Well, I think I figured out the problem... I un-plugged my wireless network adapter and ran my test program with the spindle running, and no false triggers!
I am using a D-link USB 802.11G wireless adapter that sits right in between my PC and my electrical control box.
It just came to me one minute that 802.11 uses RF to transmit and receive data, and one type of interference that I've heard of is RFI, so maybe it's related?
I still should rewire my system to provide proper grounding and swap out all my cables for shielded ones, but as of my little test last night, I might be good to go. Hopefully I won't be back on this thread in a week saying the problem came back.
I'm not in the forums as much as all of you guys who replied to me, so keep this in mind if someone else has a similar problem to mine.
Thanks for all the help. |
