[Grbl_Esp32 Issue#213] No Configuration Panel

#1 – bdring 于 2019-09-10

Send a screen shot showing the panel.

Did you click the refresh icon? Open a serial terminal and send $$ plus carriage return to the the ESP32. Do you get a response?

#2 – NickHead 于 2019-09-10

Tried everything. Even re-flashed quite a few times after re-compiling. It just shows Value,Name and Help but nothing underneath.
If I do a $$ in the console, the GRBL configuration shows, but not on the html page. I am at a dead loss

#3 – bdring 于 2019-09-10

I look into it. Maybe a recent change broke something.

#4 – luc-github 于 2019-09-10

I have just downloaded and tested master and it is fine :

#5 – luc-github 于 2019-09-10

@NickHead what version do you use?

#6 – bdring 于 2019-09-10

Are you connected to hardware or is this a loose ESP32?

#7 – bdring 于 2019-09-10

This is just a guess, but the default configuration is for the controller shown on the readme page. It uses some I/O that requires pullup resistors. If those pins float, it could put the controller into a locked mode.

Try uncommenting #define IGNORECONTROLPINS in config.h and recompiling the firmware.

#8 – NickHead 于 2019-09-10

Sorry about not replying fast, I am in the middle of a multitude of things.
Thanks for all the replies though, it’s really appreciated>
I downloaded the latest version of GRBLESP.
It’s running on an ESP32 WROOM .
It is not connected to any hardware, just the micro, by itself. I never thought it would make a difference.
I will try the ignore control as soon as I can and report back.
Regards.

[E][Parsing.cpp:82] _parseRequest(): Invalid request: ␖␃␁
[E][WebServer.cpp:602] _handleRequest(): request handler not found
[E][WiFiClient.cpp:365] write(): fail on fd 61, errno: 104, “Connection reset by peer”

That did not work either, I may try a compile on a different computer and see what happens

Does the rest of the WebUI appear to work? I could send a firmware to load via OTA update.

#12 – NickHead 于 2019-09-10

Yes, the rest does look OK , the controller shows values X,Y positions. It’s just the GRBL config I am having issues with and to be fair, I don’t know if I am doing anything wrong.

#13 – bdring 于 2019-09-10

Here is a compressed .bin file that works for me. Unzip it and use the yellow cloud icon on the ESP3D page to upload the .bin file.

I am out for a few hours, but can check in later.

#14 – NickHead 于 2019-09-11

Something must be wrong. Unzipped, pressed yellow cloud, accepted to update, came back with an error 0.
I am no novice to all this either , so you can be assured I know what I am doing to an extent.
Unless I have a defective ESP , I may have to see if I have any more laying about.

#15 – luc-github 于 2019-09-11

back to basic – what version do you use ?
Check the screen I sent before on top of menu, it have the versions on it, do a screenshot
!image

also :
what OS / browser do you use ?
what version of esp 32 core do you use ?
you can do a screenshot of window that apear when pushing blue button :

#16 – NickHead 于 2019-09-11

Hi luc
Cant do a screen shot as it’s running on a separate laptop.
Best I can do is:
UI:2 1b50 / FW: 1.1f
(20190905)

#17 – luc-github 于 2019-09-11

this is not the master branch, you use the latest version of webUI which is not validated yet with GRBL
please use the index.html.gz that is present in your grbl_esp32 fw directory in data directory

Every version of webUI provided with FW are working – the others may have issue

I can reproduce your issue now I have the information – I will work on it

#18 – NickHead 于 2019-09-11

Right, thanks, that may be where I am going wrong as I did download the index gz file externally, it was mentioned to do that in some random setup website that I read
Hopefully it will work.

#19 – luc-github 于 2019-09-11

let me know if not – we can continue to dig in issue

Edit: I fixed it in WebUI repository – thank you for reporting it ^_^

#20 – NickHead 于 2019-09-11

Thanks luc.
After a problem getting the wifi to work (I used arduino libraries in the compiler and it didn’t like it for some reason) I have managed to get the configuration html up by sending over the correct file from the directory.
I do have an error though, but I can live with this for now.
I have always had this error from the very beginning, but won’t bother you anymore (for now )

[E][WebServer.cpp:602] _handleRequest(): request handler not found

Just for information.

Many thanks for the help, let the fun begin.

Regards.

#21 – luc-github 于 2019-09-11

well this part is not normal and it is in FW
can you screenshot the content of blue button ?

#22 – NickHead 于 2019-09-11

When I do a refresh of the main page (F5) I get this:
[E][WebServer.cpp:602] _handleRequest(): request handler not found
[E][Parsing.cpp:275] _parseArguments(): arg missing value: 0
[E][WebServer.cpp:602] _handleRequest(): request handler not found
[E][Parsing.cpp:275] _parseArguments(): arg missing value: 0
[E][WebServer.cpp:602] _handleRequest(): request handler not found

#23 – NickHead 于 2019-09-11

this is monitoring on the terminal of the compiler
Not on the screen on the html page

#24 – luc-github 于 2019-09-11

yes – but I need info on what core and configuration you are – so I need what info show in info window of blue button

Because on my side I cannot reproduce your issue

#25 – NickHead 于 2019-09-11

UI: 2.1b39 / FW: 1.1f

I cant capture the screen as I am on a different laptop and it is on a different IP, the config from the info is above if that is any use

#26 – NickHead 于 2019-09-11

I managed a version to send
!GRBL32

#27 – luc-github 于 2019-09-11

no, what I need is the display of this blue button :
!image

#28 – NickHead 于 2019-09-11

ok, sorry there were too many blue buttons to contend with, 2 secs

#29 – luc-github 于 2019-09-11

because what you show it is an old version – so I am quite sure the problem is not in FW but in the way you build it so I need to know the esp32 core version
