i have tried this xml on 3 different computers with same result when you start Mach hit reset then go to MDI screen and type in a move its still slow as, but you can jog with key board or fly out screen that run at correct speed and if you load a g code that will work ok its just when you type in a move in the MDI screen after you start up this problem exists, if you hit stop or verify before inputting move its gone.

I tried that and it made no differences what its doing now is if you jog after start up that ok, but if you type a distances to move in the mdi screen its really slow then if you hit verify it come right its something i can live with
