I did something a bit like this using resolvers (with the difference being that resolvers are single-turn absolute)

wiki.linuxcnc.org/cgi-bin/wiki.pl?Psuedo-Absolute_Encoders

You probably need a realtime HAL component (or set of standard components) that zeros the absolute portion of your adder when the index is seen. This is because of the way that the joint position feedback is used in the home offset calcuations.

There is an example .comp here:

github.com/LinuxCNC/linuxcnc/blob/master...ivers/mesa_uart.comp

Or if the PktUART is a better fit (it probably is) have a look at:
github.com/LinuxCNC/linuxcnc/blob/master...sa_pktgyro_test.comp

This works for me:

 

Which user interface are you using? And which version of LinuxCNC?

#### generally means that the parameter doesn't exist, but that doesn't make any sense for #5181.

You are typing (debug, #5081) not (for example) (debug, #<5081>) ?

Here is now a modified cia402 component together with a complete example on how to use PV (Profile Velcotiy) for an EtherCAT spindle drive.

Hallo,

ich habe mit einem usb linuxcnc live den rechner gestartet.

dann linuxcnc damit neu installiert. mbr wurde auf der entsprechenden festplatte

neu installiert. nach fertigstellung, neu gestartet. mein Linuxcnc und die maschine laufen wieder.

It opens a blank site but should download a .zip file (or open a popup about downloading a zip file with all the source files).

This is what I get when I click on the link in your last post:
 

A Mesa webáruházban, ha a támogatásra kattintok, csak egy üres ablakot hoz fel.
(www.mesanet.com/software/parallel/7i92.zip) vagy bármilyen más.
Csak a letölthető PDF.
Or is it just me that the download from the MESA site doesn't work?
Ezért kérdezem, hogy hol érhető el még a teljes kód.

Just a hal component to take data from the UART and encoder channel then handle it

Okey, are you referring to make custom firmware/component for FPGA for UART + quadrature encoder logic or referring to hal component?

You would need the Xilinx tool chain (Webpack 14.7)  for a 7I92, 7I92H, 7I92M
 

@abs32
Please don't post the same questions in different threads.

CT identifies it as Mesa 7I92 and suggests corresponding files for upload.
I uploaded several files to it as a test. It works fine.
Test assembled on the table CNC program moves the motor + outputs and inputs work.

Hi,

I was wondering if any could give some insight on this one.  I tried to use the M6 subroutine that orangecat made.  I was able to get the probe working, change the ini and hal files accordingly.  I got to the point were the tool would probe, but my tool table won't populate with that number.  When I debug the 5063 in mdi I get ###### not an actual number, however the 5063 variable will show up in the var file in the config folder as a function of the 38.2 probing routine as an actual number.  I tried to debug other variables like 5181 which is the x position for the G30.1 command and although the var table in the config folder would populate with a number, when I debug the 5181 in mdi I still get #####.  I'm assuming the debug should yield the same number in the var file and not this symbol #####?  Which might be one of the reasons my tooltable is not populating?  I'm happy to provide any files, youtube videos, or anything else needed to help solve this problem.  I've learned a lot in the last month trying to solve this problem, any advice is much appreciated. 

Thank you in advance.  

Are you really using 2.8.4 rather than 2.9.4?

This problem was fixed in 2.9.5. Do you have a good reason not to update?

(rather than 2.9.5 you should probably use 2.9.7. See:
