Baseline Cura Profile  

Re: Baseline Cura Profile

Hi, I am working on that. We do provide baseline settings for Sli3r in our driver package.

Biggest problem with cura now, is transferring the settings. I will probably end up forking the cure and having a binary with the baseline settings inside.
It will take some time tho.

Re: Baseline Cura Profile

With Slic3r for Mac crashing almost every time I open it and a need to shrink X & Y but not Z, I turned to Cura to find settings based on 3mm with no easy switching between filaments or print settings.

So, I was curious as to whether you were still working on a fork of Cura?

When I first started using Cura, its default was for 3mm filament. It really didn't take long to get approximate settings which worked with my first printer - a 1.75mm Chinese clone, for which there was very little help and support available.

Now, I am a very simple person who finds learning new things very difficult, but I did it and after a few failed prints, I have been able to print most things without problem.

OK, so the version of Cura that you have is defaulted to 3mm filament. So make a few changes and a load of mistakes, but you will learn so much in doing it. When you start a print, just stand next to the printer with your finger hovering over the reset button...

Re: Baseline Cura Profile

I've made my best guess and left it to it, hoping for no additional contributions to my plastic scrapyard.

Re: Baseline Cura Profile

Also looking forward to this!

Re: Baseline Cura Profile

I just bought the prusa 1.75mm kit. At the moment I "only" have an ultimaker at work, so I am looking forward to use cura also at home if somehow possible. If there are no infos till (if^^) I have my printer running I will try to work sth out and post it here... Some tips would be greatly appreciated though 😉

Re: Baseline Cura Profile

Hey,
so I actually just switched to Cura. Reason being that I could not bring Slicer to give me a functional brim so that my very small peaces dont fall off during print AND that Slicer did not let me successfully print under 0.2mm. I know that this somehow works with Slicer, but with Cura it just works 😉 I set my machine to a "Mendel Prusa i3" presetting, changed filament & nozzle diameter and was pretty much good to go. Though my first print came out with a lot of "z-wobbling" as the print time was 1/3 of my compare-Slicer part. Now with adjusting the print speed (from preset 50 to 20) the 0.2 quality is as awesome as with Slicer, but with the addition of having useful brim and the ablility to print at 0.05 mm 🙂
Another awesome feature of Cura: Stick your SD card in, he will let you automatically save to the SD file, and you have the "SD eject" button right in the same interface. Does not sound like much but if I continue with the amount of printing I do right now this definitely saves time!

Re: Baseline Cura Profile

Hi Alexander

If you are running with the standard printer firmware, make sure that Cura is set to a first layer height of 0.25mm otherwise you will get problems with the first layer.

The firmware is set with a minimum Z height of 0.23mm. There are various discussions about this on here.

Re: Baseline Cura Profile

Alexander, you must have some miracle profile and skills. I (thought) I repeated the same steps you did by using Mendel's presets and amending a few settings and this was my result. (attached)

The left is Slic3r, the right Cura. Both at 0.1mm LH. (Ignore the base, that's something else entirely).

Back to the drawing board obviously. My only reason for coming away from Slic3r was the 9/10 crashes I'd experience. More often it's the slightly more complicated models that will cause the crash but then some days a simple cube could do it. A right pain in the ass when you've just spent 20 minutes arranging models and adjusting settings specifically for that print.

I'd like to use Cura but I have some trial and error ahead of me before it'll meet Slic3r's end product. Cheers for the advice so far though.

Re: Baseline Cura Profile

Hi There

Can you post screenshots of your basic and advanced tabs plus one of the expert config screen and your machine settings screen.

I will have a look to see if I can see any problems.

Peter

Re: Baseline Cura Profile

Cheers Peter. Obviously happy to play around and check the results but always appreciate a push in the right direction.

Re: Baseline Cura Profile

Hi

First thing I noted is that you have a contradiction in terms of the printing material.

