Martin, I'm guessing that the original plan for your wooden CNC was delivered in pieces that had to be assembled like a jigsaw puzzle? And I'm thinking that the plan-assembly-stage is where things went wrong with your machine.

The good news is that once you have re-assembled the plan correctly, you should find that most of the machine parts are reusable..... Alternatively you may just find another use for the symmetrical geometry of your current machine!

Hope This Helps.
