So i bought a new standerd 10am SS Relay to turn my spindle on and off. And I changed to shielded cable for going from my BOB and my relay. This seemed to fix my issue of the spindle turning on and off. Or so i thought. I was running a long operation the other day. It was like a hour of cut time or something. So i get it started and then go and start on programing my next peice. and i can hear the router in the backround. and i hear the spindle turn off. then turn back on. So i go out and look and it aint anywhere close to being done. So i though hey im hearing things. then it does that about 2 more times and i go and pause the program. And unhook the relay and wire the spindle direct without the relay and from there it works fine. I am at a loss.
When wired direct it runs fine. I put a amp meter on it when it was running at max rpm and it was only pulling 5amps. But it was not cutting anything. I am unsure if it pulls anymore when it is running or not. I am thinking it something with my computer sending a siginal to my BOB to turn the spindle off. Also when i turn my computer off my spindle turns on with the relay. Is this normal? i couldnt find any way to change this.
Also i tried installing a diffrent parrellel port. A Pci parrellel port. Here is the link to it:

I tried changing the address for port1 or port2 and i cant ever get it to change to the right address. when i get to work in the morning i can check the address of the new port.
