Dead Thread Walking!

Dead Thread Walking!

mines still unfinished...it does have leadscrews - i went with 1/2" 8tpi 2 start leadscrews and leadnuts. and the powersupplies are wired. 3 atx supplies in series for 36volt, ~9 amps. no motors or controller, though.
im thinking about the 3 axis 200oz-in kit from hobbycnc...i think that will be plenty for the machine and my needs. so is there any g-code to cut out this lumenlab/joe 2006 machine. i guess if i got mine working it would cut out the parts for this new model. it looks to be considerably stronger than mine, with the torsion boxes and all.

I know he's given out the g-code to people who've ordered kits of his previous machines. Its probably worth PM'ing him at Lumenlab to see if he charges for it. It does look like a solid machine.

I almost forgot to post that book that I was using.

i ordered my steppers from hobby cnc. i went with the 200 oz, 3 axis controller. seemed to be pretty reasonable. with 14 feet of the multiconductor wire it was 225$ shipped. hope it isnt too bad to assemble, it looks like i have to populate the controller board and solder all the components myself. suppose thats why they call it a "kit", lol. i've built a few wideband oxygen sensor controllers and it had lots of parts so i think i am up for the challenge. i also ordered the spider couplings from motor to leadscrew from enco. shouldnt be too long, now.

Let us know how it turns out for you. I am still aways from needing electronics so I havent bought any yet. I am going to use a 4 axis controller because I am going to have two steppers on my X axis. Do you have any pictures yet?

i have the sosylva plans and for stepers i am using the http://www.xylotex.com/ setup with the 497oz but i really like to make a metal machine and don't have much idea in this can some one hel;p me out i like to know what are good desent leadscrews and all the setup

Why 2 on the x axis?

you dont need to use the 4th axces to make that work on the x axis. this router in this pic is using 2 900 in oz steppers that are run in tandum using only 3 axis to control XYZ movments. the x movement still needs 2 drivers for the 2 seperate steppers but runs one backwards in a sence. that way they both run in the same direction at the same time.
you may want to consider a rack and pinion style of movement so they dont bind up and cause damage to your router. when they move fast they may not be in sink.

 

[blfuller123]

What do you mean run in tandum? I was just going to use a four axis controller and use Mach 3 to run the 4th axis as a slave. How would you wire something like that up?

 

[BeanAnimal]

Do you feel you really need the dual drive to move the gantry?

 

[Fluxion]

IF there is anyone interested in building the larger of the Solsylva designs and have some questions I might be able to help.

Here is a pic of mine after painting before I added the steppers and got it running.

I can get a current picture if anybody wants to see it. I have it up and running and I have used it to cut some parts but it still isn't finished. I plan on adding an A-axis soon.

 

[blfuller123]

Bean,
Its not that I dont think a single stepper wont drive it, I just want to make sure it doesnt have any kind of racking. I might try it with one screw before I order my electronics and see how it does.


Fluxion,
Looks great. Are you happy with its performance? What have you cut with it?

 

[spazz]

you can run it single screw if you have the screw under the deck in the middle of the gantry. that way it pulls and pushes evenly.

 

[blfuller123]

Yea, I am trying not to do that though.

spazz, I think I saw a machine like yours on ebay the other day. Way out of my price range though.

 

[guido_kp]

well the cnc fairy made a delivery today! i got the controller, steppers, and the cable by mail. pretty fast considering it was ordered just a couple days ago. i've got some crappy pix via my moto slvr cell phone, but thats it for now. i dont have anyway to host them, though. the controller was easy to assemble, i put it together in about 2.5 hours. thats as far as i got, though. still lacking the lovejoy couplers from enco. should be in next week hopefully. Fluxion, thats looks like a nice machine...what have you cut with it? What kinda stepper/controller?

 

[BeanAnimal]

From what I gather MACH3 is the only way to fly. Is everybody here of the some opinion?

 

[thesaent14]

where can i get a copy of mach3

 

[spazz]

yes mach 3 is the only way to control a cnc router. its simple yet complex if needed. the biggest thing is to go slow when you first start out so you dont crash the bits down into the deck. i did that a few times. ha ha ha its not a pretty site. :eek2: :eek1:

 

[tinygiants]

Try going to cnczone.com There are links there for everything you could need.

You can get Mach 3 here.
