To me, this is the sort of thing that makes LinuxCNC more persuasive - the unforeseen features and functions a dedicated controller may lack. You'll have to learn how to set up either option, so better the one which leads to more options?

I like how they advertise the microcontroller:

"32-bit high performance low power industrial grade microprocessor, 400MHz CPU speed"

That's a $10 part:

... but still appropriate. The issue is more that you're presumably locked into only whatever the existing firmware can do. If their customer service is good though it might be a good system.
