Aight!
This is a sort of news video I guess, let me know if you think these kind of things
are useful.
Back story - cura 5.0 or so, I think it was 5.0, broke vase mode.
I'll explain what I mean, this is cura 5.1 and I've loaded in a solid
object - if I slice it in normal mode...and go look at the first layer, looks pretty normal.
The important bit - foreshadowing - is the bottom infill type, or "bottom pattern initial
layer" and "top/ bottom pattern" and it's set to "lines" and it is lines, all good.
But if I select vase mode, spiralise as it's known in cura because, you know, cucumbers,
once I do that and slice it you notice the base is actually not lines any more.
It's this circular pattern which is known as concentric, and I hate it.
You can see this is a bug, actually there were a couple of bugs raised about this.
The reason in my view it broke vase mode was because if I print out this vase on the flsun
v400, you can indeed see it's printing concentric rings, and they might look nice, but when
it's finished...
it's weak.
Look.
The issue is, in my view, that each layer is just on top of the last, rather than changing
direction, it's like building a wall with each brick over the last but not offset.
Anyway we'll check it out to see if it has been fixed in 5.2 beta in a moment - spoiler,
it has - but I guess we can see what else is new?
There is some stuff that I'll find useful, at least!
To get the beta I'll link it below, it's a parallel install which means you can just
install it to a new folder and it shouldn't, emphasis on shouldn't, affect your existing
cura...don't yell at me if it does.
This happened when I installed it which is actually annoying because I was using exactly
that profile, typically, to test with.
The cura to this problem.....cura.....whatever, the fix is to go to help, show configuration
folder and in there, go through the sub folders one by one and obliterate anything with the
name of the offending printer, while cura is closed, and that does sort it out without
deleting all your profiles for other printers.
OK change log time.
Of the flagship features unless you have an ultimaker printer, let me just check...no
I don't have any ultimaker printers, don't worry the playing field is level, I don't
have any prusa ones either..err... more control over initial layer flow.
Three new settings, yes I'm just gonna read this out like an unprepared powerpoint presentation
- three new settings, initial layer outer wall flow, initial layer inner wall flow...ohh...right.
Okay.
So if I go out of vase mode, and hunt around, took me a while to figure out where this is,
it's under material and it's set to....120%.
How is that going to counter elephants foot, is it just me or is that going to cause elephant's
foot, a reminder of what elephant's foot is in case you didn't know, it's the thing on
the end of an elephant's leg.
It's also the phenomenon where your print swells at the base due to ...well if you have
settings guide installed, it's a plugin in cura, if you don't have it you need it, go
get it, it has actually also got a troubleshooting section and if you search elephants foot it
will explain everything.
I'm not really sure if we know the actual root cause of elephant's foot, do we know
the cause of elephant's foot?
I never really thought about it.
Probably just poor z offset?
I feel like that's most of the reason?
OK let's test it, because why not, results on screen now I guess.
Given I haven't tried it at the point of reading this all I can do is just kind of pretend
there's something useful here.
Night and day, I'm sure.
In terms of other changes in this version we have something about holes in vase mode,
I guess this is something about holes causing chaos in vase mode based on the fact those
are the words used here, tree support changes, tray icon is optional if that bugged you,
nicely there's now a profile for, among many others, the ender 3 S1 which is I'm sure welcome
since we've all been using the ender 3 one and changing retraction I guess, it would
be even nicer if that can be extended to all the variants like the plus that I have, making
the seam more random, we have to talk about random z seam at some point, I don't think
making it more random is gonna solve that option but flippant remarks aside I think
that's probably the main things I want to talk about.
So in summary, new cura, it's still in beta although I dont usually have much issue with
beta curas but definitely bear it in mind, vase mode being fixed is certainly the biggest
issue for me, there's also some refinement to elephants foot prevention which could be
interesting to look closer at in the future, and some other fixes.
Is this important enough to install immediately?
I'm gonna say yes if you print in vase mode.
100% yes.
200% yes.
As I said at the beginning let me know if you found this kind of video useful, its easy
enough for me to make so I can do this in future for releases of prusaslicer and cura
or whatever else when I don't want to spend a week making a whole episode on something
including all the investigations and stuff, otherwise I will see you next time for I think
the next episode of the printing fast series!
Thank you for watching!
