Model not visible in Cura's Layer view

[douwedaki 0]

Dear forum,

I have been struggling lately with lots of my .stl models not showing up in Cura's layer view (while being perfectly visible in the other views). They have mainly been models made in Sketchup but I've had it with models made in Rhinoceros 3D also. All models were very flat, simple prints, for example 150 mm x, 150 mm y, 0.3 mm z (so very flat models). Myself I am using Cura 15.02.1 because my laptop (MAcbook pro 10.6.8) cannot handle newer models but I just had the same problem on a different computer (Windows) with the newest Cura installed. And when they do not show up in Layer view I cannot save them as gcode either. Anybody any idea how to solve this? Thanks in advance!

For the model see:

Kind regards,

It seems to be that the model is too thin to print. If you increase the Z scale to 2.0 it does print.

Hi Nallath, thanks for your reply. The thing is I am printing lots of models with exactly the same hight, 0.3 mm, and they print fine, but say 20 percent of the models (so all .3mm thick) aren't visible in the layer view...Why oh why? it seems to me this is a bug in Cura....

Did you try changing the first layer height to 2.5mm? I think this has to do with a bit of rounding issues.

I downloaded your Model. It can't print because your Model is too big for my Ultimaker Original Plus print bed. You can see when your loaded Model STl file Looks Gray not Yellow it is to big or out of the print area.

Under Machine Settings you can see 205x205x200 mm print area. Your model file can't be more than this size. Allso do not forget Nozzle can touch right back glas retainer. You should also calculate with Skirt line (Default Setting in cura 3mm away from model) around an Object. For me X 195 Y 195  Z 200 mm is possible

Yoru wrote 150 mm x, 150 mm y, 0.3 mm z but Dropbox Stl file is over printbed size. I scaled down to %0.9 Cura was able to calculate.

Thank you both for taking time to reply! Your answer solved the problem Niyoki. I wrongly presumed the maximum model size would be the same as the size of the build platform. Now i just rescaled the model like you said and it worked fine!! Such a simple solution for so much headaches. Thanks a million!
