I’ve wanted to build a top shelf 3D printer kit for a while, and now I present part 4 of the Rat Rig V-core 3 series. In this video we try out input shaping using an accelerometer, which was my primary motivation for building this machine. It didn’t disappoint and in my opinion represents a major step forward for 3D printing.

In this fourth episode, we also cover questions and comments from part 3, basic calibration, pressure advance and high speed test prints.

Next episode will see the fitment of the higher flow Slice Engineering Mosquito Magnum and a bunch of experimentation in trying to print a 3Dbenchy as fast as possible for the #speedboatrace challenge. We'll also add up the final cost of the build.

This kit was purchased with my own money, apart from the shipping which was provided free of charge by Rat Rig. All opinions expressed are my own.
