Haven't we all! My normal process now is to add 8 second delay to the G-code after starting the spindle to make sure it comes up to speed. As the same relay starts the dust extractor I cannot hear the spindle start but keep a wary eye on the VFD display to make sure it doesn't stay at 00000. 8 seconds is enough to realise I've done something stupid and stop the cut before it starts.
