In this video, I show the steps required to construct a spindle encoder for a lathe. 3D design files can be found at: GrabCad: grabcad.com/li... Autodesk: gallery.autode...
I would love to see a workshop tour, especially of your tools and all your machines if you have the time! Appreciate all your work and kind regards for sharing it with us.
As a fellow LinuxCNC guy I appreciate this. I have two Sears Craftsman 1960 series lathes... one has a damaged speed gear system so I was considering turning into a CNC lathe. I like your method of mounting the quadrature encoder... I will have to do something similar for mine. Thanks!
I'm curious why you selected a 100 PPR encoder. I assume this was all the resolution you need for adequate thread timing. But is there a simple logic to what the minimum should be? Also I assume there's a zero pulse position output, and that's the key to the timing, with the other pulses just used to track spindle RPM. I'm also impressed by your CNC pallet that effectively is just a bolt on, along with this encoder mod. Seems that removes all the issues of the power needed to drive the feed screws.
Hi. There is indeed a zero pulse output in addition to the quadrature outputs. I reduced the PPR in order to work around a LinuxCNC latency issue that I need to resolve. Ironically, latency wasn't an issue with my old i686 32-bit system, but is definitely a problem with my new i7 64-system ! The CNC add-on has been a brilliant tool. I hope to make some further improvements in the near future, so keep an eye on my channel. All the best.
Could you go through how you set up the table - how it's installed on the lathe? I keep going back and forth on the idea of a conversion, and i think this has the best chance of coming to reality for me! I've found a supplier for pre-built linear stages... they aren't cheap but without a mill or the time to design the parts, it might be the best way for me to go!

Nice job. We shared this video on our homemade tools forum this week 😎
sweet, neat, pro build. Thanks man.

Great vid thanks! are you from ZA? sounds like a ZA thats been in the UK for a number of years.

@@girvaw would love to know what improvements you have planned!

What is a lathe do u use?
