Ever since I bought this router, I have had problems with it. First, the Y axis ballscrew was broken at the threads for the front screw. After waiting a month for a replacement ballscrew, (Should have returned it at this stage) I found it had trouble maintaining Z axis height. It would cut fine for a bit, then it starts dropping in the Z axis on each pass, while the Mach3 screen showed it was maintaining Z height. I was working on it the other day, when it stopped moving in the X direction for about 2 seconds. When it started moving again, it had no idea where it was and cut right through the side of the model and banged into the stop. Does this sound like a ballscrew is hanging up, or maybe the stepper motors? I changed the Z axis driver board and the red eagle board and no change. At this point I just want it running. Would I be able to just buy a kit on Amazon or Ebay with the motors, controller and BOB and make this thing work?
Thanks for any help
