For some reason after I do a tool change the feedrate override will sometimes increase....has anyone seen this before?

  OK...just found out that F10 is both tool clamp AND feedrate override. I had not realized there were keyboard shortcuts for feedrate override when I assigned the tool clamp/unclamp. My bad.

That is a classic example of why I personally dislike using HotKeys.
I think Klaus's MachScreen programme tells you if you have duplicates or possibly it gives a list of what you are using but always worth checking if you plan to use HotKeys.

Thanks for the input....I will look into that. One more thing that happens once in a while is if I hit stop (not e-stop) while running a program I lose jogging. Have tried to disable/enable jog mode but nothing. Even have tried MDI and the DRO moves but not the table, then the DRO goes back to where it was. After hitting and releasing E-stop all is good again. I am using a third party motion board, made by ajax. Any thoughts?
