Limit and Home Switch Choice

Eddy don't do that has when you "Feedhold" you won't want the spindle to stop spinning. It could still be in the material which would cause tool damage.
Also When you release "Feedhold" Mach won't start the Spindle without an M3 command or OEM code to turn it back on and if you "Feedhold" chances are your in the middle of a job and just want to pause for something like clearing chips etc. . . That's the point of "Feedhold" it's not to be used for Emergency or any Safety feature.

I never suggested using it for Emergency or safety use. Regarding leaving spindle turning, I can make it do that, thanks.

Feedhold is not for this purpose and shouldn't be used has such IMO. In Mach's case it also doesn't stop instantly either has it has to clear the Look-ahead buffer first so can't be relied upon to stop quickly.

I'm only using FeedHold from a pause pushbutton and the spindle overtemp so that I can carry on again after assessing the situation, I saw it carries on a while depending on the look-ahead setting. All of these features are easily 'shorted out' in the panel if they become a problem later on.
