Ctc fdm 3d printer, newbie asking advice

[curious aardvark]

what port speed is it set for ?
Communications baud rate.
Most printers use 115200

But the real dirt cheap ctc i3 pro b - uses 250000 baud rate.
I know, I have one :-)

FDM stands for: Fused Deposition Modelling.
Ie laying plastic down in layers that stick to each other. It's the type of 3d printer NOT a model name :-)
