If you have any wiring to do on your 3D printer or other CNC machine, you are going to need to crimp the correct connectors. By request, this video goes over all of the types most regularly seen on these machines, the tools required and how to crimp them properly. Once you’ve done it the right way you’ll wonder how you ever managed in the past!

Thanks to Jason Friedland for requesting this video. The timing was perfect for my Rat Rig V-core 3 build:    • Rat Rig V-core 3 build
