Not all three axes, just Z. This eliminates the flex from the printed bearing blocks and hopefully a smaller footprint.
Speaking of,
The rated moment of a 12H is 36N-M (26ft/lbs) ummmmm I guess 4 per side was overkill. Lets cut that down to two per side. Even a knock off should be plenty capable as a pair to handle the full weight of the LR under full cutting loads. That cuts $50-$60 off the BOM right off the top. Niiiiceā¦
Anyone see anything wrong with that??? Think in terms of just swapping the current LR Z rails. (it is not that but if that would work so will this)
What do you figure the moment is during a sensible cut?
Rather, during a reasonable maximum cut load on a reasonably large sized table⦠reasonably speaking
Do you need to install every screw to reach those limits 
I always have like 9lbs max load stuck in my head, I am not sure where that came from but I know that is very high from an average cut. That 9lbs is extremely close to the blocks. As 2 inches delta Z almost directly in line with the front block. The entire mass is centered betwean them pretty evenly (as far as I can tell in CAD). So we have the mass and the load.
You know I will have to include all the screws or I we will never hear the end of it.
Dang this changes everything is such a good way. So much more room.
Yeah. 2 rails per side should be more than enough.
Two bearing blocks per side. instead of two per rail.
The only issue I see is now there is a large pivot point on the parts. I will stagger the blocks to try and help that a bit.
Oh. My missunderstanding⦠I was trying to figure out why youād think youād need 4 rails on each side 
Not sure about only two blocks on each side, though. I think even if you offset them from each other, youād still have a single plane of rotation, itād just be at an angle instead of straight across.
Yeah, Iām printing some parts to test that a bit.
If the wheels are flat and that defines the plane/line from which the rotation happens I think the further off that plane the harder it would be to rotate. I am actually most worried about the printed part at that point. I can flip it so the cut part has the highest load.
Well, it makes more sense to flip it now. Boy does that make things much more awesome. I know this is terribly out of context but I hope it helps to know I am making progress and still super excited.
Little over a month before weāre in the new place. You got time. 
Just go get the garage, you are going to need that sooner than a month.
Iām waitingā¦
I am frustratingly close⦠One last tiny hurdle. I think it is mostly figured out. After that just a couple belt mounts and printabuility tweaks, I hope.
I get stuck fighting not making things biggerā¦sometimes an extra 5mm is no big deal. Zoomed in full screen it can look a lot worse. I almost had it all able to be printed on a 200^3 printer, but donāt think I can squeeze it in. So far it looks like one piece either needs a larger printer or it will be a CNCād flat part.
I have a full day and a half with an empty house starting tomorrow so, I plan on getting a lot done.
I see a 300x300 Repeat on your near future ![]()
![]()
I should qualify that. I am frustratingly close to seeing if this new concept even worksā¦
If you are that close, I will wait to try Klipper on the Repeat until after the beta test.
