Error at startup

Seems to be an error message that pops up when secure boot is enabled.

See:
forum.linuxcnc.org/9-installing-linuxcnc...i-o-privileges-error

Here is a post by dewey (confirming the issue of secure boot and parallel port):

According to this the issue was supposedly fixed a while ago.

Thank you Aciera, so that begs the question, why error on parallel port if it is not used in any way shape or form?
Then again, secure boot and all it's f#ck ups!

I tried, i really did, back when there where evidence of developing UEFI, i screamed my lungs out in the HardOCP and 2CPU forums to stop that.
I failed. It was (and still is, even worse now) a testament to humans not standing up when they should.
Sorry for the rant.

so that begs the question, why error on parallel port if it is not used in any way shape or form?

That is a good question. I guess the 'fix' was to not abort the startup and add the hint about secure boot to the message.

Not even you can protect us from these kins of perils, but thanks for trying anyway

Thank you all for the quick response.

The issue was that I assigned the wrong limit switch pin to the wrong joint number. I am using mesa CT to build my configuration I have version 2.1.4 I believe its the latest version. Now I have the motor synced successfully, when I click home, both motors shaft turn simultaneously but my limit switches are not responding when I click them. MESA 7i95T seems like a good card, but unfortunately, it doesn't have wiring schematics that I can refer to. Can someone guide me on how to connect limit switches the right way on Mesa 7i95T?

thank you   

For the isolated inputs, assuming sourcing limit switches:

Limit switch common =  --> +24V that is, the common pin of all limit switches

Limit switch NC pins --> 7I95T inputs  (IN8,IN9, IN10,IN11 etc)

All input common pins used for limit switch inputs --> 24V COMMON  (INCOM8,9 INCOM10,11)

(I skipped inputs 0,1,2,3,4,5,6,7 in case you want to use them for MPG inputs)
