I have been on the site for a couple of years now reading and admiring others. I built a 4x4 plasma table for a small rackmount shelf business. The business was doing so well, I took the profits and started a new router build. I just thought others would be interested in an eventual 5 axis solution addition to the KRMx02. All of you have inspired me....I want to give back.

I researched and researched and came to the conclusion that a cncrouterparts or Kronos kit would suit my needs. I was really hard deciding between the kits, but I eventually went with the KRMx02.

I purchased two doughty drives for a B/C head, but will start off with only using one them for rotary since my software is Aspire. I work for a large company in Redmond Washington where I will be able to get a fair deal on 5 axis control software when the time comes.

Why am I building this?
I do not want to get into the products I have in CAD right now, but lets say I am tired of CNC jobs going to China. I maybe naive, but instead of complaining about it, I want to eventually be part of the solution instead of being part of the problem. I love seeing people like Ahren from cncrouterparts and Micheal from Kronos devote their lives to offering products to help us accomplish our dreams.

I will try to update when I have one of the doughty drives installed. I should have started the thread earlier, but I think people have seen the KRMx02 build. I wanted this to be about the rotary and B/C addon.

Looks good, would be very interested to see how the DoughtyDrive system works out. I think the black paint looks a bit easier on the eyes than the red in the renderings...

thanks...yeah...That is kind of the reason I want to take the drives in baby steps. Rotary first, then B/C after that. I am getting tired of watching one video of the doughty drives cutting into material. It is time for someone to just shoot forward and use it in everyday application. I trust the drives, but I am so curious how far I can push them. Some of this is a learning experience also. I would rather screw this up then some 100K machine.

Had some stainless steel laying around and cut out a quick track holder guide with the cnc plasma. I really like how cncrouterparts made theirs so I kind of copied :P

Cut out an adapter to allow a 6" chuck to fit the doughty drive's bolt pattern.

Colin Doughty was very helpful with Mach3 settings. The rotary is mounted and calibrated.

I have never seen the KRMx02 look so good. Nice work.

Is the spindle up and running?

When this picture was taken it wasn't running, but it is now. I am only cutting foam right now. I just raised the gantry because I needed to raise the 4th axis up. This gives me 4 more inches on my stock/material.

I think I got the foam idea from you actually. I am taking home depot foam and gluing them together with guerrilla glue. It works really well and gives me any size block I need. Ordering large chunks of foam is such a rip off so I feel this is the easiest way since the foam is going to be coated with smooth-on D65 anyways.

Some of the guys building the KRMx02 Use longer supports to raise the gantry. They then increase the Z-beam/rail/ACME screw by the same amount. This gives them an incredible Z range.

Yeah I thought about that, but with a 50x102, it seemed harder and more time consuming for me. Raising the supports on a large table after its already put together seemed intellectually easy, but physically more challenging. I about broke my back just placing the current supports on there

Subscribed, Nice build. Thanks for sharing. I'm starting to build a KRMx02 50x27. Its great to see how each person adds their own touch to their machine. Nice pictures and info of your machine.

thanks!

Good luck with your build...its a lot of fun.

Decided to use cheap home depot insulation foam for testing rotary 3D toolpaths. Glued 2inch thick foam together using guerrilla glue (not the wood guerilla glue)

Just wanted to give an update on what my machine has been doing....

Finished up a 11th century medieval table and still working on the iron man statue.

[msimpson99]

It's good to see some of the finished products coming off your machine. Keep up the good work.

[Op4]

thanks man.....it has taken awhile to learn the best techniques. Things are getting better.

[msimpson99]

I know what you mean. I am working on some new books on building milling machines and learning about many metal working techniques. Many of which will make their way back to the KRMx02.

that is awesome. great work.
