Does somebody know a SIMPLE WAY to change the 10% feedrate step to a lower value (e.g. 3%) in MACH3.
I use MACH3 plasma setup, and in MDI screen, F10 and F11 may be used to increase or decrease feedrate by 10% step.  But this step is too big, as we use oxy-propane torch, and feedret must be adjusted very precisely in 2% to 3% increment only.
I suppose this paremeter may be modified somewhere in a configuration file, but i don't find anything about it.
Any help welcome.

Push your tab key if your running the default screen set and a mpg page will pop out.  Enter your slow jog percentage there and push the tab key again and the MPG page will hide again.

If I understand what you are wanting then I used to do similar with external buttons before I started using a pot via analogue inputs to Mach.
If you dont want to use external buttons then you could either open the screenset in one of the screen designers and add two VB buttons to your screenset or change the Up and Down buttons to be VB buttons.
 You would then put some VB in those buttons, maybe something like this for Down button


FRO = GetOemDRO(821)
Decrease = GetOemDRO(821) - 2

SetoemDRO(821,Decrease)

and for Up

FRO = GetOemDRO(821)
Increase = GetOemDRO(821) + 2

If FRO= 0 Then
SetFRO=1
Else
SetoemDRO(821,Increase)
End If


If you need further help in doing this just shout.
