Mach4 General Discussion / Re: Feed Rate Override Absolute Value?

Thanks Daz,

I figured that I could use a button with an mdi/gcode to change the feed rate. Is there a way to use a DRO to enter a variable that I can then use in that function?
I'm assuming I can use the 'on modify script' section in a DRO to run the function, but I'm unsure how to pull a number that I enter into it.

Mach4 General Discussion / Feed Rate Override Absolute Value?

« on: December 16, 2016, 10:25:15 AM »

Hey everyone,

I'm fairly new to Mach 4 and am setting up a new system. I'm trying to enter a new feed rate for use with the 'Go To Work Zero' button that is on the default screen. I use this very frequently to move in straight cuts as it is a CNC hotwire machine. I need to frequently change the feed rate depending on what material I'm cutting.

the API indicates that mcCntlSetFRO is only be able to change the feed rate by percentage. Is there a method of changing it to an absolute value? Or is there perhaps a way to use a DRO to enter a new value with the 'f' Gcode command?
