Btw when you created a new filament for the reality filament did you add in suitable linear advance values to the custom gcode section of the filament ?
One of the reasons that the filaments are vendor locked is that they contain tested LA values for the Prusa printers. When creating or copying your own you have to make sure all these things get configured. Generally though you can copy the linear advance values from a similar filament that is tuned for your printer and have a close enough for use.
That's a silly way of thinking. Printer doesn't know what type/brand of filament you're using. All needed parameters are in slicer and you just need to find the right values -these values don't only depend on your particular filament, but also on object you print.
Why would you decrease extrusion, if you only have trouble on first bottom layers? Think... why only bottom layers expand? Maybe because it's too hot below... or maybe you should change "Elephant foot compensation"... or maybe Creality filament is more "difficult to print".
And finally, why are some of us ready to pay slightly more for filament? Because, if 20% of objects printed with cheap filament land in bin, we end up cheaper actually.
there is this phrase "there are no silly questions". perhaps you want to elaborate on what part of those two questions are you referring to and why. let me clarify in advance: I went from "there is not Creality filament profile in Prusa Slicer because no one made one for an unknown but also not so relevant reason. I assume laziness combined with lack of need" to "oh, there is a Crality filament profile in Prusa Slicer but it was hidden from me for some reason.". hence my initial assumption for a reason why I do not see a Crality filament profile was invalidated.
reasons 1+3, I can work around and arrive at a solution. reason 2 however means that since Prusa (with their vast resources and experience) could not do it, I can not do it. hence I shall stop wasting my time trying. I don't think this could be classified as stupid.
glad that you asked: the expansion coincided with the bottom layers and I measured the filament at 1.82mm (just one point of measurement) and the area of a circle with a diameter of 1.75mm is 92% of the area of a circle with a diameter of 1.82mm. so changing the extrusion rate was a path worth exploring imho.
temperature is another thing I'm currently investigating. my motivation for this post was not "help me to get this filament to behave", I will figure that out eventually and hints are always welcome. the bigger part of the first post was to illustrate what led me to the question in the last paragraph.
So, I use the cheap stuff for prototypes and Prusament for the final print. my design skills are not really good yet, so I do a lot of prototyping and a lot of the prints go into the bin but not because of the print quality. suffering from a few drawbacks can be justified in this case.
The only caveat to Bogdan's points is filament width and the ptfe bowden tube. The mini is a bowden printer and the ptfe tube that carries the filament to the hot end is specified with a certain internal diameter. Filament with poor quality control can vary the width quite a bit. If it gets too wide then that can introduce friction into the feed path (even though ptfe is 'slick'). This doesn't help with smooth feeding.
Instead of altering your extrusion multiplier you really need to make sure the filament diameter configured actually matches the measured average of the real filament using a set of calipers. Most people forget about that step. If you have 1.75 in there and the actual filament is 1.76 then its going to over extrude. If the diameter is thinner then it will under extrude.
Just to clarify.. by saying "silly", it's meant "unreasonable" (and not stupid).
Ok, for whatever reason, Prusa didn't include profile for your filament. You have three choices: find settings by yourself, you get settings from someone who successfully uses that filament on the same printer, or you decide for another brand.
I never tried Creality filament and I don't say it's a "bad" filament. But if I wouldn't get decent result at "normal" settings, then I would move to another brand -simply as that.
Yes, Prusament PLA is very expensive (it's good, but overpriced in my opinion). But there are other cheaper known brands, maybe few euro more expensive than Creality. I tried AzureFilm PLA, which is less known in this forum, and I got quite good results -and so I decided to stick with it for now.
lowering the temps reduces the high expansion and rising the z level my 150m completely fixed the elephant foot for the prusament (I did not touch the temps there) and reduced it greatly with the creality.
and the k values for thew mini are quite different than the ones for the i3. I guess I won't do this any time soon but I also don't feel the need to do so at this point in time with the creality filament. would be nice however to do this in the future just for curiosity^Wscience.
I have made a test print object (XY size about 50x50mm), where I changed K value from 1.0 to 3.0 (in 0.5 increment) every 4mm in height. And honestly, there was no visible change in print result. That is, I expected to see changes in corners, where print head rapidly changes direction. I also increased print speed slightly to provoke K impact more, but again, no visible changes. I have also examined resulting G-code, to make sure that desired K value from custom G-code, is actually implemented -and it was.
This makes me thinking... Maybe Mini doesn't read/use K values from G-code at all? That would also explain why I couldn't find any LA test print (custom made for Mini) on the web.
Ok, it's also possible I didn't make my test print properly. So, if anyone successfully experimented with LA on Mini, I would be happy to learn.
thumbnail not showing on Creality 3 V2. Hi, in Cura I've selected extensions and added create Thumbnail, sliced and saved. But a thumbnail does NOT show on the creality 3 vs 2. If I use the creality slicer it does, but Cura seems a bit better. Is there a way to get Cura to add add a thumbnail that will show on Creality 3 V2? Cheers Steve
If you compare the cura & Creality gcode files created when you slice you'll see that the Creality slicer puts the thumbnail at the top of the gcode, where cura puts it further down, which is one reason for it not working as it needs to be the first item in the file. I also think the cura thumbnail format isn't correct for Creality printers either . There's a couple of ender specific post-processor scripts in the cura marketplace, which may work for your printer.
I tweaked one of those store post-processing scripts designed for the neo v2 to get the thumbnails working on my S1 Pro, but the screen on my printer is different to the one on the Ender 3 V2 so it probably wouldn't work for your printer
are you using any other post processor scripts? the line with ; jpg begin 300*300 needs to be at the top of the gcode file & some other scripts override my script. open the gcode file in notepad & check the ;jpg begin 300*300 & jpg end are in there with the thumbnail code in-between
I think that may be more of a cura issue than the script. With the last couple of versions I've had situations where even the simplest of parts would slice then I'd make an insignificant parameter change & it wouldn't slice. The simplest fix for me was to either move the part on the build plate or move & re center & it slices fine the next time.
Still trying to get this to work. It works when slicing it to the Creality slicer but the Creality it's so glitchy... would love to use this on Cura. Any other solutions or newer file update for Cura 5.6.0
LOL was trying Creality Print so I could see what the difference in the gcode files was, even it couldn't produce a valid thumbnail for my E3V3SE. Updated to latest version, saw "STL Thumbnail Generator" or something is one of the install options (so of course I selected it). Loaded a model and...
See! I told you it was there! Why it appears to be on a significantly smaller build plate... that I don't know. I'd delete it, but... can't seem to select it on the preview tab and in the prepare tab I go Edit > Select All Models and it ain't there. Figured I'd try again, go to File > ...hang on, there isn't a "new project" option. None of these options will clear the build plate. Fine, close it, reopen it, add model...
No search. That's useful! Also, I can't but notice that even Creality don't set the head size correctly. This thing has a massive noggin! I measured it! And I got [[-40,20],[30,20],[30,-60],[-40,-60]]. Fine, turn on advanced mode, search through options...
