Cura 3.4.1 won't end the slicing

Recommended Posts


I have installed Cura for the third time, deleting all de necessary cura maps (the profiles also).

What do I do:

1. Start Cura and choose my printer (TevoTarantula); change the board size.

2. Set the visibillity settings to advanced, without changing anything yet

3. Load the print figure from Thingiverse

4. Hit the Prepare (slice) button



- Cura shows a screen with the text slicing .... (see jpg attachment)

- The stderr.log file shows me different?? (see jpg fragment and full text attachment)




Can someone tell me what's going wrong. In the earlier version I didn't have this problem. I have a Windows 7 machine.


Thanks for any reaction in advanced ?

I discovered that Cura on my business laptop does operate fine and slices the example above without problems. I remember that my graphic card was update a short time ago. So I think the problem has to do with the graphical interface.

I'll try to downgrade my driver version and will test Cura again...

An important update

I have been tuning my PC and I thought "maybe when I shut down my ZoneAlarm". And what happens... I see Cura slicing again.


I'm very happy about that, but that leaves me thinking about it.....  


So my question to the developers of Cura is "what has been changed that the new version needs to make contact with the internet?" . 

I'm using Cura almost two years and never had this problem with ZoneAlarm active.

    • "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.
