In all honesty they are have there good points and bad there is no wrong way to do it, it's all down to budget I have seen someone to a retrofit with a low end industrial control and it's nice unit  and that's what I would use but some people want to use a pc for there hobby work to have there cad system on the same pc etc  and have abit of a play if your serious about making production parts maybe not the best machine but with a industrial control a very cheep production machine in a small foot print, 

Can we please drop this? 

And maybe  create a new thread for acorn controls ? Save the confusion of users of the group
