can make the seam perfectly in line

[@wickedinvi8466]

Would this new way of slicing and removing the gap fill and allowing more flow for other walls not affect the tolerance? That is if the tool path is the same as before and is not offset which should be the case to accommodate for it.

[@alejandroperez5368]

The whole idea is to maintain wall thickness...that's what common sense says.

[@wickedinvi8466]

@@alejandroperez5368 If you have 2 walls and gapfill making the 2 walls wider to fill the gap without offsetting the tool path will make a hole smaller.

I have attempted to load this Cura 5.0 Beta and for some reason, PCmatic will not allow it to run. I have selected "Run as administrator" and I am still getting the same results.

[@3duniverseOrgWelcomesYou]

Please report that issue to the Ultimaker Cura development team by posting in the GitHub Issues section: github.com/Ultimaker/Cura/issues

[@kevindorris5500]

Kind of the same problem I'm having but with an OpenGL or something error and can't open it at all and have installed and Uninstalled and reinstalled it like 8 times so far and still no go on my laptop.

[@alpage57]

At 6:40 the sliced gear (4.x) shows 37g or 4.71 meters but at 6:51 5.0 uses 31g or 4.02 meters. There's less material in the part. Where was material removed? Infill, shell, top and bottom?

[@tyc0746]

I noticed in all the comparisons, that with the v4 software the infill is spot on 20, whereas v5 infill seems to be set to 18 or 19...would that make that much difference...is it even possible to select single digit increments or does it jump in steps of 5?

[@3duniverseOrgWelcomesYou]

I noticed that too, but I believe that’s just a glitch with the interface. I went into the custom settings to verify that it was set to 20% infill in Cura 5.0. For some reason, the little dot just won’t snap onto the 20% mark on the line the way it should.

[@alpage57]

@@3duniverseOrgWelcomesYou I suggest looking at the infill in the preview and comparing screenshots at the same layer with the two versions.

[@tegaidayt]

This guy! Thank you for a solid instruction!

[@jasonhurdlow6607]

As for M1 "support", based on developer feedback to people mentioning that the binary is still Intel, it sounds like by support they mean "it works", not that they have an ARM binary in their plans. I expect they'll get around to it eventually, but it doesn't appear to be what they meant.

[@BrunodeSouzaLino]

M1 Support == We managed to get it working with Rosetta. The only people caring about M1 Mac support are companies that have a large Mac userbase. The vast majority of 3D printer users are on x86 platforms, mostly Windows. It makes no sense to port and maintain an entire branch of software for such a small number of users.

[@BrianBoniMakes]

That was good, I'm heading over now -thanks!

[@hakunamatata324]

Lightining support alone is worth the update. WoW

[@biggityboggityboo8775]

Is Cura yet able to allow me to use different settings for different layer heights like in Simplify3D? And I'm talking about using/changing all the settings on a layer per layer basis if I want to?

[@3duniverseOrgWelcomesYou]

Yes and no. You can change settings at specific layer heights or for specific regions of a part, but not all settings are available for those changes. You can either use the ChangeAtZ post-processing script to change certain settings at specific Z heights, or you can use the method shown in this video to customize specific regions of a print: kzbin.info/www/bejne/iWqbmYaDbbijqM0

[@biggityboggityboo8775]

@@3duniverseOrgWelcomesYou Okay so you can't. This needs to be adopted into Cura's features. It's the only real, necessary, feature the software requires. If you're part of the development team then let them know this needs implementing ASAP.

[@stolowma]

Sounds interesting but every time I open 5.0 it give an error and the only way to load it is to reset the configuration. Since I really don't want to set up printers and all other profiles every time I think I'll wait for the stable release.

will it reduce the wall thickness when printing angles in otherworld a 45° overhangs so it has a previous layer too print on in order too print overhangs. hope that makes scence...

ths is a majo feat. I'm using Cura 5.0 beta now on my FLSUN super racer and i am having incredible successes over the 4.13 i was using earlier... should that be the case? I'm pleasantly suprised though...

[@3duniverseOrgWelcomesYou]

Hard to say - it would depend on your specific geometry and other factors. But I'm not surprised. I've been seeing improvements in print quality with v5.0 also. I'm working on another video that compares a bunch of different benchmark prints from Cura v4.13.1 vs Cura v5.0. Stay tuned.

First, be sure you download the final release of v5, now that it’s available. No need to use the beta any more. If that doesn’t fix it, you should open a support ticket at support.Ultimaker.com

would have been nice if you included the comparison of lightning infill to the existing tree support option since they are more alike (that wasn't really a fair comparison since technically lighting infill is more just support than actual infill in my eyes)

Does this work with resin printers too? I hate doing a reduction on miniatures and then have wrists, swords, capes... too thin to hold.

No, Cura is designed for use with FDM 3D printers and does not support resin printers.

Hardware retraction its included as option? And volumetric extrusión limit?

[@rjward1775]

Does it change anything if you print at 100%?

[@marcpi8381]

With the increased flow rate (thicker extrusion) what is the affect on dimensional accuracy? For example, does it account for squish and slightly offset the outside wall?

[@3duniverseOrgWelcomesYou]

As far as I can tell, dimensional accuracy has actually improved, especially with thinner walls that are not an exact multiple of the nozzle diameter. But I plan to do more testing and may do another video specifically comparing dimensional accuracy for Cura v4.x vs Cura 5.0.

[@benben0814]

I wonder how you guys achieved the changing flow rate within the G-code paradigm? For me, I always thought that extrusion is synchronized with the speed of the printhead. Any comments?

[@hansdietrich83]

What? No. Extrusion speed and movement speed are seperate gcode commands, so they can be adjusted independently

So this variable line width is NOT a setting or option but rather an integral part of the slicing engine? I ask because I downloaded it and could not find any specific user settable setting.

[@DastardlyDan69]

Minimum wall thickness, I believe it is in the wall tab.

[@3duniverseOrgWelcomesYou]

While there are settings to control certain aspects of this, the basic function of variable line width that was discussed in the video is handled automatically by the slicing engine. If you just take an object and slice it with default settings in Cura v4.13, then slice with the same settings in Cura 5.0, you should see the difference without using any special settings.

[@yazanmanna3344]

Nice added Features

[@Jwmbike14]

If you are 3D printing RC aircraft, stick to 4.13!!! The new 5.0 will work, but it adds a ridiculous amount of random Z seams and more than triples retractions. But I do have 5.0 and 4.13 on the same desktop with flawless results switching between them (profiles don't go from 5.0 to 4.13 though)

Great video and you're getting my upvote + sub; though I found the bokeh effect when you were talking a bit too strong. I like to have my eyes wander around a bit every now and then and refocus on other non-moving objects. A bit of bokeh would be okay, I guess. But the only thing really in focus was the front of your face. Even your ears seemed like they were not really in focus anymore, which irritated me a bit. Though again: I loved your video and this is just something I hope can maybe be useful to you in some way?
