[Grbl_Esp32 Issue#693] Uploaded Test Drive, connects to network but I can’t connect to ESP3D WebUI via http://grblesp.local/

Are you connecting to the WiFi access point it creates or using your home router?

192.168.21 is not correct. Is that a typo?

I initially tried to connect in AP mode but couldn’t get it to establish a wifi connection directly to GrblEsp so then I set it in STA mode which connected to my LAN.

192.168.21 is the IP of the ESP32, no typo; message above was copied from Terminal and I verified it with NETGEAR router manager: attached devices.

Wireless Devices (Wireless intruders also show up here)
#IP Address Device Name  MAC Address
1192.168.1.21 — 30:AE:A4:DD:A6:6C

I alternatively tried building/compiling/uploading again with platformio.ini :
[common]
build_flags =
-DMACHINEFILENAME=4axisexternal_driver.h
-DCOREDEBUGLEVEL=0
-Wno-unused-variable
-Wno-unused-function

but got the same results; as soon as I try to connect to hostname:http://grblesp.local/ or directly to 192.168.21 it bricks the ESP32.

“192.168.21 is the IP of the ESP32, no typo;”??

Try 192.168.1.21

Do you mean reboot or brick?

#4 – bdring 于 2020-12-04

Before doing anything with the WIFI try issuing this command..

[ESP710]FORMAT

This will reformat the SPIFFS. This can get corrupted if different types of upload were attempted.

Then power cycle the ESP32.

my bad, they were typos – I have been trying 192.168.1.21

probably not using brick correctly – it goes non-responsive

OR should I say WENT non-responsive… [ESP710]FORMAT -> Power Cycle -> http://grblesp.local/ -> ESP3D -> Load Index.html.gz = SUCCESS!

You’re the man Bart! Thanks a lot buddy!

Now if I wanted to modify my MPCNCV1p3 (I made a copy of your MPCNCV1p2 board but modified it to work with TMC2208’s) to work with a 4th axis; and I cut the trace that connects YDir to Y-B and jumped a wire to Y-BDir from open GPIO(0) to use as ADIR? and then use YSTEPB (GPIO(21) as ASTEP? Would this work or do you see any obvious problems I’m missing?

The issue you had is in the FAQ. It is rare. @luc-github might have a better explanation of the cause.

Your MPCNC mod might work. GPIONUM0 is used to trigger the boot loader. You should see if it affects the ability to upload firmware.

Closing issue.

FS corruption due to partition change is a known issue and description in FAQ is correct – it is ESP32 core / SPIFFS problem not in FW -that said I have some ideas on how to contain/prevent the crash / dead loop and it is my todo list, but because it is an edge case and busy with 3.0 it is not in the top yet
