[CURA and Artillery Sidewinder X1 calibration issue]

3D model that was located in CURA at the middle of the cube floor, was printed in Artillery Sidewinder X1 at the front left edge, in a way that exceed printing bed.

Any idea what did I miss?

My advice:
Rotate model for 90° in X or Y axis and you'll get better results.

In your situation, i would rotate model for 90° (Left surface (on your image) align to the build plate).

 

Sounds a simple change and good idea. I'll try it, but it couldn't be a work around for printing a ball …

Large radius objects are tough.  The angle is severe at the lower layers causing the printer paths to be far apart and they don't want to bond.

I think I'm in agreement with @Longtoke regarding moving the ball up off the build plate (2mm sounds good) and letting the underside be all support structure.  I know it won't leave a great finish, but it should print.  Another thing to try would be Adaptive Layers.  

I have already used adaptive layer in the described issue (max variation 0.2, variation step size 0.1, topography size 0.1)

Very odd....

 

I tested the issue by creating a basic sphere ( 80mm diameter ) and using a basic cube base of 100mm x 100mm x 50mm to losely replicate your model, but a very low res version Tremendous Wluff.stl ( made with tinkercad ). 

 

Did the slice on a 0.2 layer height and the same odd pattern appears in the low point center ?!?!

 

It looks like Cura is getting confused by the shallow gradient of the curve at the bottom ( note the tell-tale concentric walls in the preview ).

 

Now really weirdly, even with the concentric walls, the layering still seems correct ( from the Cura preview ) on the low res poor mans version I did anyway. From the look of  your model failure, I'd suggest having a few layers of material below the lowest point of the sphere, as it looks as though you've  had adhesion issues due to the mix of small concentric walls and diagonal fill. Even a 2mm layer below it could be enough to sort it. 

 

Good luck and let us know how you go. 

Layer height is 0.2mm, the odd pattern appears in the low point center. I face the same issue when printing a ball …

[printing ball issues]

Hello

I am trying to print a mold for a flatted ball (see "half mold" image). The resolution of the model is high (about 1M points, the STL file is about 100Mb - too heavy for sending...).

Cube areas are sliced and printed perfect.

Flatted ball areas are sliced strange and printed badly (see "sliced image" and "flatted ball...").

On printing a ball, I have faced similar issues.

Are there any special parameters / method for slicing a ball?

Any idea what I am missing?

Thanks a lot

[mold option issues]

Hello

Attached please find a photo (name – s26) of a sculpture model I am trying to print as a mold. The second photo (name – "s26 print") is the inside view of the printed model.

As you can see, I am facing 2 main issues:

·      The print includes some holes. I think it's a result of lack of support. I couldn't add support inside the head (neither automatic, nor manual (Support blocker)). If it's possible, please let me know how.

·      The inside part of the head includes strings from wall to wall (bridge wasn't selected)

Both issues (holes and strings), prevent using this print as a mold.

·      How does mold option works? Does it create the model negative or just expand the model within mold width?

·      I didn't find a way to create a mold with 1 layer (meaning – the distance between the outside of the mold and outside of the model is - 0 mm). I intend to cast cement in the mold, therefore I want a minimal mold width

Is there a reason why Cura does not support slicing of an open model (like the attached one)? Load it to Cura result by the following error – "your model is not manifold. The highlighted areas indicate either missing or extraneous surfaces". Is there a way to do it?

Thanks a lot

[Slicing issue creates flat surface instead of convex surface]

Smaller layer height and adaptive layers improve slicing but double time printing …

Any other ideas?

[Slicing issue creates flat surface instead of convex surface]

Hello

In the attached image please find the problem I am facing.

The middle image is a clip of slicing result of the 3D model. The upper and lower images show the mesh of the relevant parts. As you can see, a very nice mesh is input to the slicer (v4.6), but slicing at the marked area is not densely located. As a result, the printed object (at those areas) is flat and not convex (as it should be).

Any idea how to improve slicing?

Thanks a lot

[Calculated / actual printing time]

Thanks for your response.

I am new in the 3D printing area and was not aware to those parameters (acceleration control & jerk control). Do you recommend enabling them? Are there any guidelines regarding the circumstances that it's worthwhile to enable / disable them?

Regarding the default parameters, I didn't find the exact naming, I found the following:

·      In the EEPROM:

o   X-axis-acceleration – 20

o   Y-axis-acceleration – 20

o   Z-axis-acceleration – 50

o   Max Jerk – 5

o   Max Z-Jerk – 0.3

·      In the H file

o   Extruder max acceleration – 5,000

o   X Travel acceleration – 1,000   (same for Y)

o   X print acceleration – 1,000   (same for Y)

o   Z Travel acceleration – 1,000  

o   Z print acceleration – 100  

  Is it the same?

Thanks a lot

[Calculated / actual printing time]

Hello

I am using Cura for slicing and facing the following strange phenomena:

1) Actual printed time is about twice than the calculated printed time (by Cura)

2) Double printing velocity doesn't cut printing time by half. It cuts it by 20%.

Any idea why?

Thanks a lot…

[gradient infill]

Hi

Thanks for your response.

Unfortunately, I am not in the SW details anymore …

·       Can you send me detailed instructions what to do in order to be able to use your infill functionality?

·       Does your "Cura-mb-master-win64-20200328.exe" replace the "Cura.exe" with all its functionality?

·       I am using Cura 4.5, and my printer is running by arduino - Atmega2560. Can I run your application in this environment?

·       PI 4 – means - RASPBERRY PI 4?

·       Where should I find the libgles-dev package?

Thanks a lot

[gradient infill]

hello

Is there a way for infill in varies density – high density near the walls (shell), low density in the center of the model? Is it possible to define the level for high / low density?

[hollow an object]

Yes, I am trying to get CURA to do this.

If I am printing an object and want it to be hollow, why not defining shell thickness and print?

Let's presume that we have a model of a glass that we want to print. Will I be able to define shell thickness and print?  So why not if it's a box?

[hollow an object]

Hello

I want to hollow an object, leaving a shell thickness of about 10% . The shell will be composed of - first shell, infill, and second shell.

Is it possible?

How?
