30 Second timeout before opening and E-Stop button not clicking...

Trying to setup Probe Basic Lathe for use with an EMCO Compact 5 CNC lathe with my own electronics.
After the splash screen there is about a 30 second delay before the main GUI appears.
All looks okay, the tabs work but the E-Stop won't click...
Note: In AXIS the E-Stop is correctly asserted for the 7i96s, and the power button works to enable a 7i96s output.
I think it is a python thing, but don't know where to look.

$ qtpyvcp -i

The last error message (whilst I was sorting out the copying of stuff into the .ini file - not getting any at present) had this:

Traceback File "/usr/lib/python3/dist-packages/qtpyvcp/plugins/notifications.py", in timerEvent error = self.error_channel.poll() ^^^^^^^^^^^^^^^^^^^^^^^^^ linuxcnc.error: Error buffer invalid

... not sure if any relevance.

How about the SIM, does the SIM start and work as expected? If so it's almost certainly a config setting issue.

This sounds like maybe an estop conflict. Or perhaps a post gui hal file issue.

Probe in Sim works okay... now comparing the various files.
Thanks for the suggestion.

Find the culprit?

No, sadly not!
I tried various other things too, but nope.
I am going back to do a completely new install from scratch of Linux, etc. which requires a SSD shuffle between computers.
...

if the sim opens and works (ie.. press estop, press power, press ref all and it works) its not an installation issue. the problem would be pointing to your machine (milling machine) configuration problem, maybe post your configuration to github and share the link here so we can have a look and maybe help get you sorted out. having the configuration on github is nice because you will always have quick access to it for reference or troubleshooting even when not at your machine pc.

Okay, my two setups are here:
github.com/TriodeGirl/LinuxCNC
The AXIS one works, the Probe_Basic is the issue.
I am using a MESA 7i96s board set at 10.10.10.10
I have E-Stop enabled, and am supplying a suitable active signal to the pin input. This works under AXIS.
Many thanks.

first thign i see is you ar emissing the postgui hal file that is required. you need to uncomment the ini for that line and copy over the probe basic post guiio hal file as is stated in the docs.

it looks like you may have missed a few steps, go beack through the machine config section in the docs really carefully and make sure you have done all of the steps accordingly and i think you will find things will work as expected.
