*Information resources required to construct different versions of the CNC Circuit Mill are saved in this section.
 
*Version 1

Notes: Using the same template in a given axis for alignment and shortening the spindle shaft for stability are important. Sleeve bearing mounting method needs improvement. Separation of cubeframe and axes structure ideal. High thermal energy draw from overvolting raises concerns.

=Soldering Stepper Driver Pins=
 
*Insert the short end of the male headers into the stepper driver board from the bottom, then pressfit the headers into the small breadboard for holding.
 
*Apply flux to all header connections
 
*Apply solder to the tip of the soldering iron
 
*Solder header connections at opposite corners of the stepper driver board for stability, reapplying solder to and cleaning the soldering iron tip as necessary; repeat for the remaining header connections.

avr-libc
 
*In Synaptic Package Manager, click "Apply"
 
*Restart your computer
 
=Getting RUBY Programming Language=
 
*Open Terminal and type:
 
sudo apt-get install ruby1.9.1
 
*Restart the computer for the changes to take place
 
=Getting GRBL Files=
 
*Open Terminal and type:
 
git clone https://github.com/damellis/grbl.git grbl
 
=Getting Gctrl=
 
*Open Terminal and type:
 
git clone https://github.com/damellis/gctrl.git gctrl
 
=Getting Processing=
 
*Go to this webpage:
 
http://processing.org/download/
 
*Download the latest version of Processing to a directory of your choosing
 
=Moving RXTX files=
 
*Navigate to the Arduino IDE folder>lib.
 
*Copy RXTXcomm.jar
 
*Navigate to the Processing folder>modes>java>libraries>serial>library
 
*Paste RXTXcomm.jar, replacing the existing version
 
*Navigate to the Arduino IDE folder>lib
 
*Copy librxtxSerial.so
 
*Navigate to the Processing folder>modes>java>libraries>serial>library>Linux32
 
*Paste librxtxSerial.so, replacing the existing version
 
=Modifying Gctrl=
 
*Open the Gctrl folder
 
*Open gctrl.pde in gedit
 
*Change a part of the code as annotated in the following:
 
Serial port = null; //change starts
 
String portname = "/dev/ttyACM0"; // Linux, Arduino Uno
 
//change ends
 
boolean streaming = false;
 
=Modifying GRBL Files=
 
*Navigate to the GRBL folder
 
*Open "Makefile" in gedit
 
*Edit the PROGRAMMER line as:
 
PROGRAMMER = -c stk500v1 -P /dev/ttyACM0 -b 115200
 
=Flashing GRBL=
 
*Open Terminal and navigate to the GRBL folder (ex. by using the "ls" and "cd" commands)
 
*In Terminal, type:
 
make clean
 
make
 
*Connect the Arduino Uno to the computer via USB cable
 
*In Terminal, type:
 
make flash

=Modifying GRBL Settings=
 
*Navigate to the Arduino IDE folder
 
*Double-click "Arduino" then click "run" in the popup window
 
*Note: you may want to create a quick launcher for the Arduino IDE
 
*Connect the Arduino Uno to the computer via USB cable
 
*In Arduino IDE, open Tools>Serial Monitor
 
*Note: the Serial Monitor window should pop up and you should see the following:
 
Grbl 0.6b
 
'$' to dump current settings
 
*In the Serial Monitor, change the left drop-down setting to the following:
 
Both NL & CR
 
*In the Serial Monitor, type the following in the command line:
 
$
 
*Note: you should now see the following:
 
$0 = 157.480 (steps/mm x)
 
$1 = 157.480 (steps/mm y)
 
$2 = 157.480 (steps/mm z)
 
$3 = 10 (microseconds step pulse)
 
$4 = 500.0 (mm/min default feed rate)
 
$5 = 600.0 (mm/min default seek rate)
 
$6 = 0.100 (mm/arc segment)
 
$7 = 0 (step port invert mask. binary = 0)
 
$8 = 25.0 (acceleration in mm/sec^2)
 
$9 = 225.0 (max instant cornering speed change in delta mm/min)
 
'$x=value' to set parameter or just '$' to dump current settings
 
 
*In the Serial Monitor, type commands as necessary in the following format, where "X" and "Y" are numbers:
 
$X = Y
