Centroid does sell Encoder cable and it is the right stuff! Made in USA shieled and twisted pair encoder cable. look at the bottom of this page...
http://www.centroidcnc.com/centroid_diy ... nents.html
and while on the subject of encoders....the encoders that centroid sells can be used as spindle encoders, but they are really designed for servo motor applications. there are better choices such as the Koyo encoders from Automation direct for Spindle encoder applications.
For a spindle encoder application, typically you want an enclosed encoder, one that doesn't require any additional environmental protection.
The Encoders Centroid sells are intended to be mounted on the end of a servo motor that has a water tight cover that protects the encoder. You could use them for a spindle encoder application you'd just have to protect the encoder from dust, grit, shavings, oil, water etc..

Re: encoder suitability
Encoder Products Company has big-bore encoders (up to 1.875") that work great on spindles.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

At approximately what cost? Say the 1.875" Differential, line driver output.tblough wrote: ↑Fri Oct 27, 2017 1:56 pm Encoder Products Company has big-bore encoders (up to 1.875") that work great on spindles.

It was around $650 for a 776-B-S-1024-R-HV-E-9D-A-Y-N

That's pretty slick but ouch on the price.

Re: encoder suitability
Hi Scot - I think I know what you are looking for. I'm working on a solution: I just put this on my G0765 mini-lathe but I haven't wired up the encoder - I'll do that tomorrow. I'm not sure how smooth the gears will run. This approach will work with pulleys, as well but it's just slightly more work to install. Lots of flexibility on encoder selection using this approach (I hope ) I'll let you know how I make out.

Re: encoder suitability
Hey Brad,
That's cool! Is that gear on the encoder an original part? Will be waiting to see what you come up with. I've been busy and have made some progress with my mini mill. The Acorn and all the electronics are finally almost done! Haven't had time yet to work on the lathe.

Re: encoder suitability
The encoder gear and the bracket are 3D printed ABS of my own design. The gear may work but I'm concerned about the vibrations. I may be moving to a pulley configuration if I see a problem.

Re: encoder suitability
I'm a little concerned about gear backlash....i think I would have purchased a large enough timing pulley to allow you to bore it out and clamp it to your spindle.
If some how you can adjust the backlash out, it may work...looking forward to seeing how it goes.

Re: encoder suitability
A pulley and belt are a better choice. I wanted to start with the gear as that can be a simple bolt on to the machine that doesn't require any disassembly. I'll be testing it out this evening. I'll let you know how it goes.
