Findings model errors

[medicalmodeller 5]

Can someone kindly explain the xray function on Cura. Am I right that if I click on Xray and the model is all blue that all is well and does not need repair in NetFabb

If I click on xray and there are lots of red lines, this is bad and I need to repair the model in Netfabb? If I do repair in Netfabb is the standard repair sufficient?

Sorry if this is all too obvious

The red you see in xray is open faces. Most can be fixed in netfabb but if you start from some model that was not intended to be printed like some game model it might not resolve the issues the way you expect.

Even if the xray doesnt show anything Cura might not be able to print everything. Every surface thinner that your nozzle size + some buffer wont print. the head need to be able to reach there. Also you may have some cases where fix horrible options from the expert settings causes issues instead of resolving issues in cases where you would have a duplicated part one over the other.

Rule of thumb: Always validate the slicing in layer view before printing. You will prevent a lot of issues that way

Thanks

Without wishing to appear completely dumb, when you say validate in the slicing view, what is it that will show the errors exactly?

Here you can see a hole in the layer view where the nozzle wont pass because its too thin even if the surface is clean in normal view.

 

Here you can see that the support I added wont connect with the other side of the gap and the head will just go back and fort when printing and not make contact for that layer.

 

Here you can see a cylinder which the xray show me that its not closed. I knew it wasnt closed but when I looked at the layer view I saw that the cylinder would not even be sliced except for just a few layers.
