General Mach Discussion / Re: Spindle speed not correcting spindle speed with ESS and C23 board

There is a long running topic on threading which I do not believe has ever been resolved.

It is not a mach3 issue.

Mach4 will not bring any of the more complex features yet from the looks of things... My advice if you are in an industrial environment and time is money stick with machmach 3 for the moment given way more people know about it and asking a question will bring 10 armchair experts (me one of them) and three Yoda's.

Cismo has a threading module but you need the controller first have a look at their site.

What vfd are you using?

Is there a manufacturer and a model number?

Need a wiring diagram really...

Looking at the encoder manual you are going to have a problem using it:
http://www.adafruit.com/datasheets/pec11.pdf

If you look at the first section: electrical charactoristics, current rating = 1mA @ 5V

Looking at your C32 board all of the limit switches and probe inputs have a pullup resistor (basically a resistor that connects between 5V and the connected pin, so that the switch grounds the input pin)
http://cnc4pc.com/Tech_Docs/C32R5%204_USER_MANUAL.pdf

The problem comes from the input arrangement where (yup this is very common across bobs) the optoisolator input is an LED... and they require a certain current to function which looking at the pullup resistor ratings in your manual is somewhere around:
19mA for the probe input  (5v - ~1.2V) / 200 ohm = 19mA
23mA for a 12V prox input (12v - ~1.2) / 4700 ohm = 23mA
5mA for a 24v prox input (24v - ~1.2v) / 4700 ohm = 5mA

and your encoder is only rated at 1mA...

I cannot tell what chips they have used with the C32 to provide the optoisolated inputs but if you can workout which chips deal with the inputs you can find the datasheets and see what their current requirements are for the LED to operate (there are some high speed switching optoisolators that use very little current too)

If you look at this diagram, you can see that the encoder is what I thought it was .... Just two switches, each one makes and breaks to ground

https://learn.adafruit.com/trinket-usb-volume-knob/wiring

So connect a 0v/ ground from your bob to the ground connection

And then connect one pin of your bob to an a and one pin to the b connection exactly the same way your bob manual shows you to wire up a switch.

Is this your encoder?

Yup that is how it is setup.

What happens if you change the ratio to 1.5?

The last item ... Does this not provide a calibration for the DRO
Finally go to Mach3's Menu -> Config -> Spindle Pulleys

 Choose a pulley
Choose a min and max RPM so that the spindle feedback can calculate the correct RPM for display
