Doesn't look like my new version posted on Thingiverse has gotten any activity.

If someone needs a different variant, please post over there...

@ccs86 Thanks for the "v3" updated design. It looks good, however, is there any chance you could make a version for the stock 11mm bronze bushings and 6mm rods? Either that, or provide STEP files for the design? I tried to edit the STLs to fit my stock bushings, but it's really a chore to work with mesh files.

I've been using an earlier version of your "v1" design for a few years, except I shimmed the bushings with paper to make up the difference between the 12mm design and the 11mm actual bushing dimension. This worked for a long time, but now the bushings are starting to slip out of the blocks, so I figured it's time to upgrade to the proper blocks.

Okay guys, sorry they never fixed this. Thanks for being patient. I have actually done a lot of development on my printer recently, and first converted from 6mm to 8mm crossed rods, and then to crossed linear rails!

I decided to ditch the 1 piece XY block design, since I was really tired of messing with the pulleys. So, rather than reupload the "v2" design, I just updated my "v3" 2-piece version for normal 6mm rods.

I did my best to list out the hardware stuff. Having a good assortment of M3 screws is a good idea. I linked the m3 heat set nuts I like. If you are feeling brave, you can just cut the old XY blocks off and install these without having to remove the pulleys and perimeter rods.

@ccs86 It's been a couple of months and the new version of the XY blocks is still inaccessible on Youmagine. Any chance you could re-upload the design?

Thanks for confirming the issue guys! I reported it to Youmagine too, but didn't even hear back from them. When you look at how often updates are communicated to the community through their different social media channels, it seems they abandoned the platform long time ago ...

Cheers, Tom

I'm actually getting that same error too, but I can access the edit page. Very odd.

I submitted a request to youmagine to fix this issue, and updated the link in this description. Hang tight. Hopefully it will be back online soon.

@plasmasolutions I can confirm that I also get a server error 500 when trying to access the v2 version of the xy blocks. Also, the link to access is wrong because it tries to go to the edit page, but you probably figured that part out.

Hi Lars, do you also have issues accessing your v2 version of the xy blocks? Is there any other way to get them?

I always get a server error 500 when accessing https://www.youmagine.com/designs/lars-v2-ultimaker-xy-blocks. If anyone could confirm that, I'll notify youmagine...

Good morning! I am still testing, but so far, so good.

I was able to modify one block in Fusion, filled in the limit switch holes for stiffness, then thinned the back for clearance. This meant that the retained nut and part of the machine screw head that clamp the bushing sat proud of the surface, so once I had enough clamping pressure on the busing, I ran the back of the block along a fine metal file until everything was flush again.

I haven't tested this yet with the bed all the way down, I think the Z screw will come in a bit and I will probably know for sure then.

I would upload this mod, but a) I don't know how and b) I'm not yet confident that my solution works full travel.

I will look at your modified version as it may be better than my work around. Thanks for continuing to support this!

Cheers

John

How did it go John?

I finally got my new design uploaded:

https://www.youmagine.com/designs/lars-v2-ultimaker-xy-blocks

Thanks for your response! I'll file down the one I have and see how much material I need to remove, will see if I can post a comparison here.

Cheers

The fastest fix would probably be to just file or dremel the interfering material away.

I actually have a new design for these, with a separate rear block, for even lighter weight and no clearance issues. I'm not sure when I'll post them though.

Just installing these on a UMO without the heated bed. Having the same interference issues on rear x axis, the block hits the lead screw and vertical rods. About 0.3mm from what I can see.

Nice work catohagen!

How did the sizes work out when sintered?

@Jeffrey Burdick: Check if your pulleys are not too close or too far from the back panel.

I just printed these and installed them on my UMO+ and found that the X axis block closes to the Z axis rods actually interferes slightly. It's not by much, but it will noticeably stick when moving past them.

I'm guessing since no one else has experienced this that I'm alone in this problem. Odd.

Okay guys, I went ahead and posted the requested configurations. There are now 6mm and 8mm rod clamps, and 4 configurations of XY block for all combinations of 11mm/12mm bushing OD, and 6mm/8mm rods. Enjoy!

Love these:-) I'll print them this week for an Extended Ultimaker. There is already a request for 8mm crossrods. Are you planning to do so? Would the original files be obtainable? You'll get them back when changed. Otherwise I'll have to redraw your design:-)

I was thinking about making a different clamp for MXL belts, but just had a thought that if you scaled them a couple percent in Z alone, that would probably do the trick.

Enjoy!

Are you running the original MXL belts? I designed these for the GT2 belts I am running (I would highly recommend them, great value upgrade) and they are possibly thicker.

I had initially designed the GT2 belt profile into the clamp for super strong lockup. But you lose the very fine adjustability that the flat clamp gives.

I like them very much. I will print new ones now the printer prints much better.

I noticed the belts didn't clamp well, so I put a peace of rubberband between. Works great.

Which size bushing 11mm or 12mm?

Hello

is it possbile for you to make it for cross rods with 8mm instead of 6 ? :)
