Cura: Mutiple nozzles for one print?
-
Has anyone tried or is it even possible, to print multiple nozzle sizes in Cura? I am talking about a small nozzle for the outside to get resolution and a fat nozzle on the inside to get speed?
This would be with a tool changer system such as a Jubilee where I could have a 0.3 mm nozzle for resolution and maybe a 0.9 mm nozzle for speed.
Related question: how about multiple layer heights? 0.1 mm for the 0.3 mm nozzle and 0.5 mm for the 0.9 mm nozzle?
Does any current slicer support this kind of a print ? -

PrusaSlicer does, but with a few minor exceptions.
- the version I use always slices the skirt with 'extruder0-width' which goes wrong if you only use the big nozzle for 1st layer.
- the layerheight for the big nozzle is always a multiple of the basic LH (print infill every n layers)
- you can't use a wipe tower with different nozzles.

That doesn't see like a problem, just set extruder0 to be the 0.3 mm nozzle ... unless I am mis-understanding something.

That seems reasonable as well hadn't thought of doing it that way. With Cura, all extruder layers are the same height

Not a problem
Thanks I will check out PrusaSlicer

Trying to print a 0.3mm wide track with a 0.9mm nozzle leads to failure. The filament wont stick well and winds up around the nozzle.

@o_lampe, I wouldn't attempt to print a 0.3mm wide layer with a 0.9 mm nozzle. The idea is to set extruder0 up with a 0.3 mm nozzle and extruder1 with a 0.9mm nozzle. Print the outside with the 0.3mm nozzle and print the inside with the 0.9mm nozzle.

Does any current slicer support this kind of a print ?Cura supports this fairly decently
- You can select which nozzle/tool prints the outer and inner walls
- You can select which nozzle/tool prints the infill
- You can choose which nozzle/tool prints build plate adhesive (raft, skirt, etc)
- when printing support, you can select which nozzle/tool prints the Infill, First layer, Support Roof, and Support floor.
Its quite easy to change the line widths for each 'feature' (infill, outer walls, etc) under the 'Quality' section in Cura. You could set your .3mm and .9mm widths there. You also will select your baseline layer thickness.
In the 'Infill' settings, you can select your infill layer thickness (must be a multiple of the layer height - if your baseline is .25mm, your multiples could be .25, .5, .75... etc). Similarly you can do the same for support layer thickness.
-
@sebkritikel, thanks. I was not aware that I could do different line thickness for the infill. I thought that all lines of all extruders had to be the same thickness.
-
@jens55 if you’re feeling adventurous, I recommend making ALL settings visible. Lots of stuff going on in the background of Cura with how some of those settings are configured.

If you're feeling really adventurous try Cura Master: https://github.com/smartavionics/Cura/releases/tag/20210629
Cura is a very powerful slicer once you take the training wheels off and really dive into the settings.

@phaedrux, I use the Cura-MB build
-
In that case, If you try PrusaSlicer you might also like to try SuperSlicer.
-
@phaedrux, OMG .... I am an old fart, most of what goes into my brain falls out the ears because grey cells have become an endangered species and nothing 'sticks'.
I have looked into PrusaSlicer and I kinda like what I see although I am reluctant to take on the learning curve (I will probably do it gradually by intermixing Cura and PrusaSlicer). Mentioning yet another slicer falls under the broad heading of 'cruel and inhumane'Edit: I take it back - didn't realize it was a PrusaSlicer fork .....

If you've already endured Cura for a while Prusa slicer/Super Slicer will be a walk in the park. The Gui settings can also be gated with beginner, intermediate, advanced, and the stock profiles are good starting points regardless of printer usually. It lacks the sheer number of knobs that Cura has to twiddle.

@phaedrux, Cura's knobs are indeed a huge challenge
