Serial Ports only???

[ShellbackBill]

Am I confused? Misinformed?
Reading old threads?

Are serial ports the only interface PC to CNC Controller?

Seems Like rather old technology.

There are also USB interfaced controllers, although these are serial.
There are motion cards which sit in a PC slot which handle the operation of the CNC functions with PID control directly back to the card.
Systems such as Kmotion etc use the PC mainly as a HMI and communicate with the PC via a USB port and handle the trajectory planning and servo control on an out board system.

I guess I was just finding a lot of old posts.

I checked the info on the China Special I ordered, it mentions USB port. So I guess I'm OK.

Very Noob, here. Still bouncing around from topic to topic, because I know nothing.

Thanks!

It depends on the controller but if youve got USB sounds like youll be fine
