    Clough42 ELS for my HF 8x12

    Clough42 on YouTube is doing a series on developing an electronic leadscrew for his lathe. I am following the series and implementing his ELS on my Harbor Freight 8x12 lathe. This is my build so far.

    Encoder mounting. Encoder: OMRON Rotary Encoder E6B2-CWZ6C 1024P/R 5-24v

    I have it all working on a breadboard. I just need to get the PSU and all of the electronics in enclosures and mounted. Once I'm done with that I have some features of my own that I want to add.

    Check out his video series. Very complete and well presented. Go see James @

    Slowly moving along while I wait for boards to be available from Clough42. I made some temporary changes to the software to activate the power button and make it control a solid state relay that turns on the 48 volt PSU for the stepper. I also got my display case done except for engraving the labels. The buttons are machined from Delrin. It's hard to get good pictures of parts that are so shiny. I used the Tormach Super Fly to face the display. That thing leave an awesome finish.
