Step 1: HOW TO MAKE AN CNC ROUTER AT HOME
Hello everyone, in this review i want to show how i made my first cnc router at home. The most parts i have bought from the local diy store. The tools used to make the router are very simple and are finded in every home. So i have used: hammer, screwdriver, plier, saw, tape line, drill machine, vise and wrench.
Step 2: LIST OF THE PARTS USED
3x nema 23 steppermotor (i have used 1,2 N)
1x arduino uno board
1x A4988 driver cnc shield expansion board v3 (i have used cables)
3x A4988 driver module
3x mechanical end stop
1x pc fan
1x power source (i have used my pc 12v power source)
1x mini mill machine
1x usb a/b cable
github free universal g-code sender
12x m5 screw for nema 23 motors
3x m8 threaded rods
3x m8 long nuts to make the anti backlash nuts
8 mm pneumatic hose to make the couplers
6x slide drawers to make the linear guides
corner brakets to join the plywood and motors
Step 3: THE TABLE
For the table i have used 600x300x18 wood plate.
Step 4: THE PORTAL
For the portal i have used 600x200x18 wood plate.
Step 5: JOIN THE PORTAL
To join the wood plates i have used corner brakets.
Step 6: LINEAR GUIDES
As linear guides i have used slide drawers.
Step 7: THE Z AXIS
This is the z axis.
Step 8: THE X AXIS
Mounting the z axis on the x axis, first i have glued and after i have screwed.
Step 9: THE Y AXIS
After i have fixed the x-z axis on the portal i have mounted the portal on y table.
Step 10: THE ANTI BACKLASH NUT
This is how i made the anti backlash nut.
Step 11: ANTI BACKLASH NUT, THE M8 SCREW AND COUPLER
This is how i made. The anti backlash nuts it is made from a long m8 nut , the screw it is made from a m8 threaded rods and the coupler it is made from an 8 mm pneumatic hose.
Step 12: THE SCREW AND NUT MOUNTED ON Z AXIS
Step 13: NEMA 23 MOTOR MOUNTED ON THE Z AXIS
Step 14: MAKING THE ELECTRONICS
I do not have used the cnc shield v3 (but it is more eazy with shield), and i connected the a4988 drivers module with wires to the arduino uno board.
Step 15: COOLING FAN
To cool the a4988 drivers module i have used a 12v , 80 mm fan.
To power the electronics i have used my 12v pc power source.
Step 16: THE SOFTWARE
To control the machine i have used GRBL GITHUB UNIVERSAL G CODE SENDER.
Step 17: MINI MILL
I have mounted a 170w minimill machine.
Step 18: TESTING ON WOOD PLATE
Here i make a test on the wood plate.
Step 19: SETTING AND TESTING THE CNC ROUTER
So it was very easy to made the cnc at my home with very poor materials and the result it is very good especially for beginners. I hope you enjoy reading this review and start to make your one cnc router.
