I recently purchased A 4x4 APC machine from ez-router , I had nothing but trouble with it ,first all the programming was not with the machine or not correct after 2 weeks finally got someone out to look at the machine and put new programming on it and get it running. Machine still does not operate properly highly dissappointed with machine and service , would not purchase if I could go back in time.Received no operating or trouble shooting manual , so I'm operating blind . Can any one tell me how to set up the size of the part I want to cut ,Thanks.
