Jd garage plasma table

Is the purpose of the cantilevered gantry to let you slip larger sheets on the table?

I would be concerned about the cutting torch bouncing and shaking with that design. My understanding is the floating gantry arm is supported be 3D printed plastic guide brackets? Hmmm....????

A conventional gantry secured on both sides would make me feel more comfortable.
I don’t think the cantilever will be a problem with its size. It will help with loading for sure. I also was concerned about 3D printed parts. But. The only thing the 3D parts are doing is mounting ldler wheels for travel. The square ng is taking the load.

I also think the gantry can be lighten by moving that axis motor. His design has it on the z axis mount. Where I think you can relocate the motor to the double 2” tubing. Keep the motors stationary.
I’m gonna start collecting materials and do alittle more research.

Also my thoughts. Additionally, could you use some 80/20 extrusions for the cantilever to further lighten it.
Check out the plasma table by @Tmate HERE for an example of using 80/20
 
I did see a guy on utube that used an aluminum piece of 2x2. There was sag I can’t remember if he was the one that basically put a roller on the end of the cantilevered arm. There is framing from the table that the wheel is able to ride on. It eliminated any sag. With the redesign I was thinking of it would put all the motors for the x&y on the main frame. I don’t think I will put a z axis motor on. Fairly easy to set height and run with it.
As for aluminum tubing or 80/20 I don’t think it’s a good environment for it. I have a friend that has had a 5x10 for awhile. His setup uses 80/20 for the beam on the gantry with v groove bearings that ride the groove within the 80/20. With all the metal dust from the plasma getting on the 80/20 the bearings are lapping the grit into the aluminum. No good!
 
Is that a particular software version (possibly with minor updates) usable forever?
Many software providers are moving to a rental plans (yearly or monthly).

Thanks,

They are both a buy version. Not rental that is why I chose them
 
He says he’s using fusion 360 the free version. Idk what he is using to process.
I believe fusion 360 has a processor program built it but not for sure. I use Solidworks for cad stuff.
 
To lower software costs, you could use GRBL and a microcontroller board (Arduino or similar) or LinuxCNC. Fusion360 has a CAM setup that should be able to export code for it.

that is what JDs did they wrote custom Adriano code for the controller and THC.
 
Just came across this thread, I have the langmuir Crossfire about 4-years now. That investment paid for itself in about a month here at my shop.
The original machine ran on Mach3 and I added my own 3rd axis THC. I recently upgraded to Firecontrol and Langmuir's 3rd axis THC and the system is way more user friendly and I have had no glitches whatsoever. Holes in 16g sheet are down to 1/8" diameter and overall accuracy is in the order of 0.010".
Langmuir and PrimeWeld's aftermarket support is second to none.
I CAD in AutoCAD 2007 and CAM in SheetCam. Plasma Cutter is PrimeWeld CUT60. Shop compressor is Campbell Hausfeld 60gal 5HP and it ran for 20-years (3-month oil changes) in the shop before blowing the pump, which I recently changed-out.
I've cut up to 1/2" sheet on it with no issues, but most of my work is below 1/4" (mounts, brackets and such, and lots of 16g electrical/electronic panels etc.)
My water table management (flood, level, drain. filter and top-up) is my own design and build and fully automated.
I really like the JD Garage offering of a Tubing Notcher attachment, but I have no need for one in this shop.
Here are a couple clips of my crossfire in action:

That looks great. I've had my eye on the Crossfire for awhile now.
 
I actually bought the plans. Have not gotten around to building it. I am considering the idea of going with an arcdroid simply to have a smaller footprint unit that I can stow aware when not in use.
