CNC Machine Progress

Its been quite a while since I added information about my CNC machine, I've made a few videos describing the machine.

First run of the CNC Y axis (gantry):

Here is my first video after getting the three axis together:

First time running with a router:

A bit more progress on the machine

Stepper Wiring

Tek-flex and adhesive lined heat shink tubing; connectors are Molex C-Grid series.

The Wooden Pickle: Linear Bearings & Ball Screw

Something a friend of mine is working on...

The Wooden Pickle: Linear Bearings & Ball Screw: "Slides: 30mm diameter, ~33' length THK Bearings: blocks are 5.5' and 2.75' in length Screw: 15mm diameter, ~22' usable length 20mm/rev. tra..."

I have started a Cnc laser cutter with the hopes of building something good enough to cut SMD solder stencils.

Laser head:
I started with a 300mW IR laser salvaged from a CD burn; later I bought a 1W IR laser off ebay and a glass focussing lend.  I turned a holder for the laser diode; and mounted it it in aluminum heatsink.  I put the whole thing on a CDROM sled mounted on a ink jet printer carriage


Pics and video below.

300mW prototype

1W IR Module cutting wood

For the driver I'm using stepper control modules from Pololu; I have laid out a carrier board for them and sent it off to be fabbed; should be in next week.  Fully optically isolated; two relays for spindle control; 3 inputs for limit switches.  Provides upto 2A of current per stepper coil (up to 35V)
