Haha, you are in luck that someone bothered to print information on that thing.
I would
- provided nothing damaged on the machine, not touch its electrics.
- get it running without integrating the spindle into the control. (safe that machine configuration)
- start working on spindle integration with another machine configuration (that way you can take your time to figure it out and still use the machine to cut something)
Did you do your latency test? Keep in mind: Should you have to replace the PC, a PCI or PCIe parallelport card is a means to provide a parallelport for cheap. No need to hunt down a PC with onboard parallel port.
Chances are that you can drive the VFD via PWM directly. (maybe a digital potentiometer is an easy way to do) A 2nd parallel port can be added if there is not enough IO left for the VFD.
