General Mach Discussion / Re: CNC Lathe conversion with threading

Hi Hood,
Thanks for the reply.
For your info i am doing a Tech course based on cnc machine control and my husband and i thought the best way to learn is for me to build some and use them. I have a bench top mill and router which i converted, so i have gained some experience.
For the lathe i am converting i want screw cutting.
I was going to use cnc4pc, C3 board for index pulse, i have one left over from when i converted my bench top mill. Would this be suitable with ETSS.
I want to use full spindle control i have a dual relay board.
I think my biggest problem is what i cant get my head around is how to control spindle speed, the control board that comes within the lathe works on 0-5 Vdc for the Pot.
How can i use the 5 Vdc reference voltage with ETSS to give speed control or will i need another board from somewhere to do this?
Best wishes,
Cheryl
