<p>OpenSCAD has <code>rotate</code> function which rotates the body around its origin axis.</p>

<p>I am wondering how I should properly get rid of branches that no longer have any purpose. Right now even if i delete them and commit they are still listed as branches in the properties windows for a particular branching root (directory).

<p>What would be the best method of automatically generating a Release Notes text file from a Team Foundation Server 2008 nightly build?</p>

<p>Hello everybody,
I want to print something for my family but the hotend gets clogged every time in the same part of the print. I tried:</p>

<p>So I found my mistake: It was the E-Steps I did wrong it over extruded. The best E-Steps per mm are 92 for me. The mistake took place because I took my E-step number from a Video Tutorial about my dual extruder. I found the optimal number by testing out; the formula I got for the E-Steps was in t... | <p>I noticed that on my Ender 3, if the belts aren't tight enough, I have a similar problem, but mostly when I print anything circular.</p>

<p>I have a community site which has around 10,000 listings at the moment. I am adopting a new url strategy something like</p>
