To power the 7I85 from the 7I97T, you must also change
the 7I97T cable power jumper (W22 must be up)

Did you check if the sserial port is enabled in your hal file?
(you have the cable connected to what is sserial port 2
on the 7I85) so you need at least sserial_port_0=ABCxxxxx
where C is the mode for sserial channel  2
 

First question.
Why do you use stm?

Have you considered using Modbus RTU?

Some thoughts.

As for getting data to/from your STM, here is a project using STM, that may (or may not) give you some ideas:
github.com/scottalford75/Remora

Also with the 'external offset' feature you could move your Z axis without using Gcode but entirely from HAL.
linuxcnc.org/docs/stable/html/motion/external-offsets.html

Ok so my  parts arrived and I connected everything.
 p
However, the setup is not working currently. When I have the jumper on the 7i85 set to get 5v from the db25 cable it does not get power. Powering it from my 5v supply with the jumper correctly positioned it turns on and gives power through the cat5 cable to the 7i73 but no communication takes place.
This leads me to believe my bitfile on the 7i97t is wrong or not working properly.
Once again the smart serial port on the 7i97 itself works correctly and plugging the 7i73 into that shows it in the terminal using mesaflash so the problem is likely the pinout on the expansion port on the 7i97t?

Can someone help me out?

Have a look over here:
forum.linuxcnc.org/10-advanced-configura...hange-problem#310069

I have no problem helping you, BUT you must describe what you exactly need:
- we need wiring diagrams (or description electronic)
- your current LCNC configuration
- description of machine/ATC function
- photos of the machine would help

Hello!

I'm struggling here... in my case there is no such folder as config...

I'm going to make a Scara arm so I don't know if it can have several configurations or just 1... because I haven't run my servo on Ethercat yet and I want to continue to get it either way. Then I'll go where I need to go.
Question 1: Is this config folder generated after I open Linux CNC? I don't want to do that because I'm once again faithfully following the tutorial that's on the forum. Hehehehe
Question 2: If I make it for a 3-axis CNC router, can I make a configuration for Scara and will the Ethercat issue be the same?

Thankyou
I send "z_up" with stm with serial and in exact moment I need z axis to go up
i really don't understand what you saying
can you help me please?

Python does not run in real time so for timing critical things a python remap is not really what you want to use in the first place. You would be much better off using a compiled real time component (ie .c or .comp) that could export stm state as hal pins.

Establishing Ethercat communication is covered beautifully by forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step 

But for those like me who struggle with following instructions you might encounter the following error
 
because you failed to modify the ethercat conf file located 
with

MASTER0_DEVICE="xx:aa:yy:zz:bb:cc"DEVICE_MODULES="generic"

 

beware that is might not show an error like this if you missed the  DEVICE_MODULES="generic" line further down the file. but it did not behave as expected / work. 

the end result of   "sudo systemctl status ethercat.service" should look like this
 

To confirm that Ethercat is trying to do something, but without any slave devices attached the command " ethercat master" should provide some conformation that something is going on. the output of the command should appear something like this.
 





 

Mostly 3D printed jet pump. Still refining the design.

I appreciate your attention
I send "z_up" with stm with serial and in exact moment I need z axis to go up
I'm confused how I'm supposed to do it based on your statement.
It's likely because I'm a novice so Please be considerate and lend me a hand.
