Hello
My name is Andrej. I'm computer programmer and my hobbies include building rc model aircrafts, geocaching, electronics,...
I love flying wings and three years ago I created my first CNC foam cutting machine. At that time I was learning how to program microprocessors. I created controller for my machine which was using RS232 to communicate with computer. Controller accepted dxf for wing root and another for wing tip and send step/dir pulses to stepper drivers.
I used that machine for some time. Main disadvantige was, that creating those dxf files took quite some time and a small change meant that everything has to be done again.
Some months ago, I needed to cut some wings. I found out, that Profili2 supports 4-axis GCode generation. Time to create new controller has come.
GCode parsers, linear, circular and helical interpolators were programmed, USB support was added and CNC USB motion controller was born. Cutting wings with my foam cutter was now easy thanks to great Profili2 / CNC USB motion controller compatibility. Check out video on my foam cutter page.
But why stop here. I had everything ready for true 3+1 axis machine. Except machine itself. A friend of mine Ultralajt created his machine and I decided I'll create mine.
Main design goals were, that everything must be build with simple tools becouse I don't have any special equipment. Machine must be cheap but parts must be upgredable to better quality ones.
I don't have any plans and all my sketches are not publishable. I doubt anybody but me understands them. I'll try to photograph everthing. Feel free to ask any questions.
I can't wait no see full power of my CNC USB motion controller
