Cura 2.3.0 not slicing

Recommended Posts

OK I finished my software configuration and loaded a model. The message at the bottom right changed from "Please load a model" to "Preparing to slice..." and that is where it stayed. After 10 minutes I closed Cura and restarted, losded my settings Profile and the model and the same thing happened again.

Any ideas? It is a small model, centred on the bed and in 15.04.4 takes about 4 seconds to slice with same settings.

It never happened to me with a single model but I had a few times that duplicating a model multiple times and scaling some of them results in cura getting stuck in an endless slicing loop where it won't get out any more....

And as a side note, placing multiple models and scaling them is very time consuming as after you scale a model even only in z it gets moved to the centre of the bed.... pretty annoying...

Thanks for that. Just before going to bed last night I made some progress, establishing that it was a Machine Settings problem. I added another printer and chose Ultimaker 2 and the model sliced.

I had chosen a German Reprap Neo from the Other printer list and added my settings and gcode. This morning I decided to start again. Under Adding a Printer I chose “Custom printer” which I must have missed last night – not sure how as it is staring you in the face, but I did.

Setup my printer again and it all works.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
