UGS

What happened?

I am using platform.io to compile fluid nc, when i try to connect ugs using fluidnc the ugs give this error
(*** Expected a 'FluidNC 3.3.0' or later but got 'FluidNC 3.0.0'
*** Could not establish connection with the controller
*** Connection close)

& i am using v3.6.5 of fluid nc i jut dont know how to change this line of startup messege from code. here is the line.
$ss
[MSG:INFO: FluidNC v3.0.x (noGit)]

with grbl normal it is working but the only problem is homing button is not working with grbl selection .

Hello . In the file git-version.py in line 13 + 23 simply enter the new version v3.7.4 then it works with UGS as well. Recompile.

Hi @BlueOrangeLive

i change that line now ugs connect to fluid nc but there is one problem with normal grbl selection A Rotary axis works well but when i select fluid nc taht a axis is gone i share some screenshots here.

with normal grbl selection

with fluid nc

i use same board and config file.

Another way to change the version number in the startup message is with $start/message http://wiki.fluidnc.com/en/features/commands_and_settings#settings

[breiler]

We are looking into the problem.

UGS uses the $Config/Dump to determine which axes are available. But it can't currently not parse the response of the command as FluidNC doesn't seem to finish the response with an "ok" anymore.

We could probably fix this in UGS to detect the axis using the status response instead. But I would like to use the $Config/Dump command for other purposes, so this needs to be fixed anyway.

[breiler]

Ok, the error was in UGS and was introduced when I consolidated GRBL stuff with FluidNC.

I have fixed this in winder/Universal-G-Code-Sender#2260 and should be available in the latest nightly build here: https://github.com/winder/Universal-G-Code-Sender#downloads

Thanks @breiler

I close this issue here & wait for new release of ugs.

Again thank you so much for your help.