The temperatures are set for ABS and the fan for PLA. What material are you printing with? PLA: 210/50, ABS: as is. Fan - PLA: as is, ABS: 0%

Shell thickness (aka Perimeters); set this to 2 or 3 x nozzle width; reduce fill percentage - for most prints 10 to 15 % is sufficient if it is actually required.

I tend to print infill after perimeters.

Retraction on this printer only needs 1.5mm or thereabouts.

With Cura, I have a higher print speed (70 to 80 mm/s) and set the specifics on the advanced tab: Outer shell: 40, Inner shell: 60, Infill: 80, Top/bottom: 50.

Measure the filament diameter; ensure it's correct for each filament used. Flow% - this will probably need tweaking for each filament type & colour.

Minimal layer time with ABS: 15 seconds, PLA: 5 seconds.

Re: Baseline Cura Profile

Hey,
Sorry for not replying earlier, did not see the new replies...
Well, I can only agree with what Peter said. I have some experience with the ultimaker I have at work, so some mistakes were already learnt from in the past 😉 (I use pla here with 210&50°C, though I will switch to petg soon as I have very good experience with it) I nearly always print with a brim to have the needed bead adhesion.
My initial layer height is the preset 0.3 mm, which I got used to... I usually use 0.8 mm layer* thickness and infill as low as possible ( for showpieces usually 0) in contrary to Peter I print VERY slow (30mm/s outer shell, rest 40,travel speed 100 and usually set machine to 80%speed) it is weird that in your advanced settings some speeds are marked as 0, mine were not...

*edit: did not mean layer but SHELL thickness

Re: Baseline Cura Profile

Alexander

The reason you have to print slowly is because of your layer thickness (height?).

It really is best that layer height should not exceed 80% of the nozzle diameter (0.32mm) and the width of extrusion up to nozzle diameter + 10% (0.44mm).

In the advanced settings, when speeds are set to zero, they default to the main speed setting on the basic tab. I believe that this is how my Cura was set up when first installed.

The outer shell determines the quality and I believe that the general consensus on that is 40mm/sec. Inside print speeds have less effect on quality, hence mine are higher.

Most of my prints are rather lengthy (24 to 48 hours) and therefore I do tend to print as fast as possible (up to 60mm/sec for perimeter), but I do print mostly with a layer height of 0.2mm.

Re: Baseline Cura Profile

Dear Peter,

sorry I miswrote, I meant SHELL thickness, so i always have 2 line perimeters before infill starts 😉 my layer height is usually 0.2 for functional parts and 0.05 for showpieces...
I have made some tests with faster speeds and they result in lower quality. Maybe it has to do with the mechanical setup (I could tigthen some screws here and there? )

by the way i believer this method here is some good way to find the perfect settings for CURA:

Re: Baseline Cura Profile

Hi Alexander

I had a suspicion that something was wrong there; you would need a volcano extruder to print that layer height.

Personally I use 3 loops for the skin; helps with overhangs. Have you seen Josef's blog about this? http://prusaprinters.org/what-are-perimeters-good-for/

Ideally to get accurate sizing, print the outside loop first (not possible with all slicers), but when printing with overhangs, print from the inside.

KISSlicer has a simple slider which allows easy speed/precision settings. The minimum/maximum speeds are set for each item and the overall speed is set on the "Style" tab.

Yes, all printers are different and printing in different environments, using filament which has been stored differently. These are factors which determine finished quality, as well as the slicing and speeds.

Peter

Re: Baseline Cura Profile

Dear Peter,

yes I saw that post, good thing! Although I believe CURA adds some parameters himself the kind of way the simplify 3D screenshot shows in Joseph's article. So far I had no problem printing overhangs (much less than with the ultimaker at least 😀 )

Re: Baseline Cura Profile

Hi Alexander

Yes, I don't have any issues with overhangs. With bridges, I lower the temperature, increase the fan speed and print fast. All slicers tend to generate their own specific code for certain tasks, hence why I use both KISS and Cura.
