Scary fast G203 cnc router/plasma cutter

[Dan Mauch]

Here is a video of my nearly finished cnc router/plasma cutter.

I have a bit more to do in that I have to build the plasma cutter torch holder and make the clips to hold the metal from the bottom. I need to make the vertical stand parts also.
The idea of my machine was to build a simple cnc router that I could roll around my shop and when not using it store it vertically and out of the way.
I'm using a rack and pinion drive with 2 452 oz in bipolar parallel wired motors driving the Y axis. The right hand motor is slaved to the other motor using Mach3 software. I'm using the Gecko G203 step motor drivers. I just finished routing a new address sign for my house with this machine. I'll soon post a short video of it running.
I live about 1/3 of a mile from the Woodinville McLendon's. God Bless McLendon ! While I built this mostly from parts I already had, it seemed like I was running down to Mclendos every time I worked on the machine to get a fasterner or something. They always had what I needed whether it was metric or imperial.

Is the plan to produce that as a kit or something else?

Just curious.

Maybe!. I want to add a 4th axis and most likely a 5th axis.
There are a few more ideas that I want to incorporate and I want to see what the reaction is to this machine.

Nice machine!!

That's gotta be the most unusual way to mount cable chain.

Great machine. Lots of photos please. I want to build one now.

I wonder if there is a reason to mount it that way???

[wcarrothers1]

He must have just had a lot of extra laying around..hehe

I think if you had them internal (ie end mounted to center of axis) he could have used less.

The way I mounted the cable carrier wasn;t the way that I wanted to mount it but I was sort of forced into it because the loaction where it was planned for has an interferrence with the Y home and limit switch.
I still have some more work to do and I may be able to change the cables carriers to a more tradiotnal method after I add the 4th and 5th axis.
I aslso went with this method because I wanted to see if the calculations and the actual performance of the machine were what I thought they would be. As you might guess, I am very happy.

Very nice.

I had mentioned and several people requested a video of the machine doing something.
The cnc router is no longer scary as I lowered the rapid speed from 1700+ IPM down to 400 IPM. http://video.google.com/videoplay?do...15522721&hl=en
Here is a link to a video of the machine cutting a piece of cedar. I am using a 1/4" V Bit to engrave the street address number. I added a clip art of the Cedar tree before the first nyumber and then traced a image of Mt Rainier onto a piece of paper, Scanned it into the PC. Used a raster to vector program to vectorize it and then pasted that into Bobcad 21 to generate the G code. Mach3 is used as the G code interpreter running on an old laptop.
I probably cut a little to deep and I should have been cutting a bit faster as the first cuts burned the wood a bit. Frorgive me for that as I usually work with metal and I am not well versed in wood butchering

Umm.. It rapids at 1700 IPM but cuts at 50 IPM. And how is that useful?

Ok wait, it says "Plasma" here, didn't see it the first time. I withdraw my criticism, then. Carry on.
