Spindle speed variation ssv for chatter control

Steady up Andy, you'll have poor old Robert's head spinning!

But it is an interesting concept to explore... If you tried them all, you would learn a lot about Linuxcnc.

Thanks Gents

Not too many options please, head is already spinning and I am just starting out. Give it 6-12m and maybe I'll get to advance to the next class.

(too many options in Linux (not just the cnc bit) that becomes overwhelming to new users, yes I know it's flexibility and options.... sometimes just learning the basics is useful [I only learnt to use TAB in terminal to auto fill in the file names a month ago + '&' to start an instance using the same terminal window....... {I just can't remember how you start multiple instances from 1 terminal {something like '&6' but it didn't like that when I tried it}) All new stuff and good stuff to learn.

(I'd like to get into components but its baby steps + need, LCNC has so many options / components already, I can't think of something I need that doesn't already exist {yet})

I'd also be up for this..

all details on the page before

I have already assign spindle-pwm pin
net spindle-pwm => parport.0.pin-01-out
Should I uncomment this and assign to
net mod_spindle_speed => parport.0.pin-01-out
will this work?

No, you would alter the source of the _input_ to the PWM generator to be the mod_spindle_speed. 

Look for the line which contains pwmgen.0.value.
