Please help me Oo.
Thanks in advance

In AP mode - not every computer see the AP and the ones which see the AP have hard time to connect

if printer is in busy loop that take more than 3s ( like homing) ESP considers data out of date and switch off the temperature UI and display processing, which is initially to prepare data only not for printer busy
Would be better to always display even no data refresh, and use the timer to display a status: printer online or printer busy

Need to show hide IP/GW/mask according to IP mode selection
Need an animation and a refresh when restarting module for changes

Add a configurable polling time may help to adjust the loading of the requests, currently it is 2 s but may be 3s to 5s is enough

Can be added in System tab

but need to define first for what app - seems octodroid has a repo but it is not very active https://github.com/mariogrip/octodroid

or I code client myself

Home menu is always selected even when it is not current page, active flag is not set properly for pages others than home

I cannot use AP mode anymore - need to disable CSS to get display when it was working before - no idea where this come from - I tried http://arduino.esp8266.com/versions/1.6.5-1084-ga39ce29/package_esp8266com_index.json and it is working

As I am rewriting UI using template engine and SPIFFS this will decrease usage of PROGMEM and string manipulation
Page will also be created and send part by parts to avoid usage of whole memory for the page - instead of creating a 8K page then cut it to be send by 2k parts - I will create 2k then send - then continue to redo 2K then send, etc... so page will not be complete in memory and so won't have any size limitation.

just display issue, no functionnal impact, this due to string parsing is not properly buffered and use splited string after conversion to integer

module should be able to be configured by serial if no available wifi client
back bone is ready, [ESPxxx] is the template where xxx is command number and are the parameters
need to define what command are useful :
status
set ap/station mode (done) [ESP103]APP or [ESP103]STA
set SSID/password (done)[ESP100] and [ESP101]
set PHY mode
set authentification mode
set channel
set IP/GW/subnet
Get mode (ap/sta)
Get SSID
Get IP/GW/subnet IP done: [ESP111]
Get connection status
Restart [ESP888]RESTART
Reset Config [ESP444]RESET
Write Config [ESP444]CONFIG

$!? are converted to %2C%.... for the request but not decoded

need to implement urldecode2 from https://gist.github.com/jmsaavedra/7964251

First tests show it is fine using it - it decode properly - this is mandatory for password

Thanks for a very good project 👍 and thanks for sharing it.

When I applay a page, and there is a EPS8266.restart(), it will not boot up again. There is no debug messages (which at first start up) and there will be no life in the wireless network (ESP8266).

Do I something wrong, I use a NodeMCU 1.0

Best regards
Per

currently one big string is used to store the whole page which is used by send function which will cut the string in part because sending is limited to a size under 4K

so we can have 2x the size of the page a once which can lead to out of memory
the best is to add the page content until buffer is full then send - then refill the the buffer and purge the buffer at the end.
the issue is the content-length is not defined but browser will display page anyway and cut connection after 2s so should be ok

To be able to change hostname from configuration web page (system page) and use same for bonjour protocol
currently : ESP+mac number for hostname and esp8266.local for bonjour

better to be able to customize use same for both

even size is actually 48K seems creation failed but if size is 32 K it is OK
I have open a ticket to ask if there are some limitation at ESP 512/64K as NodeMcu 1M is fine
github.com/esp8266/Arduino/issues/894

when heating temperatures are send automatically so no need to request M105 as it may overload communications.
check time out for last temperature update would avoid this

need to define features:
current test code is able to get temperatures from M105 command, every second, but no UI is defined, plan to use some svg images to enhance UI
front end should allow to:
check printer status
edit eeprom?
pause/stop print
restart printer
list SD content
start a print using SD file ?
control temperature ?
change speed ？
jog axis ?

advanced:
send email is issue detected? print is done?

any comment suggestion is welcome

as mDNS does not work in AP mode

to avoid to flash for ui configuration

because of download of embedded css when module restart and it is delivering css - page do not display on client.

