Sorry I was thinking 7I88

Do you have the plug in correctly?
(the 6 pin 7I76e plug will work in the 7I89 if you skip the top pin = one pin above and below the 6 pin plug empty)

Also verify the the 7I89 has 5V power

Yes I think I have the plug in correctly. I can measure 5V between 7i89 TB3 Pin 17/23 and Pin 18/24.
The 7i89 also is connected to 5V at P1.
The 7i89 generally works if i connect an encoder to one of the encoder inputs.

The 7i76e jumpers W7 and W12 are in up position --> Pins 22, 23, 24 and 25 are 5V (required in 7i89 manual).
The 7i66-24 works connected directly to 7i76e via RS-422/485 SSerial.

The 7i66-24 doesn't work if i use the cable and pin configuration mentioned in 7i89 manual.
The 7i66-24 also doesn't work if I use the 6 pin 7I76e plug and cable and skip the top pin (= one pin above and below the 6 pin plug empty) although the cable worked between 7i76e - 7i70 and 7i76e - 7i89.

I added a picture of the bitfile readout (generated from you). Is there everything fine with the RS-422/485 SSerial configuration?

Do you have further ideas?

best regards

Uhhhhh I got a solution:
I opended the HAL Configuration and changed:
sserial_port_0=00XXXX to sserial_port_0=000XXX and it worked!

In the bitfile readout (I posted above) RXData2 / TXData2 is shown. So just for me to anderstand is this the third port (--> 0,1, 2) or how do I know which sserial port is used?

Yes, sserial_port_0=00XXXX only enables the first 2 sserial channels (0 and 1) on port 0
(and sets them both to mode 0)

This is described in the hostmot2 manual page

man hostmot2

The last few days I tried to realize a spindle synchronization and orientation for my mill, after replacing the damaged spindle encoder. I tried to adapt the HAL and INI content from Talla83 from this video: Link .

Basically I have a different card combination. I use the 7i76e card TB4 spindle connector (0-10VDC) + additional CW/CCW output for spindle direction. I connected my 2000ppr encoder to the high speed encoder input (10MHz) in differential (RS-422) mode with A/A-, B/B-, Z/Z-.
According to this the encoder scale in INI File should be 8000 (quadrature ecoder) right?

I also use the LinuxCNC 2.9 instad of the 2.7 from Talla83's video. I tried to adapt the code for my card and software combination. But It doesn't work . I always get the failure "spindle.1.orient-ange does not exist". Probably the "motion" doesn't work probably in my HAL file vonfiguration - I guess I forgot something....

I already read the LinuxCNC motion "manuel" but couldn't find the problem.

I attached the relevant part of ini and hal file to this post.
Would be great if you can help me =)

There are many corrupted pin names in your hal file, for example:

net orient-angle spindle.1.orient−angle => orient.0.angle

It looks like the hal file was edited with a word processor instead of a text editor
or some kind of character set bungle

EDIT:

Globally replacing "−" with "." _seems_ to fix things

Hey PCW,
thank you for your response. I guess something went before I uploaded the files. I opened the HAL file from origin with text editor and the corrupted pin names were gone. The basic problem still exists. I uploaded the files again.

Best regards
Oehli

Edit: Funny, if you open the files via text editor the failure is gone. Opened with windwos explore not.

Edit2: Luxmill_2020-05-25-2_V2.hal --> corrected.

Which text editor? I'm using gedit which shows the error

Thank you again. I fixed this mistake in the Hal file, but I'am sure I would have recognized this problem on mylinux machine. I'll check tomorrow.
According to your opinion the "motion" configuratio in my Hal file is correct or is there something missing?
