"Vivid" CNC Router

Overview

Homemade CNC router donated by "Vivid". 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: populate this table, I believe there are notes in a text file on the LinuxCNC computer

Axis Microsteps per revolution Motor Gear Teeth Pinion/Ballscrew Gear Teeth Pinion/Ballscrew Pitch Steps per mm Steps per inch
X 2000
Y 2000
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).

TODO: determine if all axes use the same type of motor

Spindle

TODO: some sort of 220V 24,000RPM Chinese water-cooled spindle. It probably has an 80mm diameter body and uses ER-16 collets.

The water inlet/outlet compression fittings seem to have been removed or broken off, and will likely have to be replaced before the machine can be used. Please contact Forest Darling for more information on how to repair it.
