Title: Brain to solve negative SFRO
Post by: progress on November 13, 2014, 03:54:47 AM

Hello,

I've used an encoder connected to a pokeys to change the Feed Override value and a button to reset it to 100%

But now I can set SFRO to 500% and over and set it to negative values like -100%
When it goes in negative feed nothing happens because the mill is still in hold position but it's not much nice to see.

How i can tell at Mach3 that the minumum SFRO is 0%?

May I use a brain to do it or there is a specific setting?

Someone can help me to write a brain? I'm not able to.

FOVR is limited in M3 to:  0.0 to 3.0 (0% to 300%), with 100% being actually what you commanded.
it will NOT take a negative number. Nor will it allow you to go over 300%.
