Error at startup

Hello There, 

I am building my config file, but I'm having trouble when launching my Linuxcnc file. what I am trying to do is sync joints 1 &2 as a single Y-Axis I have configured limit switches on inputs 1 and 2 for each motor joint can someone point me in the right direction I'm not sure what wrong I'm doing here. I will post my INI and HAL files here as well. 

I appreciate any help you can provide. 


Here's my error message at startup

I will give it a try and see how that will go

thank you

There does not seem to be any parallel port reference in the hal files.

Maybe the generic "cannot gain I/O privileges" message includes
the parallel port warning.

This "cannot gain I/O privileges" message does suggest a build
problem with the LinuxCNC version he is using.

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
