Complete Cura Guide – Special Modes, Cura Tricks 4/4

Welcome to the fourth and final Cura Guide: in this last piece we will deal with special and experimental modes and some Cura tricks. I will also give you some very personal advice here, which I hope will help you.

If you have arrived directly on this page and are not ready to start with the advanced guide you can read the 3 previous guides:

  1. Cura Installation and Creation of Printers, Materials and Profiles.
  2. The Working Area.
  3. Print settings

If you have already read the previous guides or you feel prepared anyway, I hope Cura tricks is a good reading:

First of all let’s start by describing the special modes and the Experimental, after we talking about Cura tricks

Special Modes:

Basically, there are 2 special modes worth:

cura tricks

Print sequence: All at once, normally used or one at a time: With this mode you can decide to print 2 or more objects on the same plate but not simultaneously. By viewing the layers you can also follow the printing and see in what order the objects will be created.  However, you should know that the vertical printing area will be reduced to just 5 centimeters and the objects take up much more space on the plate, it is very difficult to have a printing area suitable for printing more than 2 objects.
It’s not a great mode, but sometimes it can be a solution.

Print the outer contour with a spiral-like movement: vase mode on. Selecting this mode will automatically reset the infill. This mode provides for printing without interruption, although it still has a small stop each layer (which we will discuss below how to get rid of the sign it leaves). Ideal mode for the composition of Vases even if there is no possibility of having perimeters formed by multiple walls, and therefore the print will be rather fragile.

Experimental:

cura tricksOptimization of the printing sequence of walls: this option is designed to optimize the look of the prints, but at the expense of the time of realization. This mode changes the print pritiities at the expense of the production time to achieve perfection (as far as possible). If you have time and need a great press then I recommend this mode!

Enabling the conical support: This mode allows you to create intelligent supports (even by selecting supports only adherent to the printing surface). This mode will save a lot of material by calculating the possible overhang angle and starting the support from the most comfortable point.

Hollow Objects: Simply empty the objects from the infill

Incoherent outer coating (fuzzy): Literally blurred or foggy fuzzy makes our model rough, great for aging.

Enable Ironing: Together with the ironing, we invite you to activate the option of ironing only the highest layer. The ironing process stretches the flat face of the print, making it perfectly uniform. Ironing is done by passing the hot nozzle without extruding material, so that the heat “stretches” the material, just like an iron for clothes, amalgamating and making disappear the marks of the lines. It is important to stretch only the high layer because otherwise each layer would be stretched with a printing time at least twice as long as normal.

 

And now some cura tricks:

  • By entering the cost per kg of the material during the creation of the materials you can know the price of the print we are going to create.
  • By creating 2 profiles for each layer height (one with and one without ventilation) we will be sure that the ventilation does not start disproportionately to the layer indicated.
  • When for some reason the press is interrupted at some point, perhaps near the end, if we want to save hours and hours of printing we can proceed in this way:
    measure the height of the print already created and insert this measurement (with the negative sign in front) in the displacement of the model in the Z axis. In this way we can print the missing part and glue it with the suitable glue for the type of material used.
  • By setting the thickness of the top layer to 0 and at the same time setting the filling to 0, we can transform any object into a vase.
  • With the old Cura in case of a not proportional shell to the width of the nozzle hole, it was necessary to modify the line width and material flow until a setting was found that would eliminate the problem. Today, with Cura 3.0 you just need to activate the option “Filling the gaps between the walls”.
  • If you have problems with heating failure, because when you turn on the layer fan the hotend can no longer cope with the air that normally cools must change the PID values, we also have a guide on the matter.But not wanting to go and touch the firmware settings you can also try to set this way the voice cooling: Regular fan speed: 100%
    Initial fan speed: 20%
    Regular speed at the layer: 5

CURA TRICKS – This will increase the fan’s power by 10% each layer, and give the nozzle time to manage and return to temperature even if the fanduct blows partially on the nozzle.

  • Cura 3 has a new option to eliminate the small blob of the joints, it can be activated from the entry Shell, the items to activate are:
  1. Alignment of Z-joints and joint angle preferences.
    With the first you can decide whether to set the junction in an angle that makes it invisible, or make it random or even choose the position.
  2. With the second: Junction angle preferences you can choose whether to hide the junction or expose it for easy removal in postproduction.
    The Cura tricks guide is over: I hope series of guides were helpful.
