G'day Guy's,
Well got the cnc all setup to work and made up a laminated MDF board to sit snug on the machined bed. Had the original 6 holes I had drilled in so tapped them 1/4" BSW and clamped the board down. Next step was to spot drill the board for drilling 5mm holes so wrote a G-code file for it. First run along the X went fine then when moving the Y axis saw the computer go into stall mode and instead of moving 100 mm it only went 74mm and stuffed up the Y axis setting. Kept going and the next Y axis went 100mm too. So now I'm ready to get the cnc going a better computer is needed and my mate up north has an old P4 3gig gaming computer with heaps of ram he is going to donate.
As the 5mm holes are only for clamping the error won't matter and I will have to make a new clamping kit for the cnc. Now some may say tapping MDF won't hold but I did do a test and no way could I rip the bolt out of the test piece. The idea is screw the all thread all the way home then tighten a nut to ensure the stud is firm.
I did know I would have a few teething problems but eh this was madeup from scratch so if nothing went wrong it would always be in the back of the mind WHAT will go wrong.......
