Please start linuxcnc from the command line and check the output there. 
You will see there the error that does stop your panel to be embedded.

Replied by kello711 on topic 7i96S card arrived what setup is recomended

7I96S    CL57
+5V     PUL+
STEP-   PUL-
+5V     DIR+
DIR-     DIR-

SW3 Set for 5V mode

The ENA, ALM and BRK can be left unconnected
I have a similar setup I'm building. If I wanted to use the ENA and ALM as well as STEP/DIR, which position should the S3 switch be in 5V or 24V? I know the 7i96S provides 5V power for STEP/DIR but my field power is 24V. Can I do this or would I need to provide a separate 5V power source for my ENA/ALM signals?

Is the "unplug and plug" thing correct, meaning is it the same pinout for SSerial on 7i96S and 7i85?
Sorry if i messed that up, i never used a 7i85, yet, it was just an educated guess from experience with Mesa boards and very consistent pinout.

Pico Universal PWM Won't boot Random pins not working was created by LearningLinuxCNC
So I have not used my RB1-CNC machine for a while. I tried starting it up today and I am getting errors on load that have to do with not being able to find pins on the Pico Systems Universal PWM board. Sometimes it won't find the board at all other times it won't find an generic IO pin other times it won't find an encoder pin.

This was working then I had to reconfigure from 2.7 to 2.8 and got it working again and now after setting for around a year I can't get it to load into linuxcnc unless I comment out of the hal files that tie to the pins on the UPWM board.

Here is one of the error outputs.

tommylights suggestion is on the right track,
Modbus needs RS-485 and the 7I85 serial interfaces
are RS-422 only (no TXEN).

What if you connect the 7i84 to the 7i85 and use the 7i96S SSerial for PktUART ?
Just an idea as wiring the 7i84 to 7i85 works without any setup and requires simple unplug from 7i96S and plug to 7i85, but also editing the hal to change the SSerial card channel.
Edit:
See below about SSerial on 7i96S and 7i85

Replied by Muzzer on topic Updating from LINUXCNC - 2.8.4-23, Mint 20.3 - gmoccapy lathe structure
Anyway, back to the problem in hand. When I run my installation, I'm getting a lot of missing content in the "cycles" tab:
 

And the command line errors currently look like the contents in the attached text file.
 

File Attachment:

File Name: gmoccapy_errors.txt
File Size:3.15 KB

It looks as if there is something seriously wrong in the Gtk / python / gladevcp bit. Could somebody suggest how I might troubleshoot / resolve these errors?
LinuxCNC seems to run OK but the macros are still not showing up. Many thanks.

Linuxcnc 2.9.x and Glade GTK3 display issue was created by mmt
Just upgraded to 2.9.x from 2.7.x i am in the process of recreating my glade window with gtk3. All worked good in 2.7.x and gtk2 but now with 2.9.x and gtk3 this code below in my ini file deletes the the box_vel_info but does not start the motion_control_test.ui
not sure what is going on. help is appreciated

EMBED_TAB_NAME = MOTION CONTROL
EMBED_TAB_LOCATION = box_vel_info
EMBED_TAB_COMMAND = gladevcp -x {XID} motion_control_test.ui

Replied by scotta on topic Remora 1.1.0 + BTT Octopus – jog overshoot and joint following error
Hi, remora-1.1.0 is now over 4 years old. Please try the main branch which will give you the latest remora-spi component.

That's a very slow SPI frequency and is probably taking longer than a servo thread to send the full packet, hence the lag.

I'd suggest working on your noise issue to improve it as much as possible so that you can increase the SPI frequency. An occasional "bad SPI payload" is not a show stopper.

Wow! Lots of replies that I was hoping to receive an email about. >.> 

I'll admit, Arduino would absolutely be a better platform for this, considering the timing overhead of running the entire Linux kernal for the sake of a single stepper motor. That being said, (and at the risk of falling prey to sunk cost) I'd really like to use this as a jumping off point to using LinuxCNC for other stuff down the line. Also, I've got the Pi in hand, whereas I'll have to order an Uno clone to pivot on hardware. 

I'm also hoping to make the solution a black box that presents a web interface advertised to `turntable.local`, so that my uncle can control the thing from any device on the LAN. I'm pivoting from using the desktop interface because he's hoping to use a tablet to control the turntable. (Personally I think a touchscreen would be KISS, but I'm not going to argue with the 'customer'.)

Or enter G0 X-40 in the MDI for it to go to -40 degrees.

G0, huh? I think that might be my ticket in under the hood, assuming I can get the HAL config all figured out. I'm going to give that a go before I make another topic asking for help adapting a `STEPCONF` output.

Can confirm: Rob fixed two issues that I had with the images before I even reported them. Don't be like me, folks, check to make sure the issue is still an issue in the latest image BEFORE you report it.

1. USB-LAN adapters should not be used on production machines, USB has inherent latency issues
2. from your explanation it seems like interference issues, so is the machine and PC properly grounded?

Error finishing read! Mesa 7i76e was created by DerKlotz
Hello,
I get the error mentioned when a milling operation has run to completion or when I stop an operation with the stop button.
I have attached some pictures. My Mesa card is connected to a USB-LAN adapter.
Thank you very much for your help.

I just switched MESA connection from the USB-LAN adapter to the intern LAN adapter and the error is gone... the reason i didn´t take the intern LAN was my post monthś ago forum.linuxcnc.org/9-installing-linuxcnc...to-connect-to-github but now it also works.
