"Vivid" CNC Router

Overview

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

Specifications

TODO:

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

Software

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

TODO: determine steps per inch for Z axis leadscrew

Axis Microsteps per revolution Motor Gear Teeth Driven Gear Teeth Pinion Teeth Pinion/Ballscrew Lead Steps per inch
X 2000 20 60 20 5/32" 1920
Y 2000 20 60 20 5/32" 1920
Z 2000

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

Controller

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.
