Quick conversion

October 25, 2010

So, I had a big DC linear power-supply that I picked up whilst I was in the states, but the problem was, it was built for 110volts (not 240volts like here in Australia). A bit of thinking later, and I popped the Toroidal Transformer out of its enclosure, and discovered its model.

Thankfully it was simply a matter of re-wiring the input so that it is in series, not in parallel, and I have a HUGE 40v power supply to use for the CNC machine. Sweet.

New towers for v2

October 5, 2010

So, worked on the machine tonight. The new towers have been built for a little while, but they were not bolted to anything. Now, the bearings have been attached, and the whole lot has been bolted to the Y axis.

I created new towers because the old ones were ever so slightly out of shape. The old machine had created them, and the racking caused them to be slightly off. Oh well. I remade the new ones by hand. They turned out pretty damn accurate.
