I been mach3 user since 10 years on my diy cnc converted milling machine, it is very cumbersome to handle windows and its PC hardware that crashes or stops in between runs many times mainly due loose cable or failure in PC components.
I recently bought cnc router 6090 from China and had 3 options to control like ncstudio pci card, mach3 or stand alone dsp like rich auto a11. I selected dsp option and thank God I did that. No longer PC to maintain and each axis runs simultaneously. Just plug in pen drive and run g code. I took a risk and was ready to convert to mach3 in case this dsp didn't work out. But glad it works nice and fast and no issues since a year.
I would recommend standalone cnc controller anytime instead of PC.
