Again we are back at that discussion... :( 

I am still waiting to send my $50 to Monroe for a prototype!  

Servo for me is the way to go but I have to say that I am loosing faith a bit in seeing this project coming to life in a reasonable time frame.   Yes all fine to want to code it all and get 3DR to do the electronics but is this not adding months to the project?   Can we get a working machine faster and then upgrade it to your latest?

The essential portion of this project is the machine proper - the steel holding, moving, heavy machine that is.

There is really nothing significant to discuss regarding the electronics other than how cheap we can get motor drives made/bought/developed. It seems like we are reinventing wheels.

If we interfaced hamsters to drive the screws then we would be then pondering breeding larger hamsters, best feed for highest output power, should we shave them to help them cool faster after a hard run, etc. ;)

There is a reason good machine tools are not cheap. They are expensive to make. As we have no specifications for the machine (the part that actually cuts stuff), we are sidecar stuck kicking around electronics.

Notice that a couple others that recently joined are asking for specifications. Those values would dictate how much drive power we need to do the work.

It is really very simple.

Again, I am committed to helping and seeing a prototype working.

If someone want to run it with water power, I will help run the belts to the water wheel. ;)
