5 Axis Desktop CNC Electronics


A 5 axis desktop CNC control electronics.



Geckodrive G320X servo drive (3/09/2010)

Geckodrive G320X servo controller

One potential servo drive evaluated for use. The Gecko is a very compact drive, with a professionally constructed enclosure.




Whale3 servo drive (5/16/2010)

Whale3 servo controller

5 whale3 servo drives will be used to control the mill.

Whale3 drives were chosen over the Gecko320X due to the advantages of a USB interface for computer controlled tuning, the ability to hold servo position without dithering between encoder counts, higher encoder supply current, and lower cost.


Whale3 servo drive stack (6/25/2010)

Set of 5 whale3servo drives.


Servo drive mounting plate (7/31/2010)

Mounting plate for servo drives.



Servo drive stack (7/31/2010)

Servo drives bolted to mounting plate.



Servo drive stack (7/31/2010)

Servo drive mounting plate bolted to mill and connected to 24V 16.6A switching power supply.



Servo drive control breakout (6/18/2011)

DC-DC converter to supply 12v to the servo drive logic, and parallel to RJ-54 breakout stack.



Smoothstepper motion controller (6/25/2010)

Smoothstepper motion controller

Motion controller is run with Mach3 through a USB port and provides step/dir signals to the whale 3 servo drives.
