Spindle Encoder

the line:
setp [HMOT](CARD0).encoder.04.counter-mode 0

shouldn't this be set to 1?

ah ok, no that would be bad.

Hello,

so there is good news i managed to set up the index signal manually and it also goes off when it hits the npn sensor.

on the one hand I have the spindle-pos-rowcounts. these always go the opposite way. is that normal? If I turn to +, they go to --. and the other way around.

However, I am still puzzled as to how I can get the whole thing added when the spindle turns.

My servo motor has 56 teeth and the spindle has 22 teeth. The encoder is on the servo while the npn sensor is on the spindle.

I checked the speed and it was correct when I calculated it. When the encoder resolution, I'm unsure.

step scale -10000

encoder scale -10000?

to the encoder of power 4x2500ppr

XXX The encoder scale should be 22/56*10000 = 3928.57 (counts per turn)

EDIT: Sorry the encoder scale should just be 10000 (or -10000 to get the direction correct)

The step scale only affects the spindle RPM scaling
(unless you need to orient the spindle)

ok but when will the controller release the index. I tested it manually.

LinuxCNC sets index enable when it starts a spindle synchronized move.
When the hardware detects the index, (and index enable is true) index enable
is set false, and the encoder position is cleared. Index enable going false
signals LinuxCNC to begin the spindle synchronized axis move.

So I can test it eg. with g33.1.

what is it like at the beginning of a program, until now the machine has always stopped, is the machine also waiting for the index there?

If you have gcode for a spindle synchronized move
you need:

spindle-at-speed true
index working
spindle running and encoder counting in the correct direction

before the synchronized motion will proceed

is that correct spindle-at-speed goes off when the spindle is turning and is active when the spindle is on? I noticed today on the Hal show



here is a small example
