Ok so I have operators in my shop that want to slow the machines down too far for certain jobs.  Is there a way to limit how far down you can turn the feed rate?  I want them to be able to turn it down to 80%, but no farther than that.  Then the job just takes too long.  I've tried explaining this to the operators, but they don't get it, they continue to do this. 

You could have the macropump set a minimum override value. For example if the value entered is less than 80% the macropump would over rule it and set it 80, if greater than 80% then it would leave it alone.

If you edit the screenset in a screen designer, you can set the limits of the FRO slider there. And if you remove the FRO up and down buttons and DRO for direct entry, the slider will dictate the available range.

What I came up with is edit the FRO down button to just set the feed rate at 80.  So they could hit that and it would go to the minimum, then back up to 90 or 100.  Thanks for the ideas.

Ok So apparently that sets the actual feed rate to 80.  Since most of our toolpaths run at 100ipm, 80% is 80 ipm.  but when I tested it, it just sets the actual feed rate to 80 ipm and is overridden by the next line of code that sets the feed rate.  So apparently that idea doesn't work.  how does the macro pump value work idea work?

Also, I don't use a screenset that has a slider

From the operator menu in Mach choose Edit VB Script option and the editor will open.
If you paste the following into the editor then click file and save and then call it macropump.m1s and make sure it is saved to the macro folder of the profile you are using. Then on General Config page choose Run Macro Pump and then restart Mach, it should now not allow a FRO of less than 80% whether you use the slider, the buttons or type directly into the FRO DRO.

FRO = GetOemDRO(821)

If FRO < 80 Then
SetOemDRO(821,80)
Else
Set FRO = FRO
End If

Thanks a million, this should work!   Just not real familiar with VBscript.
