Hi All
Hobbycnc.com website has two kinds of driver boards :
1- HobbyCNC PRO chopper driver board (4 axis) (99$)
2- 4AUPC Chopper driver board (59$) (4 axis)

I want to purchase one but I don't know which one I need for a foam cnc cutting machine (4 axis) , I don't know why is this difference in price though both of them are 4 axis driver .

please , if anyone has an idea , tell me
thx a lot

The PRO board appears to have a more recent driver chip. I believe it has better protection circuitry. The 4AUPC looks like it is being discontinued. You could ask on the Yahoo group.

I have the PRO board and am quite happy with it. I would spring the extra $40 for the PRO board just because it is more likely to have replacement drivers in the future.
