That's probably caused by a bug in the firmware version you are currently running, most likely triggered by an unusual setting in config.g. Which firmware version are you running?

firmware version 2.0 -

Please upgrade to firmware 2.05.1. Read the upgrade notes first.
Here are two ways to get around your current issues to do the firmware upgrade:
-
Move the SD card to a PC and rename your config.g file to something else. Create a new config.g file that enables the network interface and does very little else. That will probably avoid the error.
-
If that fails, see https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_1.

will do, thank you for your swift reply. -
@b45666 Update your Wifi server version, too; you're on 1.21, latest is 1.23. See https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Updating_WiFi_firmware
It looks like you're just setting this up, on USB power. Your temperature sensors are reading 2000ºC, which means they are shorted, rather than disconnected. However, you also get this if you are using a RepRapFirmware v3 config.g with RepRapFirmware v2. So you may need to redo your config, or update to RepRapFirmware v3. Post your config.g if you are unsure.

yes, this is my initial setup,Im getting tips from here and there for each part due to the lack of a step by step guide for my machine (CR10 S5) which I intend to upgrade with a Duet 2 wifi.
here is my config file.

Feel free to write a guide for the CR10 S5 for the wiki!
Your config.g is for RepRapFirmware 2, so for now I'd stick with that. You can load your json file into the RRF config tool, and continually tweak it, getting closer to a setup that works for you out-of-the-box. Follow the general guides for each section on the main documentation pages, particularly:
https://duet3d.dozuki.com/#Section_Hardware_and_Wiring_Gen_2_Duets
https://duet3d.dozuki.com/#Section_Firmware_configurationThere are also a number of other forum users who have CR10 S5, so I'm sure searching the forums and asking them questions would also help. And everyone else on the forum!