I use it from now but - feedback/suggestion of improvement are always welcome

Display IP or status at startup just sending M117 command

to get some fancy ico

SSDP responder is available - just need to add it for windows

compiled without change anything in source give error
after try with change ip, name etc nothing to do and print "Error Wifi AP! M117 192.168.0.1"

i think not initialize esp to ap mode
my version of esp8266 is 01
http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family#esp-01
arduino version 1.6.5

esp compiled with other source working
for example this is ok and esp go to ap mode

Basic UI is done / back end is ready - but I am not a designer anyone want to improve or have suggestion - please feel free

seems to be an SDK issue - so will enable mDNS only on station Mode to save loop time

if connected to internet - better to limit access with a password or hashkey to avoid anyone to reset printer when online

program works at 250.000 baud, no problem to connect
stability is ok with good power supply
first problem detected: printer status not update and remain stopped if you use browser update (chrome browser)
For restart connection to printer you need to select "station configuration" and reconnect to "printer status"
i suggest to add this options for productive use:

• movement icons: home buttom for axis, up/down and left/right at step of 1mm and 10mm (i think easy to add this options)
• real time temperature control
• stop/pause/restart button
• sd_memory: upload, delete and select file to print
• feed speed direct control

advanced option:

• use low price I2C webcam as Ov7670 for direct printing remote monitoring

professional option:

• 3d model preview :)

Hi,

id souccessfully flashed the ESP and id got it connected with the DaVinci.
But it cant connect to the printer because the printer do not answer.
Id also checked if id miss cabled RX/RX or TX/TX, there is no communication.
The ESP sends a lot of gcode to the printer, but it dont get any answer.

Do i have to change something in the Repetier Firmware to let it work ?

Thanks in advance.

time to time
UI display
X:.00 Y:0.00 Z:0.000 Speed:100% Flow:100%
instead of
X:0.00 Y:0.00 Z:0.000 Speed:100% Flow:100%

because it is a modification of stored string it means original data is corrupted or replace is buggy in some way

instead of setting 192.168.0.1 as set in configuration, IP is 192.168.4.1 which is the default one

to avoid to be dependent from web connection - a light css with only necessary items would be easy to be embedded in web page to give nice use experience when disconnected from internet - like in AP mode - here the current UI when connected to internet

I connected HX711 to my arduino uno and trying to upload the data from it through the digital pins (7,8) to an website . The code is uploading perfectly but when I open the serial monitor im getting this....

Feature request: Separate SSID and password for AP and station.
I guess if you apply on on the AP Configuration page it`ll take over the SSID and will try to start an own AP with the values of my existing router.

this can be seen when using a long time (memory leak ?) but memory says 24k when going to Home

result is connection is lost need refresh page manually, all history of status/error/info is lost

webinterface.cpp: In function 'void handle_css()':
webinterface.cpp:1738: error: 'class ESP8266WebServer' has no member named 'send_P'

^
'class ESP8266WebServer' has no member named 'send_P'

just tried to compile it on Arduino 1.6.5-r2 win7 using

as baud are big integer is not enough

was working before - but this may due to some change done for port customization

It use 26K eating 50% of available SPIFFS - and no favicon.ico can be added - neither UI for SDCard management and EEPROM management - reducing fancy UI will allow to add the missing space for additional feature on on 64K SPIFFS
Target is less than 10K :
possible ideas :

• remove range controls
• using button instead of picture for up and down and home
• use radio button to set the step 0.1/1/10

I guess my function to send big page in several part is conflicting with new embedded one

Will give a try removing it

randomly this exception apear but I was not able to reproduce it on simple sketch so it is not module issue but code issue.
I do not know where the issue come from - I know urldecode function may bring this issue as it is not secured yet but this happen just on page navigation not on queries so it is not urldecode.

As I will rewrite UI engine with a template engine, I will review all pages and enhance memory checking, I hope this will fix this issue

this is due to string management different than in sandeep's module
if remove all macro F() and all PROGMEM it can compile and ESP is working properly

need to see how to handle this

to save place and have easier management

seems printing progress display in info channel - so no need to display in status

as current one is too heavy and cleaned one in buggy

Hi, id would like to test your ESP8266 firmware, but do the DaVinci really have enough power on the connector ? Or should i connect the esp to the main 5V rail ? Im just asking because i dont know where the 5V line is connected, i dont want to burn the poor SAM....

Sorry for my english.

Thanks in advance.

use default settings without updating EEPROM if Station mode failed to connect

just in case of
