@dc42 I am using prusaslicer, but I do have multiple configs and sometimes forget which one I'm supposed to be using - I will check for what units it's using. Thanks!
In Prusaslicer there is an option for how to use the acceleration and speed settings that you configure. Set it to use those figures to estimate print time but not to write them to the GCode file.
