Greetings.  My apologies if this subject has already been discussed.  We currently own an EZ-Router CNC table, and we use Mach3 to control it.  I'm wanting to start future-proofing this control system.  Does anyone know if an EZ-Router CNC table can be controlled using Mach4?  We're not using the parallel port for control.

Thanks in advance!

Hi,
yes, Mach4 can do as you require.

When all said and done Mach3 is a Gcode interpreter and a trajectory planner.
Mach4 is a Gcode interpreter and a trajectory planner.

Where Mach4 differs is the manner in which the program is constructed, its highly modular. It has a highly editable GUI. It is vastly better equipped to
be customised to a certain machine with a much more robust scripting environment. It has a PLC which is many times faster than Mach3, and it has
a PMC module equivalent to 'Brains' in Mach3, but can operate across different sections of Mach4 unlike Brains in Mach3.

Don't get me wrong Mach4 is a steep learning curve.

Mach4 all but requires an external motion controller. There are six different manufacturers of motion controllers that are Mach4 ready. Iuse and recommend an
Ethernet SmoothStepper ($195) by Warp9TD, but there are others, both cheaper and more expensive.
