Hello
I have been looking to buy something a long time, but haven't decided yet.
I think that 4 axis would be a good idea. That I wouldn't need to upgrade whole system if i want to go from 3 axis to 4 axis.
I have been looking these packages:
Probotix - Seems to be okay and full kit
4-Axis SideStep CNC Stepper Motor Driver Kit -
Hobbycnc - Soldering is not an issue, but is it good :S
HobbyCNC PRO Driver Board Packages | HobbyCNC
TB6560 - Looking these threads with problems I think these are not good.
4 Axis TB6560 Driver+NEMA23 Stepper Motor 1.3Nm CNC Kit | eBay
Linistepper - have seen some good things about it
PIC Linear Stepper Motor Controller
I don't know witch one to choose? Maybe you more experineced guys can help.
