New in Somerset UK

Hi All.
Gone from manual milling (with calliper2pc and DRO's) to small Sherline CNC 5400
Mainly been using 3D printers (latest Ultimaker 2) for a while but want to get back to a machine that "takes away" rather than just "adds"
Having a few teething problems that I am trying to work through but slowly getting there.
The controller for the Sherline has a "routeout" card and 3 as yet unidentified axis cards.
Will no doubt be back when I get completely stuck and screaming for help but for now I am living on google search and youtube.
