Intro: Cnc Machine
Step 1: Drawing the Machine
I started by creating the design of the machine on SolidWorks.
On the PDF i put all the measurements.
Step 2: Start Construction
After seeing all the measurements, I calculated the amount of iron that I would need to build the machine. It was something like 16 meters of square tube.
So I bought two bars of six meters square tube 20*20*2, one bar of 6 meters square tube 25*25*2 and one bar of 6 meters angle iron 25*25*3.
Then I started cutting and drilling holes in all parts according to the technical drawing.
after that i started welding the parts.
Step 3: Motors and Drivers
i bought on ebay one kit of stepper motors with driver and power supply.
The steppers are Nema 23 Stepper Motor 287oz-in
Step 4: Final Product
Overall, the machine is good, just not fast enough because i use a m8 screw as lead screw.
So the machine only can do 300 mm/m
Step 5: Some Stuff
stuff i made with the machine.
