This is a CNC machine made of the remaining parts made by my school robot.
The only thing we pay for is the circuit board.
About $70 in total.
This is done without direction and all is tried and wrong.
This should get you started if you want to build one. 1.
I started with the aluminum base (19. 25 wide, 13. 5 deep and . 25 thick). 2.
There are two columns installed on it (10. 25\"). 3.
The middle is a brace (16. 25\")4.
There are also two pieces mounted on the base 1.
Install the \"aluminum angle\" of two 24 \"fully extended drawer sliders for the y-axis \". 5.
We used Accuglide rails and sliders on the x and z axes. 6.
For X, slide rails are mounted on a piece of aluminum (3 x 19. 25 x . 5)7.
The x-axis is mounted on two columns.
The way we do it is adjustable so we can make adjustments for our dremel trip. 8.
Next, I made the z-axis slide.
It is another piece of aluminum with sliding rails installed. 9.
We did some 1 \"x.
5 \"aluminum block for Z axis gasket. 10.
These are put on and it is installed on the slide on the x-axis. 1.
Next, I made some mounting brackets for the motor.
With these things, it\'s like being hit.
You may need to do something before you get all the permissions you need.
I made it with 1/8 aluminum.
X is just a flat piece, and Y and Z are 1/8 aluminum bent at 90 degrees. 12.
X is mounted to the same piece of aluminum that The X slide rail is mounted.
This way, the motor moves up and down with it if it needs to be adjusted. 13.
The y-axis is centered between the two drawer sliders and screwed to the end of the seat. 14.
Z is installed on the Z axis.
You may need a gasket to get the right gap distance. 15.
Next, I cut about 1/4 of the rebar near the length I needed.
At one end I put a bearing on the rod.
We got the bearings from some old video recorders.
The video head of the VCR has two bearings, perfect for the rod. 16.
You need to install a bearing at the end of each shaft. 17.
Next, I made some steel brackets that weld the hook nut, and when the motor turns, it moves the different axes.
Again, it\'s a blow and you need to measure the size of your machine. 18.
You can start installing them once the production is complete.
I start with the x-axis.
I connect the bracket thread to the X bar and connect it to the motor with some of the plastic pipes we have.
The pipe actually works fine.
It is attached to the rod and closely fits on the motor shaft. 9.
The other end of the x-axis is fixed in the appropriate position by the bracket mounted on the column, and the bearing is fixed in that position by some self-tapping screws. 20.
You need to screw the x-axis connector Holder onto the z-axis so it can move back and forth.
You need to drill holes, maybe you can drill with a counter so you have gaps and check to make sure the screws don\'t get in the way of the x-axis bar. 21.
Z rebar is fixed on the motor with the same pipe as X.
Screw the Z connector bracket onto the Z screw bar and install it on the motor.
The bearing is fixed in place again with several screws.
The bracket will be screwed to the slide with the tool holder. 22.
The same is true for the y axis under the desktop.
The bearing is fixed with some self-tapping screws. 23.
There is only a 3/4 piece of medium-fiber board plywood on the table.
Here are the MDF with two corners screwed to the edge.
Then twist the slides of the two drawers to the top.
Once the table is ready, slide in and make sure it slides back and forth.
Next, twist the Y coupler bracket to the back edge of the table.
And twist the bearing in place. 24.
You should install the motor and all the brackets.
The next step is to connect the wires. 25.
We used 3 axis TB6560 CNC drive step Board Controller 2. 5A.
We bought it on ebay. 26.
These instructions tell you what color of the wire the PIN number of the parallel port is. 27.
We draw things using AutoCAD and AutoCAD inventor.
Then we generated G-using Visual Mill and Lazy Cam-CODE.
The visual Mill is free and works well. 28.
Mach 3 for loading G-
Put the code into the machine and run it.
Mach 3 is free, but you can only run so many lines of code. 29.
You need to calibrate the machine.
Each step is different depending on the degree of your motor and the thread size and quantity on the bar.
I took a screenshot of all the settings I used in Mach 3. 30.
You can add limit switches and home switches if you want.
I would recommend an email
Just in case, the stop button on the machine. 31.
After calibration, you can draw something, save it in the correct file format, and load it into g-
Code and toolpath generator.
This is a visual factory or lazy Cam for me. 32.
These programs will generate G-Code. It will be a . tap or . nc file. 33. Load the G-
Put the code into Mach 3 first, and then run dry.
After you\'re sure it\'s ready, try to test it out. 34.
Wear safety glasses! ! !
The bit does break. 35.
You will get it after a bit of trial and error.
There is a photo of a scorpion illuminated with a red LED for CNC! ! !
