Hi madi,
the four most economical and capable boards are:
https://warp9td.com/ The ESS is the model of choice.
https://www.cncdrive.com/UC300ETH.html The UC300ETH is the model of choice.
https://www.poscope.com/product/pokeys57cnc/ The Ethernet 57CNC is the model of choice.
http://www.pmdx.com/pmdx-424 The 424 is the model of choice.
A rather more expensive unit but very capable, especially if you have old DC servos to deal with is:
http://www.vitalsystem.com/portal/motion/hicon/hicon_integra/hicon_integra.phpAll of these companies support their products and they work as advertised and all have been around for years.
Each of these boards are slightly different from each other, some has this feature but not that one and so on.
Prehaps not surprisingly the Vital Systems Hicon, the most expensive one, has the most developed features including THC, the only one so far to
have it.
Warp9 are trying to catch up, they have just added lathe threading and backlash compensation.
PMDX is the dark horse here, very good lathe threading capability but no Backlash compensation.
The UC300 is a relative newcomer to Mach4 (been doing Mach3 for years) and so has fewer features but a good value board with lots of IO.
The 57CNC has good balance of features, flexible IO with good analogue features.
There are some other differences also....the ESS and the UC300 really require BoBs. I personally favour the simple and cheap BoBs because my
electronics skills allow me to adapt a cheap board to my requirements. If your electronics is not good then more sophisticated BoBs are
probably right for you the MB02 is a good choice for the ESS and a UB1 for the UC300. The PMDX doesn't require a BOB, its built in and has its own
power supply and makes an appealing choice for a no fuss solution.
In truth while they are all subtly different they all work GREAT....any of them will be a much MUCH happier experience than your XHC board.
