CMS router table fence improvements ( micro adjust using crown stop) "updated"

[GarryMartin]

I did something similar some time ago, but I wanted a solution that did not make any changes to the CMS plate or its components, so I toyed around with a 3D-printed solution. I never got around to finessing it because it worked fine at a particular point and I then moved on to other things, but if anyone wants to try it for themselves, I've attached the STL files you'll need as a ZIP file. All it needs is some longer bolts for the bottom part where it connects with the plate and the screws etc. from the Wixey install.

Otherwise things are friction fit or you can apply a little glue if you feel the need.

Hope someone finds it useful.

Thanks for posting Garry...nice install. I don't have a 3D printer but I really like the method you've chosen to mount the DRO display. Maybe I'll take a look at machining something similar to that from Delrin.

sure

[member=11629]GarryMartin[/member] do you remember if supports are needed?  I'm guessing PETG will work fine for this?

[member=11629]GarryMartin[/member] do you remember if supports are needed?  I'm guessing PETG will work fine for this?

PETG definitely fine. Mine are printed in that. I can't remember regarding supports though. Definitely not required for the MFT support, and I don't think so for the bottom. Pretty sure they're needed for the top but I can't remember off the top of my head which orientation I printed in.

Did the parts work?

Well, I finally had the opportunity to fit the Wixey DRO to the CMS.

A huge  [thanks]  to [member=11629]GarryMartin[/member] for the bracket design and the documentation and a huge  [thanks]  to [member=71889]festal[/member] for the actual 3D printing. She's definitely a thing of beauty.  [smile]

I'll show the completed/assembled display first and then talk about issues that may or may not be unique to my machine.

The bracket installs from the top, just lightly snapping on to the V-groove extrusion. It can be easily slid along the front edge of the router table and can be moved to either of the extension tables if need be such as when using the sliding table.

I do like the concept, [member=44099]Cheese[/member], but I think I might prefer to locate the read-out above the CMS' table, say, back next to the Sparktrician-model power switch where I can see it, and where it does not interfere with the sliding table's rail.  Much to be explored in the future, methinks...  [big grin]

Ya Sparky I agree...all this concept stuff is great but the real "Come to Jesus" time is when you fire up the equipment and actually start to run product through it. Let's see what happens... [smile]

Nice [member=44099]Cheese[/member]

 

[GarryMartin]

Looking good [member=44099]Cheese[/member]! I'm not sure it would interfere with the sliding table at all [member=7493]Sparktrician[/member] and it's very easy to clip on/off if it did interfere with anything for any reason.

[member=11629]GarryMartin[/member], I checked very carefully on my own CMS before making that comment.  I still say that I would prefer to have the read-out up and behind the working surface of my CMS.  YMMV...  [smile]

Well I think I finally figured this thing out, I mentioned earlier that there was a unique issue with the fit of the Wixey bracket to my CMS aluminum V-extrusion rail.

When [member=11629]GarryMartin[/member] originally designed the Wixey DRO bracket, he designed it for use on a CMS-VL table. On that table the aluminum V-extrusion is open on both ends. On the CMS-GE table, the aluminum V-extrusion is captured between the cast aluminum bracket that holds the 2 legs. This leaves a small area where the the Wixey bracket can contract and that makes it just about impossible to remove the Wixey bracket without using 2 screwdrivers to wedge open the bracket and remove it from the aluminum V-extrusion. It wouldn't take too long before the bracket would start to crack and break. This is what it looks like in photos.

Open style aluminum V-extrusion on CMS-VL.

The part of the Wixey bracket that got caught in the recess is the small radius lip highlighted in green.

Once I removed the lip with a sharp chisel and a little file work the problem went away. The bracket is now easy to attach...easy to remove.

"The problem with 3D printing is that you still need to machine the part when you're done to get to a working final product"

Just kidding around, Cheese. 

Looks great, and can probably be updated in the file for others when they print!

 

[GarryMartin]

[member=44099]Cheese[/member] Mine fits fine on my CMS-GE (and even my CS 50 for the hell of it!) but my extrusions are more flush-fitted than yours - I don't have the slight difference in heights you highlighted in blue. The bracket should clip on and off without having to slide it off the ends too; although I could make that a little easier, I was more worried about it being knocked off accidentally than making it very easy to get one and off but I could modify the part to lose the lip or reduce it. If I find some time to take a look, I'll come back to the thread and post an updated model.

Thanks for chiming in Garry...who'd have thought? I checked the non-flush fit on both of the sides and they are different. The RH side in the photo is off by .040" and the LH side is off by .025".

Later today I'm going to check to see if I can loosen and realign the leg casting to be flush with the front extrusion.

Later today I'm going to check to see if I can loosen and realign the leg casting to be flush with the front extrusion.

There are 3 Torx screws on each end that can be loosened and that allows the front aluminum V-groove extrusion to be relocated slightly and more closely align it flush with the corner leg castings. It's not completely flush but both are now within .008" of being flush.  [smile]

Willy [member=7493]Sparktrician[/member] this is for you.  [smile]  I decided to move the DRO to the rear of the table just for giggles and decided I actually like it better in that position. It's completely out of harms way but yet still very visible. A slight modification to the existing metal bracket or maybe just a new metal bracket will take care of everything.  [cool]  I believe that's where mine will permanently reside.
