I just tested it with out shutting the heat off and it works just fine, thank all for the help.

I Just added the T0 and the next time I have this issue I will take a screen shot.

Is there a command I can type when the temp isn't changing to see what the duet thinks it is told? That way I can find out if it is the duet or if the web interface is causing me the issue?

Thanks for the suggestions. I figured the problem out I have to set the temp 1c higher than what I want my max to be in my config.g file.

I have this in the config.g but it still will not let me go that hot.

As far as I can tell the temp isnt changing. The next time it happens I will set it to zero and wait a while to see if it is dropping and not showing or the temp is staying.

@phaedrux

Yes it is.

I have had an issue with my hotends some times not changing the temperature when I change it in the web interface. When it does this all I have to do to get it working again is to switch it off and then back on. So far I have only had the issue while I am heating up my hot ends to change filament and then I need to change them temp and it will just stay at the previous temp it doesn't matter what I set it to.

This is the firmware I am using.
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0 (2022-03-15)
Duet WiFi Server Version: 1.25

I read if you do not turn the heaters off they can mess with the Bltouch's reading.

Thank you that did the trick!
