=1 Categorization Key=
#redirect [[CNC Machine]]
 
*The numbers left of each category refer to category strength, low-high being strong-weak. For example, 1 is stronger than 2.
 
*Stronger categories cover all weaker categories below it until a stronger or equally strong category is established. Examine the following.
 
1 Tools
 
2 Drill Bits
 
1 Materials
 
2 Bolts
 
2 Nuts
 
*The category Drill Bits is contained within Tools; the categories Bolts and Nuts are contained within Materials. Note that neither Materials nor Bolts nor Nuts are a part of Tools; Nuts is not a part of Bolts.

*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
