Spindle encoder connections

Good morning,

I am having issues trying to get the spindle encoder working with Pathpilot. My set up is 5i25 and 7i76.
The spindle encoder I'm using is a 1024 p/r quadrature encoder. I have the wiring set up as per instructions and have it connected to the right pins in the 7i76 board. I have changed the pins on the hal file but i am going no where.

Can anyone see if they can help me get this running.

I am attaching my files.

Let me elaborate a little more.

I have encoder wired as follows on TB3 connector for spindle encoder
Pin 7 ENCA+
Pin 10 ENCB+
Pin 9 GND
Pin 12 +5v

A couple of things:

Is the 7I76 jumpered for single ended encoder inputs?
Does your encoder have an index connection? (rigid tapping and threading require this)

I have looked all over the manual for the jumper setting on the encoder and I don't see it. Do you know what jumper it is and what position it has to be?

The encoder has index connections for A,B Z

Bottom of page 2 :ENCODER INPUT MODE

Z must be connected for rigid tapping and threading

Ok I think i need glasses! Thank you for pointing me to the right page.

Where would i connect the Z to?

Z connect to the IDX+ pin (IDX is an abbreviation of Index)

PCW,

Thank you. Its working but once i go over 1200 rpm tracking drops on the encoder.
I have a 1024 quadrature encoder. pulley ratio is 1:1 max rpm's is 6000
in the ini file i have the Spindle 9 settings as
Encoder scale = 4096
output scale;e = 4096
output min limit =-4096
output max limit = 4096

Im sure the is something incorrect here but don't know what it is.

Any ideas?

Thanks again,
Raul

I have a Mesa 7i76. setting at 10, -10, 10 does not work. makes the spindle spin at full rpm.

The settings that Torch had are 2930, -2930, 2930. with these numbers the spindle does not spin at full RPM. But I am still having issues with the encoder as Pathpilot drops tracking the spindle over 1200 rpm.
