On day 5 I got all of the limit switches mounted to the machine.  I spent some time trying to figure out where and how I wanted to mount the switches.  I also needed to find an easy way to actuate them when the machine reaches a limit.  I scrounged around in my junk parts bin and came up with some pretty neat methods on how to actuate the switches at each limit.  The main requirements of my chosen scheme is to make it look neat and keep it functional.  Go here to read about the ongoing build and take a look at some pictures along the way.

Day 4 of the build is now in the bag.  Updates on the V90 status slowed down a bit as I had to wait for the limit switches to arrive.  I got the limit switch assemblies completed minus mounting them to the machine.  Go here to read about the ongoing build and take a look at some pictures along the way.

Day 3 of the build went somewhat quicker than day 2.  I got the machine fully assembled and operational (minus adjustments).  Go here to read about the ongoing build and take a look at some pictures along the way.

Day 2 of the build is a wrap.  I got more accomplished today than I thought I would be able to do.  I managed to unwrap and inspect the remainder of the parts in addition to assembling the gantry and the base.  Go here to read about the ongoing build and take a look at some pictures along the way.

So, my FireBall V90 CNC machine arrived on 30 May 2012.  The posts that follow will document the build and my user experience.  Day 1 started with me opening and inspecting the components.  Go here to read about the ongoing build and take a look at some pictures along the way.

Today I managed to gather enough nerve to purchase a FireBall V90 CNC machine with all the bells and whistles from Probotix for under $2000.  The V90 has the following features:

• Approximately 12″ x 18″
• Thomson precision linear shafts
• Oilite bearings
• Precision Acme 2-start lead screws
• Anti-backlash drive nuts
• CNC USB controller and software
• Aluminum T-slot extrusion spoil board
• Bosh Colt PR20EVSK Router and holder
• MeshCam software
• 3-Axis ProboStep Motor/Driver Kit
• 40 VDC Linear RTR power supply
• Larger enclosure for power supply and motor controllers
• 220 in/min rapids

The machine is supported by the  FireBall CNC Yahoo Group.
