CNC mill stepper motor controller


Hi y'all from France!
I've been aching to get my hands on a CNC machine from quite some time now, unfortunately I'm quite a noob when it comes to electronics and such.
I'd found that while the machine itself is not that hard to build (see all the ables), however the electronics involved are just too complicated for me to build a controller from scratch.

I've found the other day some seller on french ebay selling a complete controller without the power supply, so I've been wondering about it but am not in the position to fully understand that piece of equipment.

So my question is: what do you think about it guys? Does it seems to be ok (BTW I've also found 3 NEMA23 stepper motors, precisely the same model as described in the specifications for the controller board on its seller's page)?
For now I just want a three axis CNC machine capable of cutting polymer foam and soft wood, so I don't really need expensive and powerful stepper motors.

Thx for any kind of input!
