Cura print settings

Mon Jun 06, 2016 4:20 pm

CURA 2.3 BETA has MK2 support.

Go to https://ultimaker.com/en/products/cura-software and click the link with (beta). It is smaller under the stable release.

DO NOT USE CURA 2.1.X, IT DOESN'T WORK


Setting for older Cura 15.04.5 is here:

Don't know if you've seen but Cura has been 'updated' to version 2.1.2, a complete rewrite of the software apparently!

https://ultimaker.com/en/products/cura-software


RELEASE NOTES
Today we're proud to officially release Cura 2.1.2 after an open beta of 1,5 months. Cura has been completely reengineered from the ground up for an even more seamless integration between hardware, software and materials. Together with its intuitive new user interface, it’s now also ready for any future developments. For the beginner Cura makes 3D printing incredibly easy, and for more advanced users, there are over 200 new customizable settings.

Note: make sure to update the firmware of your Ultimaker with this new release of Cura. By doing this your Ultimaker will support the optimized material profiles in Cura.

NEW FEATURES
Select Multiple Objects
You now have the freedom to select and manipulate multiple objects at the same time.

Grouping
You can now group objects together to make it easier to manipulate multiple objects.

Undo/Redo
You can now undo and redo your actions, like moving an object or scaling.

Setting Profiles
The new GUI allows custom profiles to load easily and intuitively, directly from Cura.

3MF File Loading Support
We’re happy to report we now support loading 3MF files. This is a new file format similar to AMF, but freely available.

Intuitive Cut-Off Object Bottom
We’ve added a feature than allows you to move objects below the build plate. You can either correct a model with a rough bottom, or print only a part of an object. Please note that the implementation greatly differs from the old one where it was a setting.

64-bit Windows Builds
An optimized 64-bit Windows Cura version is now available. This allows loading larger model files.

Automatic calculations
Cura allows to set a number of lines/layers instead of millimeters. The engine automatically calculates the right settings.

Per-Object Settings
You can now select different profiles for different objects and when in advance mode override individual settings.

CURA ENGINE FEATURES
Line width settings added per feature
Global, Walls, Top/Bottom, Infill, Skirt, Support.

Pattern settings improved per feature
Top/Bottom, Infill, Support.

Shell
Alternate Skin Rotation: helps to combat the pillowing problem on top layers.
Alternate Extra Wall: for better infill adhesion.
Horizontal Expansion: allows to compensate model x,y-size to get a 1:1 result.

Travel
(Combing) Avoid Printed Parts: while combing, the print head moves around printed parts, avoiding collisions with the nozzle and a part that’s already printed.

Support
ZigZag: a new, infill type that’s easily breakable, introduced specially for support.
Support Roofs: a new sub-feature to reduce scars the support leaves on overhangs.
Support Towers: specialized support for tiny overhang areas.

Special Modes
Surface Mode: this mode will print the surface of the mesh instead of the enclosed volume. This used to be called ‘Only follow mesh surface’. In addition to the ‘surface mode’ and ‘normal’, a ‘both’ mode has now been added. This ensures all closed volumes are printed as normal and all loose geometry as single walls.

Experimental
Conical Support: a filament cost-reduction feature for support.
Draft Shield: prints a 1-layer wall that prevents air from hitting the print, reducing warping.
Fuzzy Skin: prints the outer walls with a jittering motion to give your object a diffused finish.
Wire Printing: the object is printed with a mid-air / net-like structure, following the mesh surface. The build plate will move up and down during diagonal segments. Though not visible in layer view, you can view the result in other software, such as Repetier Host or http://chilipeppr.com/tinyg.

REQUIREMENTS
Mac OSX 10.7 or Higher
Windows Vista or Higher
Ubuntu 14.04 or Higher - Only 64-bit versions
Cura requires a video card that supports OpenGL 2 or higher.

SUPPORTED 3D PRINTERS
By Ultimaker: Ultimaker Original (no dual extrusion support), Ultimaker Original+, Ultimaker 2 Family, Ultimaker 2+ Family.
By 3rd parties: BQ Prusa i3, BQ Witbox, 3D Maker Starter, RigidBot, Malyan M180, German RepRap Neo.
There is no dual extrusion support in Cura 2.1.2 yet. Users with an Ultimaker Original who installed the dual extrusion upgrade kit, can use Cura 15.04.

OTHER NEW CURA ENGINE SETTINGS
Shell
Top/Bottom Thickness: can now be changed separately!
Extra Skin Wall Count: add extra walls to the top and bottom layers to improve roofs that start on infill material.
Remove Overlapping Inner Wall Parts: remove narrow pieces that cause over extrusion on prints.
Compensate Wall Overlaps: compensate narrow pieces causing over extrusion on prints.
Fill Gaps Between Walls: fills the tiny gaps on narrow prints pieces.
Z Seam Alignment: allows you to choose the z-seam location.
Ignore Small Z gaps: if unchecked, fixes small Z gaps.

Infill
Infill Wipe Distance: allows you to increase infill overlap without over extrusion on the shell.
Infill Layer Thickness: choose a separate layer thickness for the infill to save time on prints.

Material
Retraction Extra Prima Amount: allows you to compensate for oozed material after a travel move.

Speed
Number of Slower Layers: sets the first layer(s) speeds to increase build plate adhesion.

Travel
Coasting: prevents oozing by replacing the end of print paths with a short travel move.

Cooling
Regular/Maximum Fan Speed Threshold: Allows you to set the time a layer must take to linearly go from Regular fan speed to Maximum fan speed.

Support
Stair Step Height: allows the support to lie tightly on top of objects, increasing support stability.
Join Distance: allows supports to become one, increasing support stability.
Horizontal Expansion: adds extra support to the x,y-directions, increasing support stability.
Area Smoothing: smooths the outside contour of support structures to minimize resonation of the print head.

I was printing a part I converted to gcode in Cura and the printer did not perform self test before printing and was printing as if bed was out of level. How do I fix this?

Be careful using Cura 2.1.2 with the i3 MK2! I tried it, and found a bug that I think caused an extruder jam.

Regardless of what profile you're trying to use, Cura 2.1.2 seems to ignore changes to the retraction setting, and always reset it to its standard setting of 6.5mm, at least for me. This is far to much for the i3 MK2 (0.8mm is recommended), and I believe this causes soft filament to travel up into the heat break, which then cools and can jam the extruder pretty badly.

If you do try Cura 2.x, only use it if you can get the retraction setting to stay on a value under 1mm! Check it by saving the profile, switching, and switching back. It may look like it's set one way, but not actually save the setting. Better yet, just don't use it for now, use 15.x instead.

EDIT: Found a bug report page with a possible fix. Use at your own risk.

I made some Cura settings for 15.04.6 for PLA at 100 microns and 200 micron layer heights.

Give it a try and let me know how it works for you.

That's great, thanks. I would just mention that some people on here are getting nozzle blockages with retraction set to 1.5mm and I believe the Slic3r profiles now have this set to 0.8mm.

As of now Cura 2.1 on a Prusa MK1 or maybe even a MK2 ( Don't have on...Yet!) just hasn't been working too well for me. I have no problems with 15.X since I've been using it while printing. Not sure If it perhaps just needs some more tweaking due to all the additional settings and being a total rewrite of the original software. If anyone has had any better luck or info with their experiences with 2.1 please chime in.

DO NOT USE MK2 WITH LATEST CURA.

just finished my build. Done all calibration. Printed a nice whistle and my calibration Z's. Use Cura to print an object and now have a gash in my brand new heat bed. Peed off is an understatement. Waiting over 4 weeks for the printer and first print has ruined my printer :x :cry:
