scorbot-er-3

I own a Scorbot-ER-3 Robotic Arm. I have LinuxCNC 2.9 running on a HP envy h8-1534. I tried to run the Scorbot example and get this error code:Print file information:

I get the same error when I try to run the config without hardware (I don't have a Scorbot) so I would assume that this error indicates a problem related to communication with the Scorbot hardware. Maybe try running 'dmesg' and see if you can see any related errors in the output.

You will need a real time kernel to run LinuxCNC.

Note: Using POSIX non-realtime
This means you're using a non-realtime kernel.

Indeed, the error does not appear running this on a machine with real time kernel.
Note that you may have to add the user account to the group 'dialout' to be able to access the serial port.

It is also looking for a serial port from Python...

You are correct. I was trying to run a simulation on my HP envy h8-1534 computer to test the software. I am in the process of setting up a Dell Optiplex 980 SFF i5-650 3,2GHz 4GB Ram computer with a parallel port, to run this Scorbot-er-3 robotic arm. I prefer to shake out the software first before attaching to a live machine. I would like to know if anyone else has used (Copyright © 2020) andypugh software for running a Scorbot-er-3 through the parallel part?
