	Small CNC machine, ~~good~~ for [[PCB Milling]].		== Safety ==
			[[File:Cnc e-stop.jpg\|thumb\|200x200px\|Emergency stop\|none]]* Emergency stop (E-stop) cuts power to motors, should be released only when milling is in progress
			* Debris and broken tool parts my go flying from the spindle. Wear eye protection when E-stop is released!

			== Operation ==

			=== Milling machine ===
			[[File:Cnc mill.jpg\|thumb\|200x200px\|Milling machine\|right]]Small three axis CNC machine, controlled by PC with LinuxCNC.

			Good for [[PCB Milling]]!

			=== Motor driver and spindle controller ===
			[[File:Cnc driver.jpg\|thumb\|200x200px\|Motor drivers, spindle control\|right]]Normally set to be controlled by PC, but provides manual spindle control.

	== ~~Safety~~ ==		Also contains the emergency stop.

			=== LinuxCNC controller ===
			[[File:Cnc linuxcnc.jpg\|thumb\|200x200px\|LinuxCNC controller\|right]]PC running LinuxCNC atop RTAI kernel. Provides manual movement control and runs GCode programs.

			=== Spindle cooling ===
			[[File:Cnc cooling pump.jpg\|thumb\|200x200px\|Spindle cooling pump\|right]]Water needs to flow when spindle is running. Turned on/off via extension plug along with mill and controllers.

	* Emergency stop (E-stop) cuts power to ~~motors, should~~ be ~~released only when~~ milling ~~is in progress~~		=== Tools, bits, drills ===
	* Debris and ~~broken tool parts my go flying from~~ the ~~spindle~~. ~~Wear eye protection when E-stop is released!~~		[[File:Cnc tool box.jpg\|thumb\|200x200px\|Tool box\|right]]There's a box with a lot of various tools. Few are going to be useful for PCB milling: a sharp cutting tool, a 0.6 mm or 0.8 mm drill and the 3.175 mm sideways drill.

	~~== Parameters~~ and ~~Operation ==~~		Use 13 mm and 17 mm wrenches to unscrew the tool holder and replace the tool.

	* Three axes		=== Workpiece probing ===
	* Controlled by PC with LinuxCNC		[[File:Cnc probe.jpg\|thumb\|200x200px\|Probe attachment\|right]]Probe triggers when there's a conductive path from it to tool/chasis ground. To use it, the workpiece needs to be isolated from tool/chasis ground and have the proble clamped to it.
	* Water cooled spindle

	== ~~Useful GCodes~~ ==		== Tips & Tricks ==

			=== GCode simulation/preview ===
			You can verify if everything is correct by importing all files to [https://camotics.org/ Camotics] G-code simulator.

			Ideally your board should start at positive X, Y coordinates with lower left corner near X0/Y0.

			=== Useful GCodes ===
	* '''G0 X0 Y0 F100''' -- Non-cutting move to X0 Y0 at 100mm/min, Z coordinate stays		* '''G0 X0 Y0 F100''' -- Non-cutting move to X0 Y0 at 100mm/min, Z coordinate stays
	* '''G38.2 Z-5 F30''' -- Move Z up to -5mm at 30mm/min (slowly) until probe trips		* '''G38.2 Z-5 F30''' -- Move Z up to -5mm at 30mm/min (slowly) until probe trips
