[SOLVED] Multiple problems: Wifi, Extruder and Temp reading

RachDev

I'm on my second Duet board. The enclosed config.g worked on the first board with the exception of an odd problem where E0 wouldn't work but E1 would. I had tried different motor wires and different steppers, but with a known good set only E1 would work.

I have the replacement board wired. At first it was looking good. XYZ motors and stops worked. Then I tried E0, but I had errors in the log. Even though T0 is defined in the config file it seems to ignore the T0 command. It complains of no tool being selected.

The temperature thermistors initially worked but now both report as open. (2000C).

Issue 2 is that the WiFi doesn't connect. I'm definitely using the correct SSID and key. I see one single flash from the WiFi card but the network seems to not connect.

Thermistors reading 2000 normally means either that they are disconnected or shorted, or that you have a short between your thermistor wiring and something else.

To diagnose the WiFi issue, connect to the Duet via USB from a terminal emulator running on a PC, and send the appropriate M587 and M522 commands as described in the Getting Started section of the wiki.

Apparently the temperature problem was a bad server bin file. I updated to the 1.21 file and it magically disappeared.

The extruder problem turned out to be a bad cable - easy enough to fix.

That just leaves the WiFi, which is quite puzzling after playing with it for while. I did reset my wifi box in case there was some glitch.

I worked on the WiFi. I did have the wrong SSID, unfortunate fixing it did not fix the connection problem. I did double check connecting my mobile to the 2.4 to make sure nothing silly was going on like a different password, but it connected fine.

It looks like the WiFi doesn't see the named network:

M552 S1
SENDING:M552 S1
WiFi reported error: no known networks found
WiFi module is idle

to me. I live in a complex, is it possible it just isn't looking through enough SSIDs?

I guess it's possible, but unlikely.

When you send M587 with no parameters, does it list EXACTLY the SSID of your network? SSIDs are case-sensitive.
Is your router definitely transmitting that SSID on 2.4GHz? The WiFi module on the Duet doesn't do 5GHz.
Please confirm that you have not set up your router to hide the SSID.

@dc42 thank you. For all the years I've worked at software and used networking I missed that pronterface was upcasing the line which meant it no longer matched the ssid. I went to repetier and did it there and now the webui is up and running.

Thanks for your help
