Lathe Macros

I have isolated digital potentiometer intended for spindle control at my store.

Thanks Andy and JT,

I have a spindle encoder already installed and working. I was just dry running the controller away from the machine, getting to know it.

Hello everyone, I am new to the forum, I am Spanish and I have to translate to speak here, to thank the people who do these jobs are very good.
I read a lot of information these last weeks to motorize my around with linux cnc and it seems that I managed to move with a TB6560 and two step-step motors card, yet not I have encoder for the spindle but I'm starting. I linuxcc 2.7.0 and I installed lathemacros3 as I read in the download but when pressed the play and accept the tool lathe makes the first political movement and then stays in play but not continuous, took several days and do not get a solution my level of programming is very low, someone could help me, thank you very much, have if you understand me with this translation,

If you don't have a spindle encoder then you will need to edit the G-code routines to not use Constant Surface Speed or Feed-per-revolution G-codes. And you will not be able to thread.
But that's just G-code, and you need to learn that to do CNC

Might want to look here...
forum.linuxcnc.org/forum/lathe-subroutines-library
Some of the subs such as
forum.linuxcnc.org/forum/lathe-subroutin...26977-odtaper-lathe3
Do not use constant surface speed so may run for you and serve as a starting point.
