        <title>Sanity check: custom build sizing</title>
        <description> Hello all, just joined after playing around with my old anycubic pulley for a while as I embark on my duet upgrade that has turned itself into a full-on rebuild. After playing the OpenSCAD calculator, the various excel sheets, and reminding myself of high-school geomery, I think I&#039;ve got my sizing right, but was hoping the experts could sanity check me.. I&#039;m planning on the following;

* Ultibots Corners (https://www.ultibots.com/deltabot-2040-metal-corners-set-black/)
* Openbuilds V-slot extrusions -- 500mm horizontal, 1000mm vertical
* V-slot gantries -- [openbuildspartstore.com]
* 360mm magball rods
* Duet smart effector

My math indicates that will work and give me a ~330mm print height, right around 20 degree angles, and room for a 250mm bed.. I&#039;ve gotten a couple different results on this, so i was hoping someone could confirm I got my math right and this will work?

Thanks!</description>

Remember that your 330mm build height is only in the middle of the bed. Out towards the edges, you have somewhat less, depending on arm length and bed diameter.</div></blockquote>
<br />
Quite so. For my build (also 1m vertical extrusions, 360mm rods. Smart Effector and E3Dv6), it's 470mm at the centre and 420mm close to the towers.]]></description>

            <description><![CDATA[ That's right, the carriages don't need to reach the bottom. In the "Making it larger" section I mention that the 750mm long linear rails would be OK with a vertical extrusion length up to 1.1m.<br />
<br />
The carriages with integrated belt tensioners were from Robotdigg.]]></description>

            <description><![CDATA[ Thanks! I was actually just reading your site last night! I have a couple questions if you dont mind;<br />
1. your BOM lists a 750mm linear rail, but I believe you have room for at least an 800, if not a 900mm one? I am presuming it's because the carriages never need to go all the way to the bottom? Is that correct?<br />
2. <s>your BOM lists a motodis carriage from germany, then another one from robotdigg -- i can not seem to find either one, do you have a link by chance?</s> yeah, so i just figured out that means shipping :) But where do you get your belt tensioners?<br />
<br />
I suspect I'll be following your guide pretty closely, so I appreciate the help!]]></description>

            <description><![CDATA[ You can go a little bigger than that using 360mm arms and 1m vertical extrusions. Check out my delta build at [<a href="https://miscsolutions.wordpress.com/dc42s-large-kossel-build/" target="_blank"  rel="nofollow">miscsolutions.wordpress.com</a>]. I think the Ultibots vertices are the same as the Robotdigg ones that I used.]]></description>
