I installed ethtool and I am still getting command not found 

I did a video recently about this

isolate the last core with isolcpus
Disable coalescing if intel
Use dkms driver if realtek
Set CPU affinity for NIC interrupt to be same as the isolated core

Yes, the network is not setup properly (no fixed IP address)
 

sudo apt install ethtool
-
And the network is not set up properly or not connected???

I get command not found for some reason 

We would need more info about what you want to do and what you already did.

Really nice and very useful debug tool. Thanks for sharing! I think this should be shipped with linuxcnc. What do you think?

Only a little note to the selection behaviour - when I click on several components after each other, and when I hold down on the last one and drag, all the previous clicked components are in the selection and are moved together. I think it would be more intuitive to do that with Ctrl click.

The BASE_PERIOD in the sim config is too low for that spindle speed so the sim_encoder component cannot calculate the speed correctly.
Setting a lower BASE_PERIOD in the gmoccapy.ini increases the possible maximum spindle speed
 

Yes with adding the conditional code from the manual seems to be working just the way I want it to.
Here is what I have in the on_abort.ngc file

I started playing with the on_abort.ngc and it might work. I need to play a little more. At this point it does a little more than I want it to. It will trigger it for F2 (what I want), but also triggers it when exiting a running milling file with the escape key (not what I want) and the machine does not enter machine off.

The machine state I'm dealing with is particular about how it is entered and exited. I can't simply turn it on or off without the machine moving, when the M-code is active, it can be turned off without issue when the machine is not enabled (in machine off). So I only want the on_abort sequence to cancel my M-code state when the machine is aborting to machine off. Aborting to a machine on state, such as when aborting a running g-code file, the M-code state needs to be left alone, and the operator will have to clear it themselves (else the machine will shutdown with following error alarms.)

In the remap instructions I read about making some things conditional. I'm going to try to play with that now.

You can try this in your hal-file:

This reduces the acceleration of the axes when moving with the pendant.

Also ich hab mal geschaut.
Standartmäßig gibt es meistens max 3 Kanal für die typischen ABZ Encoder.
Gegenfrage: was hast du vor, evtl. gibt es eine andere Lösung?

According to the docs, shutdown.ngc only gets run when exiting normally.  Machine-off state does not trigger it, and neither does a PC crash.

I think on-abort.ngc should work without explicitly remapping.  A quick test could confirm:

• Create a test abort.ngc file with something in it to test (i.e. halcmd to set a pin value)
• Add the file to you INI
• Create user M-code (M1xx) which creates some sort of call to the abort.
  • All of my M66 checks in the various tool-change (or similar) sequences have something like:

  • [*]M66 P9 L3 Q2                                        ; Check ATC door open sensor
    O100 if [#5399 LT 0]
          M65 P8                                          ; Turn off ATC door open solenoid
        (abort, ATC door not open)                      ; Abort if the sensor does not activate in 2 seconds
      O100 endif
    [*]

You could make the abort.ngc be the bash script, or you could create another M1xx bash script and use abort.ngc to call that M-code.

Once you've got everything set up, open halshow and add the hal pin you want to twiddle using abort.ngc.  Call the M-code which will abort and see if the hal pin changes state.

The conversion interface parts depend on the signal levels needed.

For RS-422 (going into a line receiver on the drive ) where 3V signals into a load are OK,
any RS422 driver will work (say 26LS31 equivalent for 4 channels/chip)

If you wish to drive optocoupled drive inputs that expect 5V signals, you would need
a driver with 5V outputs. AFAIK the only 4 channel RS-422 drivers that do this are
the ISL32174,ISL34172 and MAX3042 (The MAX parts are expensive)

Another option for 5V signals is to use a combination of ACT driver chips with inverting
and non-inverting  outputs, say a 74ACT540 and a 74ACT541.
