[Problem with cura i can't figure out]

I do not think it is Cura as it just may be more sensitive.

Can you up the model you made and let me take a look?

Thanks!

I went in the meshmixer file and it seem the problem starts here. This haven't been a problem before so i'll have a look into it.

Sorry about the file. It's one of my earlier works, so it is a little messy after going through the fixer and then being cut in meshmixer. none of these programs are online. 3d builder which is integrated program in win 10 for fixing the object and can be used as a slicer.

You are quite welcome :)We all have to start somewhere and it is almost always the easiest thing that goes wrong. As you build you knowledge and successes, things will become easier. Although, to be honest, failure teaches me more as I never know if things go right because I got it right or got it lucky.

Good Luck!!

haha xD success shorted lived >.<

I am beginning to belive this is a bug i cura now. I have done what you did, but in cinema 4d that i use.

to show they are connected:

I combined those two parts and fused them togheter to be a watertight object. The error is still there when i export it as obj and place it in cura 2.5.

Yours on the left and mine on the left:

But whats intresting is that when i put it in cura 15.04.6 it places on the buildplate just fine.

Cura was not the issue. It was the model. Here are the steps to identify and fix without getting into specifics as each package used will be slightly different, but the procedure remains the same. And, this is why I rarely use online models. It is almost as much a pain to fix as to build properly from the beginning.

And the fixed Helmet piece that I did to check it with:

It sounds like you may have a 'floating vertex'. I have found that personally exploring the model in all its parts to be more efficient than trusting software to automate the process. I find things that software often misses. And, sometimes, software finds things I miss.

Edit: I did some tests and Cura will ignore a single, unattached vertex. But all one vertex needs to be out of alignment to throw it off is -0.25MM.

But, I wonder if maybe you have the brim, somehow, turned on to put it under the model and not just outside or some weird action with the model itself.

But, I cannot replicate the issue by creating a new object. Would you be opposed to putting the model up for someone to inspect?

I also notice that it is the support you mention. I am trying to replicate this and I have not been able to. But, I remember support being placed under an object a while ago and for the life of me, I cannot remember what I did that got rid of the problem.

Here you can have a look and see:

All it takes is one vertex to be out of alignment or just enough tilt to throw it off.

But, to be clear, does it only happen if the support is on? If you slice without support, does the model sit cleanly on the buildplate?

In such cases where it does sit up off the plate, rowiac stated, you can just move it down slightly, but to do so easily, go into preferences and turn off 'drop model on buildplate' or it will fight you. But, you will get great response to that and be able to type in negative distances.

This model have been through 3d builder to fix any problems with the model then put in mashmixer to be cut to fit the bed.

I have placed the flat side down. When i turn off support the model sits cleanly on the buildplate yes.

I am aware of that i can go negative in z axis, but it is very annoying to have to do this to every part...

Hello!

I have an annoying problem with the support in cura. When support is on it causes that you can see in the images. It places support under the model for no reason. Cura places the model for som reason a little bit up in the air. When i turn off supports it places the model at the buildplate as i want it to, but i do need the support too.

Can someone help me with this problem? Is it a bug?
