Replacing a Potentiometer on a DC Motor Speed Controller

[ScotY]

In a perfect world, I'd like to be able to use the Acorn relays to turn the spindle off/on and control the direction. I would be extremely appreciative if you could make a video explaining what to buy and how to hook it up. That would be awesome!

Yes, I second that!

If you want DC you have to add the board Marty is talking about. I just went down this road. (I have a KBMG with the isolation board for sale, lol) I want to keep everything off the shelf.
AC with an inverter is the absolute simplest solution for a spindle drive. Easy to hook up, reverse, brake, etc. AND cheap these days. Acorn can do it now.

For me it isn't a good solution as I want a single motor for my C axis and my lathe spindle.

Hi Clay,
Can you create a post on how to do this and what motor/drive combination (and how to wire it up) might do well on a mini mill or lathe. 1 HP would be more than adequate. I’m still trying to decide what route to take with this. For my mini lathe, I’d prefer to stick with the stock motor and add on whatever electronics would be needed to control it. For the mill, I would prefer to replace with something else.
Thanks, Scot

For clarification I chose not to go the DC reversing route. I'm going AC servo.
If you want to go that route, Marty is a MUCH better source as he has info on the board/circuit necessary to do this.

If you want to go the easiest route, which is an AC inverter and 3 phase motor, there is a ton of information already out there in the schematics, and the youtube.
