Hey guys!

I'm starting the build on my next machine - machine #1 cuts good enough if i go really slow - otherwise it flexes... so I've started building the next one - better, stronger, faster

here's a preview picture and for the full story - go HERE

Whew, glad to see you separated it into more than one page! Good luck!

Wow, its amazing how fast you are. (do you have a day job?).

I think I started my first before your first, and now you are on your second... and I'm not even done with my first yet. Getting close though.

The new machine is looking good. I wish you well.

[BackyardWorkshop]

haha I sure do (have a day job - writing software)

Lets just say I'm a little obsessive compulsive (to say the least) LOL

@gir - yeah - I too got tired of waiting for that one pager to load and scrolling to the bottom

Hey guys - an update on the build... I was still getting some racking with those linear bearings so I started working on a new linear bearing idea - here's a few pics - but the full story (and one new video) is on my site (link in first post)

[nwc-cnc]

your link to the "full story" is dead.

Thanks for letting me know - I changed the category and that changed the link... duh hehe sorry

any progress today Jamie ?

[BackyardWorkshop]

I made some but not much to speak of... I'll be on it a lot tomorrow and I'll take some pictures and update

[nwc-cnc]

I will be following this thread, should be a good one.

[BackyardWorkshop]

Thanks

Actually I worked all weekend on the machine - but I'm struggling with the linear rails and motion system... Everything I try seems to not be good enough

and I think I figured out one problem... The angles I was using to hold the aluminum together just doesn't seem to hold well enough... When I was testing to see if the latest idea would rack - they loosened - so now I'm trying to make my own one piece corner braces from 1/8" think angle aluminum... I will upload pictures of the corner braces asap... I hoping that one piece will hold better that two seperate pieces, and I'm pretty sure that the 1/8" aluminum angle is stronger than those angles too (I can almost bend them by hand - but not the AL so that's my "gauge" )

Stay tuned... hehe

[nwc-cnc]

pics?
maybe the group can help figure this out with you....?

[nwc-cnc]

I ran home from work (car), so I could login and see your progress....

still no posts, eh?

Like you, I purchased some bars as well (20ea.) from that guy on ebay!

I am also wanting to create my own linear rail system, except for the Z,
which I bought a K2-5inch Z Axis.

I am really hoping that you come up with something great!

[nwc-cnc]

Ok Jamie....Happy 4th!

I have some off the shelf AL angle.... 1/8" thick x 1 Inch

It not only fits.... it "Snaps into place" !!!!

Got the 1 inch angle at Home Depot.....

Note that it only is a perfect fit with the 1/8" thickness,
also tried 1/16" which was way too loose.

Well, do you think this will help/work for us?

[BackyardWorkshop]

THAT is very cool - but I would be afraid that it would slip into the slot on one side without any screws or anything... still that's a great find!

so - actually on my machine.... sorry no updates in the last week - I've just been trying different things and didn't want to post until I found something that worked.... and I think I got something that is going to work great - as soon as I hunt down the digital camera - I'll take some pictures

but I should have the Y axis completed today - so there will be a good update tonight for sure

[nwc-cnc]

ok, so I decided that you may be correct on the slip into one side idea...
so..... I tried to push on the angle, it would not budge, so.... I tried to remove it from the extruded bar.....

it was so tight I needed a screw driver for leverage!

I really think this deserves some additional consideration...... but am waiting to see what you have come up with.

[BackyardWorkshop]

sorry - didn't get a chance to take pictures today - but I will for sure tomorrow...

I did make some progress I think today but it's not complete and I want to finish the idea and make sure it's good before I post again (as this is my third idea LOL)

Stay tuned

[BackyardWorkshop]

I think I have what I want - at least there's no racking so far! - as I say in my post - I'm not "sold" on what I have for the X-Axis - but the Y-Axis I think is finally done - of course I'll have to redesign my motor mounts and screw holders - but that's OK I was going to do that anyway because when I had the 5/16 screw on there for testing it was whipping like crazy - so I have to move to a thicker lead screw anyway...

I think it's about time I worked out a base for the machine as I still have those little 2X4s holding things up LOL

[daclearwater]

have any pictures of CNC1 on your site, didnt see them, maybe i missed em.

i'll be checking back to see progress on #2!

[BackyardWorkshop]

oh gosh there are a ton of pics of the first machine unfortunately they are all on one post! hehe so it might take a few seconds to download...
