Yes it was miss named but it was meant to stop all motion. Only a thread pass 
would finish. Which you could certainly argue was wrong too.

Yikes!  I can see arguments both ways, but feed hold or feed inhibit 
seems like it should stop all motion, even from manual command.  I guess 
you could have a situation where a clamp or whatever obscures the IR 
link, and if these inhibits prevented manually moving the axes then you 
are kind of stuck.  In my case, I can just turn the probe controller off 
and clear the hold/inhibit.


Yes, a separate jog-inhibit pin would be one way to make everybody happy.

Jon

I agree, up till recently my jog dials were/are ignored when gcode is 
running. It would be quite a disaster if, while it was busy running some 
gcode and a tool laying in the chip tray caught and spun either dial and 
the machine responded to the dial's motion.  If this is now a 
possibility, it needs fixed. IIRC, my fix from wayback is to gate the 
probe signal off unless motion's mode=5 but that doesn't sound like the 
same problem as this one.

Looking at the docs, there is an option that needs to be
set, so I tried connecting the feed hold to
motion.feed-inhibit.  That made no difference it still
allowed jog keys to move the axes when motion.feed-inhibit
was true!

This seems like a real bug!

[Emc-developers] feed hold ?

[Jon Elson]

I was demoing my touch probe yesterday and saw something 
odd. This probe uses IR signals, and so the interface will 
detect loss of IR communication and cause a feed hold.  I 
was astonished to see that the keyboard jog keys allowed me 
to move the axes while feed hold was true!  The probe 
interface sends that status to motion.feed-hold, and I have 
a tally LED in PyVCP to show the status.  I'm using LinuxCNC 
2.8.2


Can anyone duplicate this?

Thanks,

Jon
