Cyclone (Circuit Cloner) is a design for a CNC mill intended for PCB manufacturing

Here's a Great Looking Open Source Project. That could really Transform your PCB Diy Work...

To-Do list

  • Hardware:
    • Reinforce left&right frames
    • Reinforce screw holders in the Z axis parts
    • Add Endstop holder files (same of Prusa/Mendel)
    • Create holder for a vacuum cleaner
  • Software:
    • Export Z probing results to a standarized file
    • Create a graphical user interface
    • Fix bug in that doesn't mind the depth of the cuts, this affects only when cutting the edges with >1 passes
  • Firmware:
    • Keep motors always on, in order to do homing only once each milling session
  • Misc:
    • Create assembly instructions



  • Note: The linear bearings of the X carriage must be glued in place (use epoxy or similar) since vibrations produced by the spindle motor move the bearings out of place.
  • v0.9.7 has an improved Z carriage: uses much less plastic, it holds the spindle tightly and leaves more metal surface exposed for better cooling.
  • v0.9.6b has a robust Y axis motor stand (improvement suggested and tested by Yopero), and the Z carriage now shows the name of the machine (how cool is that? :P)



  • No news, it is Marlin with support for G30 probing command

Interesting links & Misc. ideas


Bill of materials
TODO: Add general hardware, motors and electronics to the list.


  • Using a thick wood piece as the main base.
  • As shown in one of the pictures, a cheap dremel-like drill has nice bearings and is a good option as the main tool. Finally it will be using a proper spindle (check the BOM for the reference).
  • Desired working range of >=100mm for the X axis and >=160mm for the Y axis.
  • Parts are designed to be printable with the small volume of a Printrbot Jr
  • Bed leveling will be done with probing and an appropriate software.

Software: existing work

The origin of Cyclone took place while I was inside the Panda CNC community ( This is from December 2012 to mid-February 2013.

All other development present on Cyclone has nothing to do with Panda and is not related to the Panda project.
