Okay. The only reason why I am buying this is because its relatively cheap and so I am trying to keep cost down. Thanks for the suggestion, but are there any other cheaper alternatives that won't really sacrifice on accuracy or anything? I am pretty sure the spindle speed is independent of the board as it has a speed control setting on it. I am not all that knowledgeable when it comes to CNCs so this is merely an assumption. Could I just use a BoB instead of buying some sort of ESS?
Thank you for all this help (I'd be hopeless with out it!)
