User Interface Software

WebUI, FluidTerm

What happened?

Hi everyone,
I just received the hardware and started to set it up :

Downloaded [3.7.13] released, then installed install-wifi.bat
I opened FluidTerm
Import a "basic" yaml (provided on the Git of the ROOT CONTROLLER ISO : https://github.com/RootCNC/Root-Controller-ISO), code above, name : Root_4_Base.yaml
Connected to local network by wifi SSID:Car&D, connection seems ok
When trying to use WebUI, following message appears : "Failed to communicate with FW!"

When I try to open the ESP IP in the browser , the WebUI request is written in the FluidTerm console

I already try to install the [3.7.14-webui3-test] version, same problem

Can you help please?

I tried to reproduce your problem and everything worked. Here are the steps I followed:

1. Ran erase.bat in the installer package by double-clicking (this step is probably not necessary; I did it just to be sure I started from a clean slate)
2. Ran install-wifi.bat then closed the FluidTerm window
3. Ran install-fs.bat
4. Used FluidTerm Ctrl-U to upload Root_4_Base.yaml
5. Typed "$config/filename=Root_4_Base.yaml" in FluidTerm
6. Typed Ctrl-R in FluidTerm to reboot the ESP32 with the new YAML file
7. Found the IP address in the startup messages and browsed to that IP address. WebUI ran as expected

The only thing I can think of is that maybe your hardware already had a filesystem installed and it already had an old copy of index.html.gz that is incompatible with newer versions of FluidNC. You did not mention running install-fs.bat or otherwise uploading index.html.gz, so that hypothesis is plausible. I have no idea what Root controller hardware has preinstalled.

Did you try asking the people who took your money? Presumably the purchase entitles you to some support.

[MitchBradley]

The configuration file that you used refers to a spindle type "SiemensV20" that official FluidNC releases do not support. Perhaps the Root Controller folks maintain a special version that does support that spindle. That unsupported spindle is the cause of the "MSG:ERR" lines in the startup log.

The other config files in the Root Controller repo seem to use supported spindles like Huanyang and pwm.

Support is offered through email (root@rootcnc.com) or via discord (https://discord.gg/93Ue5SwthW)

You must upload FluidNC/data/index.html.gz into root motherboard
