Re: My next controller
What do you actually want?
Mach3 is the controller in your old machine.
Mach3 would have been doing software pulse (step) generation (unless you have a smoothstepper)
The Tb6... Board is a breakout board and stepper drivers.
These days most people use some form of hardware step generator. Software step generation is limited in speed and there are problems with computer latency.
There are some systems where the software and hardware cards are a set / complete system (one brand software and hardware).
And others where you have a range of options for hardware step generation for one software controller.
