Cura not using user set machine print head size

[sniped1928 0]

So I am trying to print multiple objects, one-at-a-time, however cura is using some preset dimensions for the printhead size and I can't figure out how to turn it off. as you can see in the photo you have two print head dimensions being displayed, and cura is using the much larger one even though it's not really the case.

Hi @Sniped1928,

welcome to the Ultimaker community!

What version of Cura are you using?

In the latest version, Cura 2.4.0, you can go to settings > printer > manage printer > machine settings; and there you can find the printhead settings. You should be able to alter the settings to match your actual printhead. I think that should change the reference in Cura.

Let us know how it goes!

They are not really print head dimensions. The smaller grey oblong is the area that you are printing, I assume you are using a brim.

The larger grey oblong is there because you have selected "Print one at a time". If you change that momentarily to "Print all at once" you will see the larger grey oblong disappear.

If you select "Print one at a time" then Cura will spread out your models to ensure that when you print the 2nd model the print assembly does not hit your 1st model - not relevant if "Print all at once" is used. The grey area represents a no-go area as far as another model is concerned.

The size of the larger grey oblong is determined using the dimensions stored for your printer and yes you would want to change those if you are using a non UM printer - as per @SandervG instructions above.

Whether or not the larger grey oblong is exactly the same as your print dimensions I know not, but they will be close.

I have been having trouble with "print one at a time" in CURA 2.x and this is what I am seeing:

A. The larger grey box does not correspond to the machine head size settings. There seems to be a bug. It randomly chooses either one of the Xmin Xmax Ymin Ymax settings and draws the larger box using that value.

B. Cura will not auto-move your objects to avoid crashing the head into previously printed objects. (probably due to A)

C. Even if A worked correctly, it would be hard to manually place objects since both shaded boxes disappear while moving the objects around.

SO - for now, if you want to use "print on at a time" then download CURA 15.X which has none of the above issues.

Hi there...

I tried in Cura 2.4 there is no way...?! --->

in Cura 2.6 it seems to be ok....

I can only use Cura 2.4 , cause the representation of the graphic for "layers view" does not work (Open GL etc...) The "compatibility mode" is'nt just fine )-:

...any help?

Cura 2.4 did not support Machine Settings for dual extrusion printers. Cura 2.6 does.

Newer versions have newer features.

Can you clarify "The compatibility mode is'nt just fine )-: " ? Compatibility mode should look just like layerview in Cura 2.4.

Hi, thanks for the answere....

Can you clarify "The compatibility mode is'nt just fine )-: " ? Compatibility mode should look just like layerview in Cura 2.4.

hm ... no, it does not.. the lines in the grafic are not highlighted.... like in Cura 2.4

---->

Am I doing something wrong? I guess my graficcard does not match? I tried to upgrade it, but without any results.... :(

[ahoeben 1,951]

If your GPU does not support the new layerview, it will automatically fall back to compatibility mode, no matter the setting in the general preferences.

I'm not sure why the top layers are not showing up for you. Please report this issue at https://github.com/ultimaker/cura/issues

I cannot seem to get the "Print Sequence" options to open up for me even though I have all the3 settings checked to be open.

Even when I have two models loaded and look in the per model settings, it does not show. What am I doing wrong or missing here?

...as far as I have learned here in the forum, 'these options are not able to set with 'dual-extruder-machines'

... and your UM3 has two extruders?!

maybe this thread helps : "Print Sequence" options ----->

That is what i thought, but then I saw this and misunderstood:

Cura 2.4 did not support Machine Settings for dual extrusion printers. Cura 2.6 does.

Newer versions have newer features.

Can you clarify "The compatibility mode is'nt just fine )-: " ? Compatibility mode should look just like layerview in Cura 2.4.

My goof entirely...
