Hmm, the metal spacer comment is interesting.

How do you think it could be worked into:

http://www.shapeoko.com/wiki/index.php/Upgrade_Overview

Will definitely have to keep that in mind as I'm upgrading my machine.

What's the opinion on that page? would it be worth adding it to the sidebar as the first link of the Upgrades section?

Also did you get your spacers from McMaster? Are you using aluminum, stainless, etc.?
I squared up my Y axis frame when I built it the first time. Since then I have only rebuilt the X and Z.
I try to spend a bit of time squaring and aligning at each step. Then once it is all together I go back and recheck everything.

I have picked up the spacers from lots of places:
Inventables
OpenBuilds
Buildlog store
Ace hardware
McMaster-Carr

What you want to look for is screw size 10 or 12.
Sometimes the 10s fit just right, sometimes you have to drill them out.
The 12s will always fit but are a bit loose.

I am not sure where they would fit into the upgrade overview. They are a great bang for the buck upgrade.
I think the overview page is probably worth adding to the Upgrades Section but it could use a bit more work as well.

IC,

Nice mods. I am also using the Dewalt DWP611 (http://www.shapeoko.com/forum/viewtopic.php?f=8&t=1222). I was wondering how you affixed the dust shoe to the router? Also would you be willing to share you the CAD files for the shoe?

Also since I extended my Z-axis with my mod for an acme screw. I was able to make a new plate similar to Eshapeoko. The plate allows for the top to be tied together with spacers. I also added another set of V wheels so the ACME nut has wheels above and below. A threaded spacer was used to tie the bottom V-wheels together. It removed some of the deflection but I still have about 0.1" deflection at the tip of the endmill if I put some serious pressure against the Z-Axis. Since I did not want to hijack your thread I put the pictures in the link above.

I bought some non-hard coded openrail and was hoping the remaining deflection would be removed if I used a piece of 4040 extrusion and the existing delrin wheels. Do you feel that the metal wheels would remove some of the deflection? If I go with metal wheels how does it effect the spacing? Also since I don't want to redesign the X-motor plates do you think it is worth going 4060 and buying larger spacers?

Thanks

Wow ok here we go...

The dust shoe is attached to the bottom of the router using the screw holes that hold the spindle lock.
You have to find some screws that are about 1/4" longer. I got mine at the local Ace hardware
I modified the diverter found in this forum post:
http://www.cambam.co.uk/forum/index.php?topic=2341.0

I will add the files to this post later tonight when I am at the computer that they are on.

I think that tying the bottom V wheels together probably does more harm than good because it does not let the eccentric spacers work independently. It could cause them to sit cockeyed on the v rails.
I have a provision in my setup to add another set of V wheels to the Z axis, but I need to order them.

I don't know if the 4040 I had before was better than the two pieces of makerslide or not,but I do know that the steel wheels on the hard coat openrail helped a lot. I has a bunch of really sloppy delrin wheels, the bearings just fall out. So the steel wheels are awesome. The openrail wheels are the same size as the delrin ones. I think that you are better off with the 4040 if you don't want to redesign your plates going wider will just cause you more problems. :)

Re: Is this thing even a Shapeoko anymore? Now with video.

Here is a video of my new setup cutting some DW660 mounts at 2400 mm/min. 2 flute 1/8 endmill, 10000 rpm, 1/16" passes,
The high pitched whine is the UHMW vibrating against the spoil board. As you can see it is pretty trashed...
I resurfaced it this afternoon and it looks (and sounds) much better. :)


Here is a video of my modified shapeoko vs my stock shapeoko.

I use my highly calibrated hand to push on the Z axis of both machines and as you can see there is a big difference!
It sort of looks like the big machine is moving when I grab it, but it is just my hand moving.

Here are the drawings for the DW611 dust shoe.
They are in no way complete but should be good enough to get you started.
It is in AutoCAD 2013 educational format so if you try to print them there will be a bunch of watermarks on it. Sorry.
If you need it in another format let me know and I will see what I can do.

First: Very nice upgrades and changes! Thanks for posting and sharing!
Second: Can't believe we are three pages in and no one has answered your question - "Is this thing even a Shapeoko anymore?"
According to my official** categories (see http://www.shapeoko.com/forum/viewtopic ... 5386#p5386) I would categorize it as

Custom Shapeoko or Shapeoko inspired --- Start with Shapeoko design but some "significant" changes

Third: In regards to your comments
Improbable Construct wrote: I seemed to have a lot of delrin V wheels that would let the bearings just fall out.
I didn't even have to press them in. So I think that the metal V wheels helped there.
Did you need to press the bearings into the metal V wheels? Do you think it the fit between the bearing and the V wheel or the material (steel vs delrin) that helped more? Or was it the "wider" design of the OpenBuild V wheels? I like that the OpenBuild V wheels (both metal and delrin) cover more of the bearing width which should be an advantage. Probably impossible questions to answer, I know! But I am debating the steel vs delrin question and thought I would ask!



** not really official - just something I wrote

IC - fantastic work of course - so this new "brush" material on your dust shoe - it looks to be some sort of heavy felt/fabric or other? What is that stuff?
Shapeoko #298, dual drive upgrade, acme z axis, open bed endplates and a slightly larger ("expanded desktop") work area!

Very nice design, looks really rigid. Fast too.
