      Please contact me DIRECTLY at 719 244 2249 cell. I am having problem with downloading software to run the Mark 2 - 9 axis cnc board. The link on webpage is non-functional and Open Builds Part Store is non-responsive.
      So your help will be greatly desired.
      Thank you for your attention.

      Hi Sonny,
      I am wanting to build a CNC Hotwire, using four V-Slot Linear Actuator bundles. Two of these will be fixed to the table base. The other two will attach to these and rise vertically. But never having actually seen this hardware myself, I am struggling to understand how to attach the vertical LA's to the two horisontal ones. Can you help?

        Sorry. I'm not that familiar with OpenBuilds hardware either, as I don't work for them. I've only seen a few items in person. So I don't know the specifics of how things are suppose to go together. I'm here as support for Grbl (CNC controller), where I'm the lead developer.
