@phaedrux I'm sure it's more a matter of when and not 'if'. I've already made one silly mistake from ordering parts at like 2 in the morning... forgetting about the v-wheels, I ordered some Misumi extrusions to make I a bit taller, and replace some of the 2020 with 2040... totally forgetting they're not v-slot. Oh well, just more of a reason to try out these rails. I've only really had time to clean up the extrusions that came in the kit and sort everything out... will get there eventually.

Oh wow, just catching up. Those came with your PC wheels? Yikes. There are some on Amazon too, but I'm not sure how much better they'd be except probably easier to return if they're a mess, amazon pc wheels 20 pack. $3 and change per wheel might be worth checking out. I almost picked them up, but I'm still interested in the potential to use some of these guide rails I have laying around.
My kit was supposed to show up today, but I got off work today late today, and my wife decided she had somewhere else to be besides at home waiting to sign for my package(joking, of course)... so until tomorrow. I think just about everything else has shown up. I got my delta back up and running, so I'm starting to print parts tonight. I probably won't get to start actually building until this weekend though.

@phaedrux Thanks for the tips! I've definitely learned some of those the hard way building a couple deltas. I have a nice stash of t-nuts ready to go. I'm holding off on the PC wheels for now, because I have some extra linear rails I might try to see if I can work into it. That's good to know about the Delrin wheels though. I never had that issue on a delta when I was using wheels, but then again, I could see how this would stress them a lot more than a delta. And I definitely picked up bunch of the metal L and T plates, and the 90 degree corner brackets. Parts should start trickling in this week. I'm still waiting on a part for my delta to get here. I held off on installing one of my old extruders because I thought it would get here faster. But I've been pretty busy too, so I still have a lot of parts to print lol.

@phaedrux Awesome! Thank you for the extra pictures and explanation! That makes a lot more sense now, and looks a lot sturdier! Thanks for the tips too! I'm looking forward to working on it!

This is a really pretty build, and it's made me pull the thread on building one. I just bought a kit and am looking at what other parts I'm going to need to buy. I definitely like some of the changes you've made and used, and plan to use some myself. Looking through your pictures and this thingiverse file you used (https://www.thingiverse.com/thing:2401504), and I'm not getting how the lead screws stay secure in the flange bearings. He said something about using 8mm clamping collars, but I'm not seeing how that would keep it any more secure than the toothed gear. Am I missing something? I looked through your pictures, but couldn't from the angles. Thanks for sharing your build!
