A full day working on the control box and 90+ degrees in the shop.

I now have all the major bits mounted to the back panel and have about 1/3 of the panel wiring complete. Tomorrow is a new day. Hopefully its cooler!

Top left is a small 120mm fan and radiator. Just below is a 12V pump. Both are the cooling system for the Spindle. Top right is 4 servo motor controllers and the main board mounted on a homemade bracket on top. Middle right is Hitachi 2.2kW VFD which will control the speed of the spindle ~7kHz - 24kHz. It will be powered by 3 phase 208V. Middle left is a small relay mounted on a black heatsink and various wiring connections. The relay will be used for the estop circuit.

Bottom there are 4 48V 7.2A power supplies that will power the servo drives. They are arranged in parallel and have a 0.1 ohm resistor and schottky diode on the outputs of each supply. This is to ensure the power supplies don't fight with each other. The far bottom left power supply is a 12V output supply that will power all the low power stuff like the pump and fans, etc.

The interlock will jumper out AC to the 4 48V power supplies as well as the main board and VFD interlock circuits. The 12V supply will be turned on and off by a rotory on/off switch on the outside of the panel.

Lots more work finished in the last couple of weeks.

The goal now is to flip the switch on the beast by the end of the weekend. I'm finished up the control box electronics and getting all the bits wired up. Fingers crossed the LinuxCNC setup doesn't take too many hours.

I'll be posting pics every few hours this weekend.

I've been building a very heavy duty CNC router for the past 3 years. If interested in learning more about the build progress you need to check out my build threads on http://www.cnczone.com/forums/cnc_wo...l_monster.html or on my Facebook page https://www.facebook.com/Canuck.Engineer

It's been literally a monster of a project. I started with a full 3D CAD model of my design in Rhino which took several months to draw. Next was procuring all the raw materials, parts, tools, etc. that I would need to build it. Finally I also joined the Club Workshop in Denver and took their CNC machining classes so I could use the CNC knee mills to make some of the parts. The actual machine build started in Aug. 2011 and has continued to this day.

Along the way I learned much about machining and metal work and the original design evolved as I picked up new CNC machine skills.

I finished the mechanics in May of 2013 which is almost 1 year more than my original plan. Now I'm working on the wiring and plumbing.

As far as budget I'm 50% over my original plan but I've upgraded some stuff as well. The budget was for materials, software, computer, and parts. It didn't include the thousands of hours I've put into this.

The machine is designed to cut Aluminum, tooling board, wood, foam, etc. It's should do all of it with ease. I hope to be knocking out my first wing mold project as soon as I finish the build.
