Hi everybody.
I'm totally new to the CNC scene, but have decidede that i want to build a 3 axis CNC milling machine. I have got a friend of mine who works with automation in his daily work to help med building the mechanics, but i dont have e clue as where to start with Software etc. I'm a electronics technician my self af have been giving som ethougt to making all the electronics my self. My plan was to go with a PIC-USB µcontroller. But my problem is that i dont know what data it has to be able to interprete to motion.
So my rather comprehensive line of questions are:
- What PC based freeware "CNC" applikations are good? need to be able to create routing from CAD drawing.
- What kind og data does the applikation actually send to the electronics in the router and how much data does it send?
- What type of motors shall i be using? sevo/stepper?
- Anybody got schematics for at motorcontroller i can build my self, or is it advisable to buy a controller?
- Is it possible to get a complete "blueprint" for at router capable milling in aluminum, for free og cheap somewhere?
I am in the process of gathering materials, aluminum profiles for framing and ballbearing spindels for linear motion(from an old SMT machine)
I have been trying to search through the forum, but since i dont have the knowledge about what to search for, i haven't had a lot og luck... hope someone on this super forum is able to guide me in the right direction...
