UGS wont connect under FluidNC drop down

[itsnotlevel1]

Version

2.1.8

Hardware / Firmware

FluidNC

What happened

UGS Wont connect to machine using the FluidNC drop down, it keeps telling me...
*** Fetching device settings
*** Could not establish connection with the controller
*** Connection closed
*** Could not establish connection with the controller

But when I choose grbl esp32 from the drop down, it connects and runs fine. Runs a job if I load it.
I tried everything thinking it was a hardware issue, its not a hardware issue that I can see.

How to reproduce

If I choose FluidNC from drop down, it will not connect and gives the same response. But grbl esp32 connects every time and works with the machine.

Operating System

Windows 11 Pro

Anything else

Every time.

What is the output of $I?

Worked just fine for me:

What is the controller state after you connected using the GRBL_ESP32 profile?

Can you disconnect, enable verbose logging (right click in console and select "Enable verbose logging") and connect again with the FluidNC profile and paste the messages here.

Can you attach your config.yaml.

[itsnotlevel1]

After Connecting to grblesp32 profile, the machine and controller are ready to be used. Ive run a program with it.

Heres the output of Fluidnc connection profile:

I loaded up your config to a controller and tried it. I don't have TMC drivers or the Huangyang spindle so I am not able to simulate your scenario fully.

But I think that this is a clue:

It looks like the controller has not completed the boot before UGS starts quering the controller. Can you connect and power up your controller and wait a minute before connecting to the controller through UGS. This should not be a problem, but looking through the lines after there are some wierd things happening.

The reason it fails to connect later on looks to be caused by it either getting duplicated messages from the controller . Here is an example, it receives the line with 180: Parameter Assignment Failed and then an ok. But these two lines is later repeated.

175: Expression Syntax Error
176: Flow Control Syntax Error
177: Flow Control Not Executing Macro
178: Flow Control Out of Memory
179: Flow Control Stack Overflow

So, I did what you asked and still nothing. Then I unplugged my vfd and it connected but nothing has changed unless for some reason theres a variable in the huanyang vfd I need to change? I havent changed anything. I unplugged and reconnected several times....it works now. But if I plug the spindle in, it wont connect.
And as it should, when spindle unplugged it gives me this: INFO: VFD RS485 Unresponsive but thats typical.

I noticed these two lines though when you connected to it using the GRBL profile and remember that there was another issue where UGS would try to initiate the connection twice on certain device setups (think it was when connecting to it via WiFi):

I fixed that particular issue in version 2.1.9, you could give that version a try:
https://github.com/winder/Universal-G-Code-Sender/releases/tag/v2.1.9

Other than that this will be really hard for me to debug and fix as I don't have a controller equipped with RS485 and VFD supporting it.

Sorry for the late reply, another user had the same problem and I think that I've fixed it.
