My first experience of the power of CNC and stepper motors was watching my Z-axis a quite happily plunge a 1" square of aluminum and the pen which was inserted in the end of it thru 2 x 18mm MDF boards making a perfectly formed square just as if I'd used my mortising machine.!! . . . I'll never forget the look on my son's face when we looked at each other with eyes wide open...:smiley_simmons:


Now get it working and the first thing to do is the Aztec calendar it's a perfect test of the machine. Then next thing is to make something nice for the Mrs and surprise her, get her on side and you've cracked it, she'll never hassle you again...:hysterical:

Thanks Dean and thanks Clive! Can you email me the Aztec model? I’d love to give it a go once I’ve skimmed off the bed

Nice Joe. Did you skim the bed first. MDF is not the best HDF would be better

Yes skimmed the bed. At that scale with my cheap Chinese cutter I’m pretty happy with how it turned out in mdf. I’ll try it with hdf or ali...

Sorry, Joe, it slipped my mind but I see you got it. Try cutting it in something harder like Acrylic, HDPE or Ali it will come out a lot nice than on that nasty MDF at this size. MDF is ok when it's larger but not when it gets small as it can't hold the detail.

Well done - if only more Build logs had a payoff like this. Congratulations on a successful build, and thanks for sharing so much here and on Youtube. Your reflections on the journey and lessons learned will be of great interest. Best wishes

Andrew, they do it's just it doesn't always get shown. One of the reasons you don't see so many machines builds finished isn't because they don't get finished, well should say used because they kind of don't get finished. Often it's because soon as they get to the point the machine moves they start using it to make things and that's the last time they do anything to the machine until it breaks or gives trouble.
