freeze gui on limit switch (hal extern estop) was created by bkt
I add some new row in my custom hal file and in my hal file (charge pump and estern estop) .... in attach you see the modified row ... all works properly but when accidentally my robot press some limit switch the axis gui + pyvcp panel freeze and it is impossible turn off linuxcnc. It is necessary to turn off the pc.
What am I doing wrong??

Are you saying the whole computer freezes?
This should not happen, however you configured linuxcnc.
Can you give more detail?

How about if you try a sample config rather then the one you modified? still hang?
can you run linuxcnc from a terminal and see if there are any clues given.
can you open another terminal (when AXIS freezes) and type 'dmesg' to see if there is a clue.

I have seen this behaviour on my lathe setup using Gmoccapy and mesa hardware. In my case it would seem that Lcnc / GUI becomes unresponsive for a minute or more but then it recovers again. This only seem happens when I use the emergency stop during an automatic or MDI cycle.
On this machine I use the latest production release.

I have similar problem too.
I'm setting up a gantry table, with touch screen monitor.
The power transformer, PC, Mesa 5i25-7i76, all electronics & electricals are housed in a touch screen kiosk similar to a small ATM.
At first, the transformers was powered via a magnetic contactor linked to the Estop and latching ON/OFF via AC signal. when I cut the power to the power trans, 2 things or combination of 2 may happen, 1) screen freezes 2) touchscreen went bonkers.
then I suspected magnetic contactor is a bad idea for a 600VA power tranny , I swap in a SSR and salvage the existing switches and use a DC relay latching circuit for the SSR control which has a nice zero-crossing control, it improved but after more extensively, the problem remains, just less frequent.

KenC: Its likely your problem is not related to the other GUI freezes as it seems to be EMI
related. Any time you switch inductive loads you need some kind of transient suppressor
to avoid generating EMI. For a 600 VA transformer a properly sized MOV device across the
transformer is a good solution.
There (was?) a bug at least in master where specific operations cause a axis GUI hang for about 30 seconds
This was discussed on the linuxcnc-devel IRC channel a month or two ago, but I cant see to find it on
the logs ISTR it was related to MDI

at Marius .... yes is right the problem is only related to MDI command. there are some solution?

Nothing that I know off. I just grind my teeth and wait.
