Trying to start up a 4 axis K2 that was in storage for about 5 years.
It was running when it was stored.

I believe all the Mach 3 settings are correct.
Power comes on, enable works, axis motors are under power.
All four homing switches are seen in diagnostics as well as e-stop.
However, when jogging or homing it thinks it's moving but it isn't.

The laptop that ran it has been replaced with a desktop.
Parallel cable replaced. One cat5 that got pinched was replaced.
Checked power supply and it puts out 24 volts AC.
That goes to a bridge rectifier and comes out as 33VDC which I've been told is correct.
(I only learn EE stuff when I need to)
How that's ok to run a 24vdc motor though escapes me.
What does the USB connection do? I'm guessing 5 volts?

Any help?
