<p>I can't seem to understand the margins that Cura uses or how to fix them for my machine. Look at this:</p>

<p><a href="https://i.stack.imgur.com/5oD0d.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5oD0d.png" alt="Screenshot of Cura, depicting large grey area"></a></p>

<p>I can't seem to tweak the stuff under machine settings to anything that does this better:</p>

<p><a href="https://i.stack.imgur.com/FEd5k.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FEd5k.png" alt="Screenshot of settings"></a></p>

<p>Maybe a bit of dup of <a href="https://3dprinting.stackexchange.com/questions/645/cura-not-allowing-full-print-area-to-used">Cura not allowing full print area to used</a>, but I think my case is a lot worse and can't be explained by skirts.</p>
