LinuxCNC start, stop, pause buttons ?

In our shop, we run several CNC mills and lathes. These include Okuma, Tsugami, Fadel, and Daewo. Every one of these machines have prominent green start button and red stop/feed hold buttons, and a reset button that is less prominent

I wonder then, why the decision in LinuxCNC to make the red stup button the stop-and-reset button, instead of just feed hold.

You can just use the Pause button to temporarily pause / feed hold and then resume?

You can make physical buttons any colour you want.

Also, LinuxCNC offers a range of user-interfaces. I think you are describing Axis, which is just one of them:

I have tried Axis but decided to use GMOCCAPY.
I plan to make my physical buttons the colors I described. I am just curious about what led to that UI design in the first place. Does any commercial controller use this design?

The lingering issue is that I now have a big red stop/reset button on the screen, and a big red feed hold/pause physical button.

Or you could do this. Examples are here on the forum



I think physical buttons are much better than the GUI ones

The "Touchy" GUI doesn't give you much choice in the matter. (It _requires_ external run/stop buttons and an MPG)
I see we have the same button supplier (eBay in China

Well actually I got it here oceancontrols.com.au/home.php so probably spent far too much (and they don't seem to sell it anymore)

I think if I did it again, I'd use separate 22mm dia green and say a blue or orange buttons so there is a clear distinction between run/step and estop.

Andy, I have to say when ever I see photos of your lathe, I admire your handiwork.

I set my lathe and router up with a feedhold and cyclestart button. feedhold only pauses program cyclestart will start running of the program and will also resume the program after a program pause. I wanted it to work like my Haas mill.

Here is my hal code snipit for this:

Here is my control panel for a Router.
Red button is stop .
Green start and resume.
Orange lit is pause or feedhold.
