Small CNC machine, good for PCB Milling.

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!

You can verify if everything is correct by importing all files to Camotics G-code simulator.

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

Feel free to upload pictures of your finished PCBs and add link(s) to following gallery:

+== Safety ==
+* 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!
+== Parameters and Operation ==
+* Three axes
+* Controlled by PC with LinuxCNC
+* Water cooled spindle
+== 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
+* '''G38.2 Z-5 F30''' -- Move Z up to -5mm at 30mm/min (slowly) until probe trips
+== Pictures ==
