In this video we wire the CNC router machine to it’s newly built stepper controller and prepare all the pins that go to all the varies switches and motors. I show some of the work around that were necessary to eliminate false switch tripping from noisy lines. Also shown are some of the important Mach3 […]

This is a followup review of the eBay 936 soldering station. We used this product for over 20 hours and it worked well for our latest electronics project. In this video we take it back apart and see how the insides are holding up after use. The original review video can be found here: 936 […]

This is the final video in the homemade CNC controller series. We finished up by constructing motor wires and a 3D printer breakout box to house the pins of the home and limits. Watch the build in it’s entirety here: https://www.youtube.com/watch?v=4ZXfSJZRK4E&list=PLYqy2KdNTccMRHi6F9hFxSS5fdZ5g_039 DIY CNC Stepper Motor Controller Project – FINISHED! The Guru Brew is a weekly […]

I went on a mission to confirm if I could bend plastics such as plexiglass or Lexan with any precision of accuracy. I went forward and built a crude machine using scrap parts for my testing after researching other designs. These are the results of my findings… I was very surprised. The Guru Brew is […]

First test of the new homemade CNC motor controller using a computer and a stepper motor connected. Also we test the on-board solid state relay for spindle control. V-Reference (VRef) for current setting to the motors is briefly discussed. Connecting and Testing CNC Stepper Motors and Spindle Relays The Guru Brew is a weekly entertainment […]
