ESP8266 WIFI Config

[mohamedhamdiahmed]

Hi there.
After enabling wifi on the ESP8266, I can't use any wifi command for editing and controlling wifi. I either get "ok" with some commands like$wifioff or get an exception and a reset when setting ssid for example or $wifion.
Also, I find an open AP named ESP-048817, but after connecting to it, I can't access the web interface (I followed instructions in this decision)
I use uCNC latest version.

Your help is appreciated. Thanks.

Here's the exception:
Exception (0):
epc1=0x40206a58 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

If you are using the web builder please send me your config. This will help me to reproduce the issue.
I'll check this later this night.

Here's the web builder config: ucnc_build.json

Also, another issue came up. I use for limit X, Y, Z and the probe the pins 4, 5, 12 and 16 respectively (to my understanding they are the GPIO4, 5, 12,16). I can't figure a way to wire them in a way that make them work. When measuring the voltage of the pins with a multimeter, I get 3.3v in all mentioned pins except pin 5 (reads 0v). I tried this with the options Enable internal pullup resistor and pullup option in the Board pin mapping enabled and disabled, and still same issue. Can you help me with that too, please?

Also, whenever I use any pin from the left side of the NodeMCU (like GPIO 9, 10, 6) as input, I get the watch dog reset issue in issue #812 even if F_STEP_MAX 20000. Switching to pins on the right side (like GPIO 12, 4, 5) makes everything work fine.

The first tests I performed points this to an issue again with the 74HC595 and the way outputs are implemented on the ESP8266 (#812).
I had to lower F_MAX_STEP to 20000. (this will probably make stepping acceleration seems a bit more choppy)
I also add to add a modification to the EEPROM emulation to prevent crashing that you can get here
This is just temporary fix for this.

I'm working on a refactoring of the ESP8266 code here but I still have a bit of work to do.
