I think you misunderstand, I'm not expecting the parallel port and mach3 configuration to be industrial strength because it obviously isn't. Conveniently though using a breakout board and parallel port provides a very quick and cheap means of testing the bare bones of a machine build and thats all I'd use it for.

I'm just looking for a good stable solution to a motion control system on my machine. The thing that has really put me off mach3 is the MPG feature, which is what i really want to work well, I've tested it with a pokeys board, which claimed to offer the feature, but the results were terrible. I've read about other people having serious issues with the MPG feature in mach3 too. No matter how much I ask about the functionality of mach3 with and MPG, nobody seems to be forthcoming with information, why is that? Because it doesn't work? Artsoft have said as much, thats why part of their selling point for mach 4 is "Higher quality manual pulse generator (MPG) = very smooth jogging and positioning without lag time.".

I was wondering if the MPG feature worked well with the ESS or CSlabs?
