I’ve been bittern by this more time than I care to admit.
When a new file is loaded, reset the feedrate.
I frequently run a file twice (once for cutting, once for a quick clean-up pass), and the feedrate gets set to 150% or 200% for the second pass. Move to the next thing and whoops that doesn’t sound right, quick, reset the feed rate!
If people need to run multiple files all at an increased feedrate, well the right fix for that is to fix your feed in your design program.
