You would need the original control program to run that machine through the serial port. It sounds like a "smart" controller ie a controller that handles the motion calculations. This type of controller requires usually a proprietary program to control it.

EMC only works with dumb drives ie drives that take step and direction or velocity/torque with position feedback as the motion calculations are done in EMC.

Does the machine have DC servos? Do you have a photo of the machine and drives?

On the second look, it seems this router use stepper motor.

2.3 Motor
X, Y, W axes are digitally loop-controlled for speed and position via optical encoder
sounds like a servo

Well, it definitely works . Just ran engraving sample from HP-DL format and router did it just fine(XP based PC). Yet what i really want to know is what kind of motor it has and will i be able to run it from EMC.

Pop the cover off the Z and take a close up photo. There are some steppers with encoder feedback but not usually. If the axis feels like it has cogs when you turn it by hand it might be a stepper, if it feels smooth when you turn it by hand then it is a servo. If it is a servo and has brushes (plastic screw caps around one end) it is a DC servo AFAIK.

Knowing your drives and motors work is a huge plus.
