A goal of mine for a long time has been to create Acme nuts for my prusa reprap. Creating them is actually easy, but figuring out how to do it is not. I used a threadmill on my Taig to create these out of Derlin. These will drop into the x-ends of the prusa and allow me to use a 3/8-12 acme rod. I expect them to significantly improve the smoothness of the z-axis and reduce the torque on the motors. Without further delay, here are the pictures.
I’ve begun working on a second Prusa build. There are a few reasons why, which I’ll cover in a later post. I ran out of 5/16 nuts, so I can’t complete the build this weekend. Take a look at the new color scheme. She has been dubbed “Viper”.
