The purpose of this section is to discuss motor controls for the DIY Drones CNC project.
There are really only two options - purchase ready-to-go controls or DIY/kit controls.
A major player in online motor control information is CNC Zone. They have had open source and commercials control discussions for years. It is a priceless resource.
The DIY Drones CNC project is a budget bound project. As such the emphasis will be on price.
If when a mechanical assembly (the steel/metal parts) is made, the drive system for the motors can be the owner's choice if price is not an object.
All electronics are subject to obsolescence. What is hot, popular, and fast today may be cold, common, and slow tomorrow or next week.
My gainful employment and hobby has been in the electronics world for over 35 years. It continues to change and amazes me constantly at the power we now have at our finger tips.
With only one CNC project under my belt, I am no expert. On the other hand, the 2nd CNC project is always in the back of my mind.

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. ;)
