Hi, need some help getting TweakAtZ. Nothing happens if i go to Extension > Post-Pros > modify g-code. Nothing comes up or open when i click 'modify g-code' In C:\Program Files\Cura 2.1\plugins\PostProcessingPlugin\scripts i can see PauseAthight and tweakatz.py there. Cura 2.1.3. Tried reinstalling but same thing, nothing happens when i try to open 'modify g-code'. // Martin
