Cnc Machine
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.
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

Would you like to reduce the backlash?
It is very Easy , i think :) www.dumpster.com is a link with antiback lash solutions and cheap
Otherway you can DIY with a pieces of HDPE High Density Poly Ethilene ( Polietileno de alta densidade , ex tábua de cortar pão)
In a shop of specialized plastic materials you can take it very very cheap!!

I'm quite curious, what kind of accuracy / precision do you get?
and what depth can it cut?
