Does this look like a CNC Machine ????

[ger21]

I believe that L is Black, N is White. That's how I wired mine and it worked fine.

oooo hoooooo !!!!

Good news it’s Alive!!!!




I just move it around with the Jog Command in TurboCNC,

I need to clean up all my spaghetti wires before I start getting really into it...


But like I said "It’s Alive"



Thanks every body!!

Hello, Everyone,

Here are some pics of the "finished" Machine,

[flyrc]

Here is a pic of my first part,

I was not sure what happen with the first circle it cut,
until yesterday ..( seem I was missing a G00 )

only thing left to do is add some paint...

[anoel]

Hey!!! you got round holes on your first try. You have no idea how lucky you are to not have to track down where your play or backlash is happening. My first machine took me forever to get round holes.

[flyrc]

Thanks,

Well two out of three is not bad... !

the first one did not come out because the line was missing a G00 command...

I've fixed this now..

I made som delrin Nuts from 1" bar.. ( got almost no backlash)
But the x seems to be developing a bit ( but still to small for me to measure)

Luis,

flyrc,

congradulations. I really like how you stayed focused on your needs and budget and just built what you could aford. Neat machine I hope it does what you want.

If you your X axis turns out to be inadequate you can always add another linear bearing later with a little bit of modification. Same for the standoffs. If you need more rigity, you can make a spacer plate later on.

[flyrc]

So far,

Its proven to work as expected,

No problem with X or .. the stand off yet !
I'm sure if I try to over load it.. wiith bigger job I may see failures.

I was tweeking it yesterday, and cut 50% of the time to run a part.

from 30 min to 15 min.

When traveling at full speed ( not cutting )
i will travel the 35 in X axis in about 8 or so sec..

It was intended as a light duty machine.. ( balsa and ply... ( I will probably only cut 1/8 ply any way.. ) most of my planes are small... have to keep them small to store all of them... (the first one I buld will be one the largest scratch build to date !.. ( 30in fuse and 47in wing ) Normally most if them are in the 30in wing range..

Sorry guys a bit of subject.. ( but this is why I build the machine...so I can build planes )

Well I expect I will be busy working on drawing but.. if any one has any direct question Please feel free to send me a PM,

Later !

[flyrc]

Sorry every one not 8 second.. it take 18 seconds,

It was taking 22 sec to travel 20in..( at 1/8 step)

I change it to 1/4 and moved the top end and accelearation.

and it realy moves now..


I tried several diff PC's ...

I end using a 400MHz box with 64MB and with win 98, ( i boot into dos to run turbocnc )

I tried a few machines that where in the 100MHz range but they just ned not cut it.. (Motor would lock up when ever it reached top speed )

bye !

I notice that you are using a Dremel advantage. I've been using one of those for a while now and I've cut lots of heavy plastic and hardwood, mostly 4/4 oak and 4/4 maple. I've not tried doing anything as heavy as aluminum yet. I dont think that my machine is rigis enough. But then again since you are using real linear bearings youmacine has a big advantage in the heavy cuts that I don't. From the looks of your machine I'd not be too shy, you'd probably be suprised at what it'll cut.

Hi Flyrc,
I have been watching your progress since you posetd "Does this look like a CNC Machine ???? ".

You have come a long way, keep up the good work and have fun.

Ken

[flyrc]

Thanks, Ken

I'm glad I found this site..

I was all over the web looking for good info.. so I could star building.

I just hope the info I posted help someone.

My thinking now is the mechanical.. is the easy part,
Keeping it under budget can be a challenge.

The Software can put you way over budget, depending on what you use.. ( so far I'm using turbocnc )

but I would like to "upgrade" to something that does not do the stop and go method.. ( I think that would shave a lot of time off each tool path)


anoel,

Dont tell me those things I may be tempted to use it on such materials... (all though I can say I can use them on to many planes.. not 4X4 pieces any way )

Well I know metal will be out of the question.. ( you may have missed this but I am running this out of my 2 beadroom apartment )... ( makes me almost go out and want to buy a house so I can build a bigger machine )



Luis,

[Ken_Shea]

Yes, I agree this site has been invaluable to me as well.

I am positive your posts have been helpful as well as encouraging.

Budgets are tough to keep in any endeavor but I would say you did very well and when able a software upgrade will be a welcome addition to your projects. I do not do well differentiating between need and want so I know how easy it is to spend more then is really necessary. I have also learned that it is not always a mistake to upgrade past your first inclinations to purchase whatever.

Luis, I sold a house about 6 months ago and was in the position to Rent or Buy again. After weighing the cost of renting or buying again, buying turned out to be cheaper than renting in all but the lowliest of apartments in my town. So i bought again and my house payments are better than most rent. Plus I'll I'll make money when I sell. So buying a house "may be" a good investment for you if you've no looked to hard... Don't rule it out... a bigger machine might just be the exuse you need...

[flyrc]

Yeah,

Something like a 4X8 Ft.... ( then I can build some 1/4 scale planes..)

Oh yeah I can see it now.. a 15ft wing on a .. ( Speed Bee ! )



I think the next CNC Router I build .. when the time comes.. will realy only have modified X axis..so its locked down

Luis,

[balsaman]

Very nice machine. I see that it's working great! Good luck having any time for airplanes now though, CNC takes too much time and is too fun!

I know I tend to work on things until they are finished... (ie the 4 week construction on my CNC ).. I could have build in less time if I had thing come in quicker. This tends to be a downfall at times…specially if I get two projects going at the same time.

I am now suffering from sleep deprivation.....
"WARNNING DO NOT OPERATE HEAVY MACHINERY or POST TO CNCZONE.com if you have had less than 5 hr sleep on average day"

As you will start to make no sense

Just not enough hours in a day to get it all done!

Luis!

Hello everyone…well I was cutting some parts finally.. and I broke my bits…

I picked them up on eBay.. for 4.95..set of 12 diff sizes… I figure.. I could use them to play around and if they broke not big deal.

I’ve been cutting balsa with them and no problem..
I went to cut some light ply (1/8) and I got about half way done with all the part when it broke.

I was running at 30IPM and 2000 RMP on a Dremel advantage….1/16 bit.

Well – I think it was just the quality of bit I was using…

But,

Was I running to fast..??
Was I running to Slow ??
Or is the bit to small for this material??

I ‘m looking at buying some bits from..

http://www.precisecut.com./products/...btnSearch.y=11

Any suggesting would be great.. (cant afford to break to many.. 10$ bits..)

Thanks guys..

[Ken_Shea]

Flyerc I would be inclined to think the RPM is way to low for a 1/16 bit, along with suspect quality.

Let us know what yopu find out.

Ken

[flyrc]

Sorry,

I was 20,000 RMP.. Left out a Zero.. ( Any recomendation on bits you guys are using would be great !


Thanks,
