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: 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).

Spindle
Spindle markings:
HY GFZ-80-1.5 Ø80x188 220V 1.5Kw 5A 400Hz 24000rpm
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:
