I have measured at end of the cable previously and got no output there either. However I will try again at the port. I have confirmed by swapping the BOB is good. But I will test at the port.

Thanks.

Will do. Wont be able to get them for a while now as it i just after midnight here. Expect them before this time tomorrow.

I get it. (regarding the txt files)

I have the machine temp hooked up via ethernet so perhaps I can direct post them to the forum.

'Command' needs an actual application (ie linuxcnc) not just a path to an ini file:

try:
Also you might want to change the 'Trigger' to 'on login'

Here you go: There's a 14 and 15.1" version available. I got the 14", and it goes by the very distinctive name of "Jhcztrk Touchscreen Portable Monitor 14 Inch Smaller Work PC Monitor with HDMI USB C, IPS Screen HDR, 400cd/m² FHD 1080P 99% sRGB".

Amazon Link

Google search led to the method shown below, however it does not work for me.
I'm using auto login if that matters.

Suggestions?
 
 

Remove the BOB, measure at the parallel port.
Or use the tester and a piece of wire inserted in the pin 10 or 11 or 12 or 13 and ground/metal case.

If you can use for all your card the following command
sudo lspci -vvnn > lspci.txt
sudo dmesg | grep parport > dmesg.txt
sudo ls /proc/ioports > ioports.txt

And as much it is a PITA copy the unedited txt files to a USB drive and attach them to your next post . Screenshots are difficult to work with.

Have you looked at your input signals from the button inputs with halscope? It is entirely possible that the way the signals are processed and transmitted within the device's hardware makes adding debounce filtering of the button inputs unnecessary or redundant. If you find that the signals need to be debounced you will probably need to either do it with a hal debounce component or rewrite the whc-whb04b driver to add that feature your self.

If I could ask a small favour, could you provide a link to the item, then I'll put the details of the screen in the big RPi thread for others that may be looking for a touchscreen.

Glad you've had success.

Solved!!!

Why Wine?

just a note I also tried the port tester from here
forum.linuxcnc.org/18-computer/4743-parallel-port-tester

Still no output that I can see.

You could look at how myCNC works:

docs.pv-automation.com/quickstart/mycnc-...ngential-knife-setup
It adds the rotations and retracts automatically without touching the G-code, like how you were thinking.

EdingCNC works the same way:

Tangential knife, you need to program only X.Y coordinates and the tangential knife follows, also in circles and lifts automatically up when needed.

 

Thank you for the guidance!

I got a super cheap 65eur 14" touchscreen off Amazon where the seller stated it is USB HID and it works just perfectly fine first try. Much easier indeed to use standard USB than trying to make drivers work for a dedicated solution. 

Couldn't be happier how it turned out - using the VESA mounts to attach the raspi on the back, and have a desk stand I will mount to the back of the mill stand to hold the screen in place.
