Mach 3 Feedrate issue

Has anyone had an issue with mach 3 using the default 6"/min feedrate? It seems like a glitch because suddenly i will have no luck cutting parts, so i will load a different file, and it will work. I then go back to the original file and bingo, it loads the proper feedrate. Every time i close out the program, it resets to 6"/min and i tried to figure out what i did, but the fix is random and i cannot pin point what the solution is. I would prefer it just work when i boot up mach 3.

I’m having the same issue. Not sure what is going on. Did you find a solution?
