I build CNC machines 24x24 table alone $999.00 and up depending on the size. 24x24 complete system with Mach3 and Turbo Cad $2250.00 with stepper motors, power supply, stepper driver. The only thing you should supply is a computer. These machines are made from t slot aluminum and are rated for .002 or more.

I would imagine pictures would help and pictures in detaled area's rails, ballscrews etc.

Yer would like to see PICs etc..

Trade you a broke laser for one.

I found this on craigslist. I did a google with the email " sootyjosh@hotmail.com "

The "Martini's plaque" thats posted in the craigslist link, is posted here on the zone by another user (spoiledbrat), I remember it from a few days back (very cool work).

I cannot claim the Martini poster as my own work that is just an example of the capability of workmanship. That did turn out nicely though.

Unsupported rails and small at that?

So was that cut on one of your machines? If not isn't it a bit deceiving that you're advertising it in that way? It just seems to me that you may be misrepresenting your machines a little bit. And if they are as good as you make them to be, why do you have to resort to selling on ebay and craigslist and spamming here? And as joe pointed out how can some of those longer length machines hold up with such flex in those unsupported rails? :confused: Best of luck.

Well i ran all the calculations on this table and the deflection is only 0.02 in 17 ft of rail just for the t slot alone. The lineal rail has a a deflection of 0.07 in 15 ft of rail whiich means that I will only get about a 0.00018 deflection in a 24" piece table unsupported. but instead of being unsupported I have the Linear guide and the T-slot togethor so I can literally run a 17' table with almost no deflection supported or not. But since the table will be on a table it wont matter. How is that for being unsupported?

I have read a few entries about how the unsupported rail thing and the question about the accuracy of the machine I am selling. Let me add this to my last post. The linear guid post have an accuracy rating of .0001 with a weight capacity of 320 kg which is about 800lbs static load weight on a 1"x1" block, which I am guessing is about a 550 lb linear motion capacity. Which means that with two linear blocks with a 800lb static load capacity each side you could almost cut a car on this machine. Any Questions?

What are you using that will only deflect .02 in 17ft? Seems like you're a bit off on your calculations if not fully supported.

:confused: Some things just don't add up, that's all. And could you please clarify on those photos? Where those cut on your machine, or one of your machines? Have any photos of actual stuff cut on your machine instead? We aren't trying to beat apart your machine, just trying to clarify some details regarding it's fundamental specs. :)

No offense taken I like to act smarter than I am
lol
The pics on the ads are not of my particular machine. The design and specs of this actually call for greater accuracy but I can only tout conservative numbers I do have to oppolagize for one of my calculations I said the deflection of a 17 ft table is .02 it is actually .217 and 2 inches at the very tip end of a 17 ft piece with no support. But the accuracy of the linear rail has been figured at .0001 so i can safely say I can get within .002
Thank you for your questions I like em
Josh

hey bp092
i have checked out one of the cnc machines
from sooty and they are very similar to the other mentioned
i dont think hes spamming for what ever your talking about and i havent seen any of his on ebay so to clear things up for sooty i think someone needs to chesk there info before making a post or even ask sooty for info.
the main frame is of extruded aluminum and the flex is only .007 or similar at
24inch so if the machine is only 24" and has multiple corner and center braces you can run a 2hp router against thick material and your flex is very very limited.the rail soppurt is from what i have seen is my thought running this on the deflection calculator with a 50lb load.

Can you provide actual pictures of what I would be getting and some samples of stuff cut with it?

Sure I can I am actually making another machine this weekend and will give you all the pics you need.
Thank You
Josh

the 50lbs is just dead weight, you should take into consideration the cutting and motor forces which will apply.

The frame may be extruded alumn, which has nothing to do with the rails which are unsuported, and he has not given the material or size of those so you can not calc. the flex yet.

We are just asking for specs. to be provided. if someone is going to shell out money for it thay may want to know.

Joe

No pictures, no evidence, no real specs. Are you going to provide them?

Not to jump on you sootyjosh but just the fact you posted a picture of someone else’s work giving the impression it was done on your machine would stop me from even considering talking to you about buying it.

HA!!!! This guy thinks unsupported rails will only deflect .070 over 15ft. LOL!! The rail must be 6" in diameter!!!

That is so cool! Someone else likes my work!

new pics now in gallery

No you can't. The linear rail is accurate to 0.001 when mounted on a 0.5 ton block of solid granite.
Not when mounted on something that flexes 2" over 17ft length.

Hi - just a newbie here. I would be interested in seeing a pic / update of your mill when you have a chance to post it. I am interesting in a 24 x 24 size with at least 16 in of Z travel for hobby machining of Al 7075 alloy.

Thanks
