I've made a little progress on the new machine. I estimate I'm about 80% complete. I'm going to donate the 1mX1m Shapeoko2 to our local Maker Space.

Nice work, but be aware that the remaining 20% will take 80% of the time.

i keep wondering, if you're going through that much trouble, why not build it in aluminium?

Price is the main thing, and rigidity another. I don't see an advantage in using expensive aluminum extrusions that won't give me any more rigidity (and could possibly be less rigid). My cousin is getting a water jet and if I can make the thing out of aluminum sheet...that would be something! But right now MDF will accomplish what I need it to do and very inexpensively.

Make sure you seal the MDF. Stability across a wide range of temperatures and humidity levels is why Aluminum or steel win.

Another note, you probably need to pot your fasteners in some way. Over time, the vibration of machining will cause the wood screws or whatever attachment hardware you are using to back out. My modified Shapeoko 2 has mostly lock nuts in place for this reason.

I understand what you're saying about screws backing out. Once I seated each woodscrew, I backed the screw out then wicked in some super glue to permanently harden the threads. Then when it was dry I put the screw back in. It was rock solid at that point.

Have made some progress. Hopefully the Youtube vids below will work...

The first is the rolling chassis. I'm not all that happy with the table I built, but it works for now. I'm going to learn how to weld and build a steel table.


The second is the X working with the stepper. I'm using the Arduino-gShield combo to test it. I'll have discreet M542T drivers for the actual setup.

Good stuff!

Fixed the videos for you. Rather than the shortened URL [­youtube]https://youtu.be/...[­/youtube], use the full URL [­youtube]https://www.youtube.com/watch?v=...[­/youtube].

Just a short vid of my new DIY machine drawing a 2X2 inch circle/square (which was a perfect circle and square...whew!). I'm working on getting the electronics in the enclosure then I'll cut my first part.
