Cura 2.5.0 and Tweak-at-Z post-processing


Recommended Posts

Posted (edited) · Cura 2.5.0 and Tweak-at-Z post-processing

Hi all,

I just had a case where I need to slow down the print speed at a given height for better bridging. In the past (maybe as early as Cura 15.04 but probably also with a previous 2.x version) I have successfully used Tweak-at-Z for such purpose. But for today's attempt with latest version 2.5.0, my Tweak-at-Z instructions don't seem to be really applied.

I use Cura from the official AppImage under Linux OpenSuSE Leap 42.2, if that matters, and this is on an Ultimaker 2+ with default "fast print" settings.

My exact settings: I tried to set print speed at 50% starting at layer number 379 and keep value for 4 layers. The post-processing icon (hammer and wrench) was present near the "save file" button. The resulting gcode actually has comments like follows:

 

;POSTPROCESSED;TweakAtZ instances: 1;Generated with Cura_SteamEngine 2.5.0

 

...but when I look at layer number 379 and following, I don't see any change in print speed (assuming this would be reflected in instructions like "G1 Fxxx").

Am I missing something or doing something wrong?

Can anybody confirm that confirm that it is still possible to tweak speed at select layers with Cura 2.5 (and explain how to set it up)?

Thanks in advance.
