Mesa 5i25 and 7i76 and encoder was created by finemeca
Hello

With a mesa 5i25 and 7i76 where connect the Z+ and Z- Phase?

In the doc is indicated for the TB3:

7 ENCA+ --> phase A+
8 ENCA- --> phase A-
9 GND
10 ENCB+ --> phase B+
11 ENCB- --> phase B-
12 +5VP

Index Z+ ??????????
Index Z- ??????????

Best regards,

Pierre

7I76 OPERATION
ENCODER INTERFACE
The 7I76 provide a one channel encoder interface with index.
This is intended as a spindle encoder but can be used for other purposes. The encoder input can beprogrammed for differential or single ended encoders.
The encoder interface also provides short circuit protected 5V power to the encoder. When used with single ended encoders, the ENCA+, ENCB+ and IDX+ signals are wired to the encoder and the ENCA-,ENCB-, and IDX- terminal left unconnected.


so it will be on the idx pins.

OK thanks.

And in the hal file

What should I add to the mesa cards?

With a parallel port I put:

loadrt encoder num_chan=1
addf encoder.update-counters base-thread
addf encoder.capture-position servo-thread
setp encoder.0.position-scale 100
setp encoder.0.counter-mode 1
net spindle-position encoder.0.position => motion.spindle-revs
net spindle-velocity encoder.0.velocity => motion.spindle-speed-in
net spindle-index-enable encoder.0.index-enable <=> motion.spindle-index-enable
net spindle-phase-a encoder.0.phase-A
net spindle-phase-b encoder.0.phase-B
net spindle-index encoder.0.phase-Z
net spindle-phase-a <= parport.0.pin-10-in
net spindle-index <= parport.0.pin-11-in

open "show hal configuration" and search for the 7i76 encoder pins. you should have position and velocity output pins.

With open "show hal configuration", i have good phase A, phase B and phase Z

A gcode with :
G96 D1700 S80 M3
G95 F0.2
G1 z-100

I have no movement with :
G1 z-100

I think that something is missing in my Hal file:

I'll look tomorrow with the Hal meter if the variable is set to true

what are you trying to do in first place? the encoder is to to spindle or to the Z axis? why you need to use index ?

Yes the encoder is on the spindle.
It is a lathe.
Phase Z+ is that of the encoder with Z-, A+, A-, B+, B-

The phase Z is idx pins

to use constant surface speed, like PCW said you need motion.spindle-at-speed true when the spindle rpm's match the requested rpm's.
