In other words without giving up a feedrate. For example I want to move an axis twice in 2 different feedrates, but the speed doesn't matter to me (only the time it needs): G01 F1000 X0 G64 G4 F1 Move X to 100 in 2 seconds Move X to 500 in 2 seconds. Is something like this possible? Greetings, Jordie

Thanks CNC600 the keyword is: "Inverse-time feedrate" (G93) The F-value represents the time, based on minutes. Watch to the attached screenshot with a sample.
