"Vivid" CNC Router

This equipment requires training. Either it's tricky to use, or it's someone's personal equipment, or it's easy to make expensive mistakes with.

This machine is not presently in service. When it's up and running, a training course will be provided.


Homemade CNC router donated by Vivid Aerial R/C. It is made largely with parts from Avid CNC, the name similarity seems to be a coincidence.

It is driven by LinuxCNC and a Gecko G540. It has a high frequency water cooled spindle that runs off 220V 3-phase (generated by a VFD), and the 220V powering the VFD is from a 110V to 220V step up transformer.

The machine needs repairs!!! Talk to Maverick Edwards or Forest Darling if interested:

  • the water cooled spindle isn't currently able to be water cooled as the inlet/outlet ports are missing
  • the stepper motors (or their cables?) seem to be overheating



  • maximum cutting area
  • maximum feedrate
  • usable spindle RPM range
  • maximum tool shank diameter
  • electrical power requirements
  • overall machine size/weight


The machine is currently set up with LinuxCNC, a powerful (but not always user-friendly) open source alternative to Artsoft Mach3.

TODO: create a table documenting the calculated steps per unit (mm or inch), maximum velocities/acceleration, axis bounds (soft limits), homing speed/direction, etc.

Replacement Parts


Technically the controller is LinuxCNC, but the hardware side of things is a Gecko G540. The G540 typically connects to the parallel port on a PC running LinuxCNC or Mach3 generating step/direction pulse-trains that ultimately drive the stepper motors.

The G540 has on-board stepper motor drives, an analog spindle speed output as well as some relay outputs for forward/reverse, limit switch inputs, and an optional watchdog timer that shuts everything off when communication times out (the controller is configured to generate a square wave on a specific pin to prevent the timeout).

Probably uses ER-16 or ER-11 collets (this needs to be verified).

Both of the water inlet/outlet compression fittings have been broken. The spindle has M8-1.25 threads for them. One was replaced with a spare, but another spare needs to be acquired.

Water Pump

A replacement water pump for the water-cooled spindle has been ordered, it's the same type that the K40 uses:
