Hi,
I think the 3 axis kit is not the best choice. The drivers are the famed....or should that be infamous....TB6600....not the best. The smoke is still contained
in the one pictured but its trying to get out, and it will. The motion control board is ****e.....variously called a RnR motion board, if you don't believe me
have a look on the Mach3 Forum and see how many people struggle with them. The steppers look OK but there is no inductance specification,
you absolutely MUST get low inductance steppers (1mH-2mH for 23 size steppers) or your machine ill be as slow as a wet week.
While buying a kit is appealing, and the price is right, the kit supplier is relying on you not knowing about the ****e components he is selling you.
My suggestion would be to buy individual components, it will be more expensive and time consuming but they will work properly whereas the
kit you propose will work poorly at best.
