I need some help trying to debug a hardware issue. It would be great if someone could come over and help me.
Here is what is going on:
computer > interface box > control box > cnc (steppers/sensors/etc)
The machine chirps about every second. It seems the power supply is resetting itself or something. When I unplug the cable to the computer, this noise goes away.
When the lights in the interface box come on (pin lights) (PMDX card), the CNC will move for a brief moment (x,y,z) as those signals seem to go live. It's a very disconcerting noise too.
With the computer unplugged, when I wave a wrench in front of the sensors, the lights flash in the control box card and I'm pretty certain in the interface box as well.
Anyway, all is not well here. I need help. I'm losing money by the second.
