am a newbie here no matter who you are thankyou any way

The Free plans call for HoldDown Channels and all I can to find is t-slots if it is possible some can give me a link to and product number to hold down channels like the one's JrGo is using

Anyone have the part number or bearing number for: dtl11: Flanged bearing??

Hello all, first router complete using the JGRO spec, next I'd like to build another identical one, but more precise than some of the mis-cuts/drills that I made by hand(lots of coaxing of some holds). Forgive me if my question has already been posted, but is there a way to take the JGRO dxf plans and run them thru the ACE converter to generate the gcode or do I just need to redraw them all in lightwave or a9tech? Thanx
Peter

hi

i was thinking of using some M8 1.25 pitch threaded bar for my project as imperial is difficult to get hold of. has any one tried it and with what results?

Thanks Matt

I haven't looked at them, but if they are 2D you'll probably have to offset the lines 1/2 the tool diameter to get the parts the correct size. You could use A9CAD or any other CAD. Lightwave would not work.

If i build the jgro router, how do i set it up with the computer? also, how do i design and then transfer something to the machine? is this expensive software? any tips?
thanks a lot

There are free and low cost CAD systems available, and any program that can output a DXF file (standard autocad file) can be used. Many, here, use Corel Draw to do some of the more artistic designs.

Now, the CNC software is also easily available, and ranges from free, through low cost, to quite expensive. Check out http://www.dakeng.com and look at TurboCNC. It's a shareware program that is quite highly thought of, here.

Ger21, Why will lightwave not work, it can export dxf files? Has anyone else had any luck on converting JGRO's dxf files to gcode? Just wasn't sure if I was missing a setting in ACE r something..
Thanx

JRGO:

I see from your web site that your second CNC mill has a fixed gantry with bronze bushings sliding on drill stock. Is there an advantage of this design over the first CNC design?

Thanks,

Richard

Read this thread. http://www.cnczone.com/forums/showthread.php?t=9885
I don't exactly remember, but it looks like LW's exporter doesn't export any arcs.

rweatherly,

Not really. I thought it might be easier to set up and cheaper, but it really wasn't. Getting those shafts to glide smoothly was a pain. I was trying to get a more rigid machine. It's a little more rigid, but I still have flexing problems in the uprights and the 3/4" shafts that go accross the rigid gantry should have been made with 1" shafts. I just thought I would try something different.

What is the cutitng area of the standard JGRO?

I built a Y-axis torsion box 10.5"x3"x5'6" using 1/4" plywood, sorry no pics of the construction, not sure it was gonna turn out! but I can post the final painted product, pretty RIGID!

I am looking for a 50"x 26" with at least 6" on Z cutting area (scalable to 50"x50") and wonder what I can scale everything to

Thanks for the link, that helped a ton, hate to have spent a fortune on LW 8 and it fails at something so simple, heh, but I didn't buy it for my mill, just trying it out..Thanx again!!

hello im new to the cnc area and wonderd if ill use different materials such as steel or aluminum will I be able to use a dremel to cut 1 mm of secc steel or 1mm aluminum ??

and will its solve some of the problems that are raised here ?

A dremel is to weak for metals and wood for that matter, Bare min. I would use a rotozip and cutting and low feed rates on machine.

i post this reply on your comment (joe2000che) only to understand

but ive done this with my dremel (not on cnc platform)
http://www.gruntville.com/phpBB2/viewtopic.php?t=12881


i really need to use the dremel becuse im not in the usa =\
and in my country its a problem to get half of the stuff i need -=\

are you sure its imposible ? (slow speeds maybe and im using dimond bits)

no not impossible, but the speed you cut by hand will be the spped i would use on the machine.

[Yonchi]

why dose a dremel is not so good for cnc's ? maybe i could compensate it by modifying the design ? or is there any other tool that i can use that i can find in a tools shop (and is cheap )
thanks for the help
