Emcoturn 120 lathe retrofit

I have the file modified. but I cant figure why I am not getting 2 lights on the mesa card. The 24v power one is lit but the logic power one is not. I am only applying 24vdc (+) at pins 1,2,3&4 and (-) at pin 8 of TB1. I have the W1 junper in the left position which I thought would also power the logic but I am not getting the logic power light.

I think I am also still using the wrong version of linuxcnc. I have an rtai build and an rt build. All the work I have done so far I think is in the rtai version. I think I will have to remove the rtai version but its going to take a couple setup files withit. Since I no longer have internet connection restoring those will make me backtrack to get the internet working again....

looks like logic power comes from tb3. I will jump this and see if it is the problem.

I added the connection for 24vdc on the TB3 connector and the logic power light is now lit. With the computer on it flashes the 4 green user LEDs in sequence and I can ping the mesa card now. So that looks OK. as far as the linux install. I have two choices at startup. The rtai seems to work for linuxcnc, but it may be a configuration issue. When I start in the "rt" version it will not run linuxcnc. any thoughts? I don't start in recovery mode but I have to move the cursor or it automatically chooses the first configuration. I just wanted to get the picture.

ok thanx. So it seems now would be a good time to hang the usb network adapter onto this box so I can do the updates. What would my /etc/network/interfaces file look like to add the additional network? I commented out everything in that file except the manual ip settings because it was trying to connect to the old network when I booted.

another option would be to download the required files to a usb to update the rt version. is this possible?

Im going to try the net first. Im guessing I just need to uncomment the original lines in my /etc/network/interfaces file and replace the eth0 with eth1 for those lines.

got the net by commenting out all of the new lines and uncommenting the old lines in the /etc/network/interfaces file. I guess my network adapter doesn't work with linux. I get this

user@linuxcnc:~$ ls /sys/class/net
eth0 lo

I think I should see usb0 which would be that adapter.

I did get all of the preempt rt steps completed. now I guess I need to load the hm2_eth?
