Spindle CCW button shows up - despite not connected

I'm setting up LinuxCNC 2.7.8 to run my CNC mill.

AXIS documentation suggests that the UI buttons should auto-configure; and indeed I don't have spindle brake items displayed. Despite only defining 'spindle on' using stepconf (I also tried using spindle forward as an alternative), I'm getting a 'spindle ccw' button displayed.

I've checked the HAL files carefully and can't see any pins connected that would explain this behaviour. Is this a known issue, or am I missing something basic in my setup?

Any hints appreciated. Go easy though, I have very limited knowledge of Linux.

Yep - that's what I understood.

My problem is that there isn't a net command anywhere I can find that includes either spindle direction, so I can't see why the CCW button is available (my mill only runs in one direction, there is no reverse facility).

I mentioned that brake isn't showing (and isn't required) to indicate that I understand about how this is supposed to work - sorry if I ended up confusing what my question was about.

Does the auto-configure for axis happen every time Linuxcnc is launched - or could there be something hanging over from when I connected spindle CW to the parport rather than spindle ON ?

Thanks - the documentation says

The Spindle group
The buttons on the first row select the direction for the spindle to rotate: Counterclockwise, Stopped, Clockwise. Counterclockwise will only show up if the pin motion.spindle-reverse is in the HAL file (it can be net trick-axis motion.spindle-reverse ).

So either the auto-config doesn't do what the documentation says - or I have something in my HAL files that I'm not seeing. Main HAL file was created by Stepconf wizard and I can't fund any mention of the reverse pin in it (manually or using Find).

Thanks - so the good news is that I didn't mess up the configuration. I'll double check that the unwanted button doesn't actually do anything when I get the PC connected to the mill.

Looks like this used to work 'as advertised' - the PC is replacing an underpowered one which could only cope with EMC 2.3 - just checked today before swapping PCs, that old one only showed the spindle CW button. I'll have to put a post-it on the screen to hide the CCW button....
