==Goals of CNC training==

CNC is all about processing gcode. The process is -
#Design
#Convert
#Cut

Design Options
*Inkscape
*TinkerCAD
*Sketchup
*AutoCAD
*Other CAD software

Convert
*gcodetools
*CAMBAM
*???

Cut
*Mach3
*LinuxCNC

Using Mach3
*Pin/Port, motor, and GCODE configuration
*Jogging the machine
*Setting the home point
*Testing the cuts
*Changing the bits
*Dust collection
*Changing the speed
*Rewind/Reset
*The STOP button and limit switches

Preparing the machine
*NEVER move the motors manually while connected to control box - it can damage the electronics.
*Zero the spindle high above
*Test the gcode
*Zero the spindle for real
*Monitor the cut, adjusting speed as needed.

Preparing the workpiece
*double sided tape
*screws (and sanding smooth)
*clamps and dog holes?
*vacuum table would be cool
*dust control
*Leveling the table to the gantry

Common problems
*Run out
*Bad gcode
*Bad cuts - too fast, too dull, too deep
*wrong units (mm vs inches)
*wrong arc method (absolute vs relative)
*stuck limit switch
*cheap control box (prone to break or overheat?)
*watch out for obstructions (this also means screw and clamps)
