BOB suitable for 3 axis+ B/C head build?

I'm not that familiar with parallel port/db25 instruction. Can I daisy chain the two boards together or do I need to run a separate card to the second BOB?

Not sure what you mean by this. But to use two PP BOB's you will need to P ports on the pc. so you would need another PP card fitted and the two cables one to each BOB.

I have been using Linuxcnc for these simple jobs but it is a learning curve. I think Mach3 can take at least two PP BOB's then you would set them up in ports & pins. Plenty of vids on the net for that.

Yeh i've just been reading up on the setting up Mach3 with two PP ports. Think its a case of getting lucky if you dont get a driver conflict on the installed PP card however it'll resolve what I want. I have the boards so might as well give it a go :)
