Retrofitting a TOS FNG 32 NC

I wrote
"kev@debian:~$ halrun -U
Note: Using POSIX realtime"

but I have the same result. I also restarted my computer.

I attached custom.hal also 

I dont know why, but your custom.hal file looks suspiciously like my main hal file.

delete everything in your custom.hal file. it sholdnt contain anything at this point...

Yes you are right. I deleted it and now my program starts!

I don't really know how it turned out like that. I thought I had erased everything and started from schratch. Oops.

Today I connected my EXE 602 box. I set the value to 200 inside Pncconf and it works. If I manually move Y 10mm I can see it in AXIS that the machine has moved 10mm. When I try to jog Y I will get "joint 1 following error" and no movement.

I only have one EXE box connected yet and that is to the Y axis. At one time I tried to jog X witch was a mistake because the whole milling table ran away and hit the side before I could switch it off, It was a surprise to me.

I have also plugged in the spindel drive. I have not tested it yet because it is powered by a contactor, I want to draw this contactor from my relay board that is controlled by my Mesa board. Is this done with ladder programing? I believe I want to switch it on a couple of seconds after the machine has been powered up.

Edit:
I found the "Servo tuning detailed how to" by tommylight that I will read now 

Today I plugged in all of the EXE boxes. 
I tried to enable the machine but LinuxCNC doesn't let me. I can see that one of the axis is slowly moving, like 1mm every 10 seconds. I also get "Joint error" immediately on the same axis. 
What could be the cause of this? Is it some ground issue perhaps.

Your servos are drifting, and you need to adjust the center point either on your drives, if they have that feature, or within LCNC. Adjusting the center point on the drives is the preferred method, as if for some reason your drive inhibit output fails, or you don't have a drive inhibit connected at all, you servos will stay in place.

Now that you have things hooked up you get to experience the joys of tuning. There are many articles around this forum to get you going on this. One of the first things you'll want to do when you start tuning is to increase the following error limits - I recommend something around 2-3 inches.
