Is it the DDCS V3.1 ? I was looking hard at their DDCS "Expert" for an upcoming project - $425 CAD on Amazon. Only a few bucks more, has a few more buttons.
I currently run Linuxcnc + Mesa 7i76E card on both a mill and lathe, but I'm just too lazy to relearn all the config stuff again. Also, I'd be spending $270 US plus duty on a MESA card, ($219 + $50 shipping), need a PC and display, etc. The standalone seems like a good idea for a small simple 3 to 4 axis machine.
I have the ddcs 4.1, I paid 317$ on Ali, I don't have and mpg wheel or anything like that
