Thank you very much, that value is much closer. In any case, it is worth building with a thickness of 1.25 mm and testing how it goes.

In a triumphant victory tragedy for hoarders everywhere, my 60" 1.0 inch OD lowrider 2’s stainless steel X rails, I now realize aren’t plump enough. Of course, I’ll probably hang onto the LR3 EMT rails for the next 5 years… you never know!
Edit: Dang it, looks like “Rails ranging from 29.5mm to 32mm will work.” Oh well!
1” EMT has a typical ID of 1.049” and OD of 1.163”, so yeah - like everything with the word ‘nominal’, it’s just kinda sorta 1”

Doug, are going to be using your torsion box table for the new V4? Have you seen anyone making a table that folds up against the wall?

Early beta builds were done with printed XZ plates.
I’ve got several sets of printed plates, and several sets of aluminum plates.
You want the aluminum plates.
If you do cut it out of MDF, paint it with Tightbond III gule to add some rigidity, then as soon as you can use your awesome new machine to mill a shiny set of aluminum plates.
Did I mention you want the aluminum plates?
Ryan is providing the DXF files so people can cut their own out of whatever, or even linear extrude the DXF and then 3D print that.
Ultimately, though, you want the aluminum plates.
Edit- and you’d be hard pressed to find a better value than the aluminum XZ plates that Ryan has in the shop, if you’d rather not try to mill aluminum (which you machine absolutely will be capable of).

Looks like Bunnings has Galvanised Steel round tube.
Would this work? Would make it a cheap and easy solution for us Aussies

@vicious1 Thank you, i wanted to support you by buying the kit but it was $100+ for shipping, so instead im going to pledge in Patreon, hopefully that helps.
I will wait for the release

Finding tube/rail is a good idea for a new topic.
We went through this before I started the v4 so there should already be a list of sizes people thought was common and what it was called in your area. If you live in an area that uses metal conduit one of the three available sizes should work. If you are in an area that does not use metal conduit you are looking for one of the three sizes with at least a 1.4mm wall thickness, steel, No Aluminum, no carbon fiber, no cement. Stainless is an option, some closet rods or boat suppliers are other options. DOM Steel is okay if you are willing to treat it for rust prevention.

I think that’s at the very beginning of the development thread - will try to find it tonight!

That is sort of what it boiled down to right. You either have conduit of the right size or 30 or 32mm OD is what is going to be common? Adding the notes to the instructions right now.

Has anyone had success in correcting xz/yz skew using the V3D measurements on an X1C? I found that the M852 is M1005 for the X1C, but it seems it doesn’t support using the i, j, k values.
Oh and for those with an X1C, this post in the Bambu forum may help with the xy skew at least. About to run a test to see if what they say works (several have claimed success at least for xy skew).

Bambu does not current support Z skew adjustments.

I’m super curious if it does. And also what your score was from the Vector file. Did you use calilantern?

Dang, in that forum post apparently a Bambu tech said that skew corrections were in development. That was several months ago.

I’ll report back. Currently doing the baseline, I will apply correction and print again. Here’s where I found the stl that bambu provided along with instructions how to apply it. I added straight into my start g-code and saved as a new profile.

Oh and for giggles I’ll also print the Calilantern after the corrections but that will take a few hours. Some say it helped the z skew which I can see helping a bit.

Sounds like a great idea.
Its just a matter of understanding really that is required and what we can find locally.
We have EMT here too, but about 3 times the price.
If its needed, Ill spend it, no point saving a few dollars to have a poor outcome.
But if the cheaper tube will do the job, then all the better.
This is emt in aus.

The difference in deformation between 30x1.5 and 30x2mm on a length of 1400mm with a load of 5kgf is about 0,2mm… and this is considering only one tube alone, without any structure. I don’t think it will make any difference, but the reality could be different

Yes. I spent some time today modeling printed plastic inserts that will have the belt tensioners attached to them, and they will insert into the ends of the metal struts on my table. I had made these before — back for Lowrider version 3 — and I named them “table extenders” because it gave you additional cutting width. It will be the same way this time only they don’t have to be so exaggerated because the LowRider 4 is more efficient in its footprint.
Yes, I have seen some pretty impressive fold up tables here in the forum. I can’t exactly call to mind right now who did that. Maybe someone will chime in and link to it for us.
Congratulations @vicious1!!! Success is well deserved!!
