Well, this is my first post (about my first cnc), so hello.
Am wanting a cnc to make pcbs, and came across this one:
http://www.amazon.co.uk/gp/product/B...A2D0WLNIN2PEPT
It seems to have slightly better build quality than some of the other generic 3020's.
As have understood, the autolevelling can be achieved by connecting leads to the spindle and pcb surface, the result is fed back to a parallel port pin.
Have not seen mentioned exactly which PP pin should be used - I assume there are parallel port connections not used by the cnc controller and can choose any of those.
Just wanted to check this is doable - I doubt it's possible to make a quality pcb without the autolevelling - and the cnc will not be any use to me if it cannot do the pcbs.
The only other slight worry is using a PCI card for the parallel port - am thinking about this one:

Thanks...
