Currently using Geckodrive GREX G100 with Mach3. Works great except for 2 minor issues such as tool change auto-zero and reffing all axes simultaneously.
What I like about GREX G100 is that it has ethernet and 6 axis support already built in. It's too bad it was discontinued.
Are there any Mach3 supported ETHERNET controllers which can support 6 axis right out of the box?
G540 with EthernetSmoothstepper can support 4 axes easily, but if 2 other axes are needed it seems that the only way to do it is to add a separate breakout board.
Perhaps there are some other alternatives....
