Position of stl file in cura

Recommended Posts

Posted · Position of stl file in cura

 

Is there any possibility that cura places my imported stl file not in the geometric centre of my part but with the same origin/ coordinate system as it has in my cad design (fusion 360)?

Thank you for your help!!

Yes!

No?

I don't know...

Can you rephrase the question?

The problem is that I have one body which I spilt into two parts. I print the first part of the body. Then I want the second part printed at a certain place. In my cad design it's on the right position, but when I open it with cura it's centred in the middle of the build plate. 

 

I've already tried to align it manually and measure the distance of the different origins with my cad software but it's never exactly at the point where I want the second part to be printed.

This is where my part should be placed:

This is where Cura places it:

If I correct the position in Cura it's not precise enough

I am having the same exact problem.

I use SolidWorks and I have an assembly with multiple parts positioned correctly in the CAD but when I import the files into cura the parts when combine are in a different place.

Did you manage to find a solution?

Please help 🙂

Unfortunately not. I'm still trying to measure with my cad software. I also tried other slicers to find out if one is capable of measuring or to find the same position like in the orignal draw. But nothing out there 😕

Hi Thank you for your reply.

I have changed my model in SolidWorks so that all the bodies are now connected.

maybe you can do the same with your model.

There is a bit of more cad work to do but it seams to work for me.

See file attached.

Let me know what you think.

Hey! Thank you for sharing your solution.

I'm not sure if that will work out for me, as I have a complete part in the beginning and I split it into 2 single pieces on purpose. After the first part is printed I want to rotate the build plate and then continue printing with the second part (to avoid support material).

But I'm happy to hear that you found a way to print your part! 🙂

I’m having the same issue. Too bad the topic hasn’t received more attention. Have you had luck in any other forums?

It would be great to have an option to turn off auto centering and just allow the data to be located relative to it’s CAD export position.

Maybe you could do it with a trick? Put four tiny dots outside of each corner of your models. So that they form an imaginary rectangle that encloses your design. Or draw a custom skirt around your design; just one layer height is sufficient. Then that surrounding skirt or border should always be placed in the same position on an empty bed. Keep that skirt, or those four dots, in place, and then correctly place the rest of your components in this space, and save as separate files. When slicing, the skirt (or the four dots) should determine the position on the glass. At least, that is what I would expect. Try this with a small test piece first, before wasting too much material on a real big model.

I found a solution. Prusa slicer has an option to split up multiple bodies that come in as one stl file. Bringing them in as a single stl keeps them located relative to the CAD export orientation. After splitting they show up as a sub-assembly on the right information window. At that point you can edit the components you don’t want to print by calling them support blockers. Then switch the settings for the second run.
It’s a great way to keep components correctly located relative to each other but print separately.
