Your machine came out very nicely it*guy ! And the works You've done looks good too ! :)

Hi it*guy,

Please see PM :)

Yes, I'm using NEMA23 425 Oz-in steppers.

I don't understand what all those loading's in datasheet means. I just try'ed and it worked perfectly. :D

Thanx :cool:

In case someone else whants to see it too (view it on 720p):

I'm not sure what do you mean. Can you show (mark on photo) what side caps of whitch carriage you mean?

I made some progress with this machine.

Now I'm little confused about connecting all electronics. Actually its about wires I'm confused. From electronics enclosure to all steppers cables will be...

Sure I was considering about anodizing, but for now its too expensive :) for next machine - I think I will make alu parts anodized.

Posting update of my build.

Mounted all steppers, racks. Drilled and fitted echain holders, tomorrow I will paint them.

Like CarveOne said in earlier post - I had X axis "A" arms misaligned,...

Some time passed from last my post. I have made some enhancements to my project. I have welded electronics box. There will be an water tank for spindle cooling, and separated with plexiglass wall -...

No machining, I did a little sanding and thats all. I will paint all steel tubes next week, now its pretty much rusty.




I attached screenshot from linear bearing spec's, but I dont...

Update:

All axis moving good. But Y axis (the longest axis) is little...

Hi All,
today I nearly finished Z axis. I have enjoyed this assembly. There was no errors at all. Z axis was attached to Y axis to try if the height of Y rails is ok = perfect fit !
Attaching some...

Today is great day - got the package from USA. CNCrouterparts R&P system for NEMA23. :wee:
I hope to get rest of the parts till 2012 :)

I'm not trying to make shiny parts, just remove oxidation. I want only aesthetic look (I prefer brushed Al look over shiny :) )
Thank for notes, I will post results.

I found this ScotchBrite product (pic attached) in my kitchen... I hope my wife wont find out where its gone :D
It gives pretty good result. But I would prefer more "electric" solution :D (like...

Thank you for reply. I will try find steel wool in Lithuanian shop's. But here, almost as always are no such things that you can easy buy in other country's... So, maybe there is alternatives ?

Hi All. I was bussy with my other (non cnc) project's but its time to move on with this. Attaching pictures what I done so far. Now I'm waiting my order for all other cnc components (including...

Hmm, is my purchased and listed few post above vacuum pump powerfull enought to connect directly to vacuum table ?
P.s. what tubes should I use ?

I'm here with a little update.
And need some help with vacuum system.
I dont have any experience with vacuum system at all. I have draw'ed pic with components (missing vacuum switch'es, cause I...

Hi all,
its me again :)

A little update.
Few design renders and few photos of cutted aluminum parts. Sorry for quality of photos, those was taken with phone and poor light source. Parts was...

I have decided make vacuum table. From earlier CNC machines I learned that job holding with clamps isnt good.
But I'm totaly new to vacuum and need your help guys to setup this system.

I have...

well,
I decided to try r&p and see the results my self.
I have redesigned main table frame. surface on table will be ALL in use.
Extended Y axis. So cutting area will be 1700x1200mm.

What you...

I'm not sure how to calculate rpm's. But one person calculated:
the 1500mm long 2005 ballscrew this will be about 700 RPM, so would be 3500mm / min.
Is this enough ? What speed you guys have ?
...

Hi again.
After talking with few other CNC peoples I'm confused...
They says that R&P is not good thing, and I should go with ballscrews (preloaded with no baklash).
If it is so, I should change...

Sorry guys for project delay.
Here is new X axis assembly. I decided to bolt instead of welding X axis beam.
What you guys think ?
Here is a short video to demonstrate what I mean:

X axis...

I would like to hear "CNCROUTERPARTS.com" opinion about backlash. Cause I will be using his R&P system.
Maybe someone can write his experience in using "cncrouterparts" R&P system.

Thank you !
I have posted private msg.

Hey,
thank you for your post ! Can you tell me more about R&P that your friend has used ? what mod it was ? maybe some pics you have ?

Hi, thanks for your post !

All cuttings will be made with water jet cutter :) (even tubes will be cutted with it, to maximize accuracy). All aluminum will be first cutted using water jet and then...
